Video from a CCTV camera, saving video to a flash drive, hard drive, to the cloud, to an SD card
Security cameras. these are devices that help in various fields of activity. They allow you to exercise control over production, keep your personal property safe. Modern cameras can not only record images, but also transmit sound, save data to external media. To choose the best way to save data, you should understand the features of each type of media.
CCTV cameras with recording function
Most modern recording devices have a video saving function. But usually such devices are understood as IP cameras. They are computers to which video and sound elements are connected.
Video “How to save video material.” Information storage methods
There are different ways to save information to the cloud. The main types of storage are:
Each of the methods has its own advantages and disadvantages, which you need to understand before buying. In the first two cases, the video cameras work remotely. Recording to a hard disk requires connection to a DVR, and for cloudy saving you need Internet access.
To USB stick
Saving information to a USB flash drive is similar to writing to a memory card. They differ in the installation method and the amount of memory. The card is inserted into the body of the device, and the USB is connected to the corresponding connector.
How to upload video from a CCTV camera to a USB flash drive:
- Remove the drive from the camera.
- Connect USB to Computer.
The saved files need to be transferred to the PC.
To sd memory card
The memory card is most commonly used in IP cameras. It has the following characteristics:
- Memory size.
- Movie speed. It also takes into account the compression method, image quality, the number of frames per unit of time.
The image quality also depends on the volume of the saved recording. The better the image, the more memory is needed to save it.
The memory card needs to be together separately. They are NOT included with the recorder.
- The cost.
- Deployment speed.
- Easy to install.
- A wide range of.
- High risk of lost.
- Small amount of memory.
- Short service life.
Cameras with a memory card are suitable for home video surveillance when the tenants of the apartment DO NOT leave their home for a long time.
To hard drive
An additional device is required to write data to the hard drive. recorder or PC.
Such a medium has more advantages than an SD card or flash drive. These include:
High level of reliability.
Hard drives are commonly used to guard country houses, cottages, military installations, parking lots and other places where constant monitoring is required without replacing equipment. The recording will be performed for a long time, during which it is not necessary to clean the memory and transfer the data to another medium or computer. It is enough to clear the storage once a month or even less often, depending on the remaining memory.
Into the cloud
Cloud storage is one of the most modern and promising ways of recording information. Cameras with recording to a remote server are increasingly used in models of domestic production. The device works using the Internet. The picture from the camera is transmitted to the server with the possibility of broadcasting on the Internet.
Thanks to remote servers, you can hear what is happening at the guarded facility, as well as talk with people on the other side of the camera.
It is possible to simultaneously connect to all servers from one device. Then on the screen you can watch online what is happening in several places. View can be accessed by both one person and a group of company employees or all its visitors.
The advantages include high data security, a wide range, the ability to view records from anywhere and a large amount of memory. Disadvantages. Internet access costs and low bandwidth.
How to make the best choice
The range of CCTV cameras is very wide, and it is usually difficult for the user to immediately choose the optimal device. But not all camcorders can be used on the streets or in houses, the amount of memory also needs its own for each place. Therefore, it is recommended to select a camera based on the following criteria:
- Choice of installation site Household products are small in size, they are unstable to moisture and other aggressive factors. Outdoor models Must be made in a solid case, have protection from water, ultraviolet radiation, vibration and other negative environmental factors. Recommended Look for vandal-proof devices. Outdoor appliances usually cost more.
- Availability of additional functions. The camera can have a microphone, various sensors, a fixed lens, a Wi-Fi transmitter, and IR illumination for working at night. Depending on the volume of additional options, the price will increase.
- Recording time. To record what is happening around the clock will require a model with a large memory capacity. The optimal choice. camera with cloud or hard drive. For home use, a device with a memory card and a USB flash drive is suitable. On such cameras, you need to periodically clean the place.
- Remoteness of the camera from the monitor. It is better to take a product from which the signal will be transmitted over a distance without loss of quality.
- Viewing angle. Depends on the individual characteristics of the protected area and equipment requirements. For example, if the camera has a small field of view, suitable for indoor work, then it will be possible to see in detail all the people caught in the lens.
You should make a list of the requirements for the camera in advance, and then choose a device. For home, budget gadgets with medium resolution are suitable; for the protection of large enterprises, video cameras with high definition and the best color reproduction are needed. The complexity of working with the equipment is also taken into account. Even an inexperienced user can figure out how a video is overthrown from a security camera onto a USB flash drive or memory card.
CCTV cameras are an essential part of a security system. Information from them can be saved to various digital media. memory card, USB drive, hard drive and the cloud. Choosing the best device depends on your camcorder requirements, budget, installation location, and the need for additional features.
Video surveillance with recording
Security cameras. irreplaceable human assistants in many areas of activity, from the protection of personal property to control over production. The more functions such equipment has, the more useful it is, although for most users it is quite enough to simply record a picture with sound. In this article, we will look at different types of cameras that save a record on any media, and also learn how to navigate among the offers of the modern market and make the right choice.
Which cameras allow you to save a recording
Almost all modern CCTV cameras predict the possibility of saving a recording, noting everything that happens on a particular device (for example, on an SD card or USB drive).
However, such devices are often understood as IP-surveillance cameras, which, in fact, are not just a video camera, but real stand-alone computers, with video and sound receiving elements connected to them.
The video signal received from the sensor is compressed using special codecs and can be transmitted to a local or worldwide network for further processing.
A standard stand-alone video camera with the ability to record on a USB flash drive will be quite enough for arranging video surveillance in one room or on the street, because such devices are capable of capturing a fairly large space.
Did you know? In 1964, the Japanese company Sony created the first portable video recorder. This model, CV-2000, weighed 15 kg. comparatively few, since competing devices were at least 6-7 times heavier. Again, it was Sony who was the first to combine a video camera and a VCR in one case, but this happened 20 years later.
Depending on the specific method of storing the information received, all modern video cameras are divided into several types.
They can use:
- SD memory card,
- USB drive (flash drive),
- Remote server (so called “cloud”).
In the first two cases, the camera will work autonomously, the third option requires connection to a DVR or computer, and the last. organization of Internet access. Let’s consider each of them in more detail.
To SD memory card
Recording to a memory card is more typical for IP cameras. The quantity and quality of recorded video archive data is determined based on the following indicators:
- The volume of the card. should not exceed the values supported by the device;
- Movie speed. Consider resolution, video compression method, number of frames transmitted at a specific time, etc.
For example, to record an hourly image with a resolution of 1.2 megapixels and a frequency of 12 frames per second, with H.264 compression, you need to purchase a card with approximately 990 MB. Recording from the Video Archive can be viewed on a computer or TV by using a special adapter.
Important! Keep in mind that memory cards need to be purchased separately, as they are almost never included with the device itself.
The advantages of using camcorders with memory cards include:
- Affordable cost of devices,
- High speed deployment,
- Easy installation,
- Big choice.
Among the negative aspects of the application, it is impossible not to single out a sufficiently high probability of loss (it will NOT be difficult to remove such an information storage device from the equipment), small volumes (inconvenient if you need constant round-the-clock video recording), a relatively low service life.
To USB stick
USB stick. or, as it is also called, “flash drive”. is in many ways similar to the described memory card, and the most characteristic differences between these media are:
- Type of connector for connecting to a video camera;
- Maximum allowable information capacity.
An SD card is usually inserted directly into the body of a video surveillance device, and a USB flash drive acts as a connector and is connected via a special connector for USB.
Considering that cameras (including models with a USB drive) have to work around the clock, they are supplemented with a special option: infrared illumination, which provides a sufficient level of visibility even at night. This mode is activated automatically as soon as the light level starts to decrease.
An additional advantage of almost all such devices will be the binding of a recording or photograph to the exact date and time, which will help in the future to find the necessary material.
To hard disk
Unlike the previous two options, in this case, in addition to the video camera itself, one more device is needed. a digital video recorder or computer as it is NOT a recorder itself.
It may seem to some that such a solution is very inconvenient to use, but in fact, a separate hard drive has quite a few advantages in comparison with an SD card or USB drive:
- Excellent ratio of basic characteristics and pricing policy,
- Almost 100% reliable.
A video surveillance system with recording on a hard disk will be appropriate for the protection of country houses, industrial facilities, banks, military facilities, cars and in other places where long-term monitoring is required without replacing equipment and it is possible to install a computer or video recorder.
Did you know? The hard disk of the first serial computer IBM 305 RAMAC, which began to be produced in 1956, weighed 971 kg and fit in a drawer from a large refrigerator, and its memory volume was only 3.5 MB.
Whichever method of recording the creators of the video camera choose, any of them will store information for exactly as long as the capacity of its built-in or connected media is enough: in some cases, you will have to regularly remove and clean the USB flash drive, while in others it is enough to clear the “storage” once a month, or even less often.
The operating time of the device is also taken into account: around the clock or only a certain time.
Into the cloud
Video cameras with the ability to “cloud” recording are gaining more and more popularity among domestic users. The essence of the process of saving a picture is to transfer it through a remote server, with the possibility of broadcasting on the Internet.
Cloud video surveillance allows not only to view everything that happens from the archive or online, but also to hear and sometimes even communicate with people “on the other side”.
If you simultaneously connect to all servers from video recording, you will be able to view images online from one client location.
Also, all employees of a particular enterprise or all visitors to a site can have access to an installed group of cameras, or only a few people, and while some clients will be able to view the archive, others will only see what is happening in real time (differentiation of access rights).
As for the advantages of installing cameras with recording in the cloud, among the main ones are the security of storing footage (the processing center has the highest data protection rates) and a large selection of IP video camera models (medium).
The disadvantages of using such equipment include low bandwidth and the need for a subscription fee for Internet access.
How to make the best choice
The modern market offers its consumers a truly huge selection of a wide variety of models of video recording cameras, but in order to pick up really worthwhile equipment, you need to proceed from the requirements for a video surveillance system.
Simply put. then devices that are great for the street are unlikely to be useful in small rooms, since in addition to their overall dimensions, they also do not always have the proper level of expansion, we “lubricate” small parts. Let’s consider several requirements for “home” and outdoor cameras.
If you need to record everything that happens around the clock, you should also take care of the presence of IR illumination in the night recording mode. You can view the footage on a tablet or smartphone.
Important! In rooms with high humidity levels, it is necessary to install cameras in a waterproof housing.
Street. For outdoor devices, one of the main requirements will be good protection from external weather influences: rain, wind, frost and direct sunlight. It can be provided by special casings or housings that maintain optimal temperature indicators and acceptable humidity inside.
Also pay attention to the remoteness of the camera from the monitor on which the picture is displayed: it is better to give preference to models in which the signal transmission will be performed without loss of quality.
A good advantage for any outdoor video cameras (dome, box or pivot) will be the presence of a robust anti-vandal case.
If you need to observe objects located at a distance of 30-40 m from the device, a viewing angle of NOT more than 45 ° will be sufficient. If you need to cover the whole room, it is advisable to give preference to models with a visibility of 90 °, but when viewing it will be very difficult to see small details.
In a word, there are a lot of cameras with the ability to record video, and the best of them will be the ones that can fully satisfy all the buyer’s needs and are suitable for specific operating conditions. For home video filming in a residential area, a budget device with a mediocre resolution will suffice, while for monitoring large industrial facilities you will need a camera with higher performance and the most clear color reproduction.
CCTV camera with recording on a flash card: the main points of choice
Cameras with the ability to record video information on a memory card are becoming more and more popular. The use of such devices in video surveillance systems allows you to save serious money, since you do not need to spend on installation work, purchasing a recorder with a hard disk, a power supply and a separate monitor. A video surveillance camera with recording on a flash drive receives power from an autonomous source, which is used as a battery or a battery, therefore an autonomous video camera can be installed absolutely secretly and it is NOT unmasked by wires and cables.
The function of recording video information on a USB flash drive is usually equipped with IP cameras, while the device can only be stand-alone or is designed to transmit a signal over a GSM or Wi-Fi channel. An autonomous device works “for itself” and to view the Video Archive, you need to remove the flash card and insert it into a computer or laptop equipped with a USB port.
Like conventional CCTV cameras, the signal from which is transmitted through a cable, stand-alone cameras with a built-in recorder have certain technical characteristics. These are the standard parameters of any camcorder:
- Video stream transmission rate;
- Signal to noise ratio.
In addition, CCTV cameras with recording on a USB flash drive are characterized by some Special characteristics:
- Depth Video Archive;
- Record type;
- Video compression method;
- Availability of additional options.
Usually video cameras of this type are designed to work with a flash card of a certain size. It can be a 16 or 32 GB flash drive. Video Processors Some cameras accept 64GB and 128GB memory cards. Cards with a capacity of less than 16 GB are generally not used. Here is the capacity of the solid-state drive and the number of frames recorded per second, the depth of the Video Archive depends. In modern models of video cameras, the principle of cyclic recording is used. This means that when the flash drive overflows, the recording does not stop, but to free up space, the previously recorded files are erased. In order to save space, the video signal is compressed and recorded on the memory card in a compressed form. The most commonly used compression algorithms are MPEG-4 and H.264.
Since any video recording is relevant only in case of an event, it makes no sense to record if nothing happens in the area where the camera is installed. Therefore, the most popular model is a video surveillance camera with a motion sensor and recording. A camera of this type is equipped with an infrared sensor, which reacts to the movement of a material object that has fallen into the range of the sensor. Triggering the sensor activates the recording mode, which automatically turns off after a certain time. Video recording can be carried out in several modes:
- Permanent recording;
- Frame-by-frame recording;
- When a motion detector is triggered;
Constant video recording is used quite rarely, since in this mode the resource of the flash card will be quickly used. The camcorder can be configured to record frame by frame, for example, 1 frame per second, which will save space on the memory card. With the built-in timer, you can schedule the recording mode on and off at a specific time.
The functionality of some models of camcorders allows, instead of recording a video, to carry out a series of sequential photographs, which allows, with a small capacity of a flash card, Get a very decent photo archive.
Since CCTV cameras recording to a USB flash drive must work around the clock, they are equipped with a special option. This is an infrared illumination that allows you to record an image in the dark. This mode turns on automatically when the illumination level drops below a certain limit. The CCTV camera is also equipped with a calendar and clock, so every video or photo is precisely linked to the date and time of recording. The microphone, available in almost all camcorder models, allows you to record a video file along with sound.
Recently, cloud camcorders are becoming more and more popular with the transmission of images to the Internet through a remote server. Setting up video surveillance with such cameras Takes a matter of minutes. you just need to install a simple application for Android or iOS and use it to make the necessary camera settings. After that, you will be able to observe what is happening in your home or apartment at any time from anywhere by simply connecting through your smartphone to a video surveillance camera. Read more about cloud cameras in the article: http://nabludaykin.ru/obzor-ip-kamer-dlya-videonablyudeniya-cherez-internet.
For remote autonomous video surveillance, you can use small mini cameras, with which you can even organize covert video surveillance. Their miniature size allows them to be installed invisibly to prying eyes, and the presence of a built-in power supply and a micro SD card makes it possible to record from almost anywhere. You can read about wireless mini cameras here.
Advantages and disadvantages
CCTV cameras with memory card recording have a number of fundamental advantages:
- The ability to implement video monitoring in places where there is no GSM and Wi-Fi;
- Viewing information at any convenient time;
- Operation of the system is possible in the absence of power supply;
- Low cost of a standalone video camera;
- The possibility of hidden installation;
- No installation and equipment costs.
Quite often, you can face the need to implement video monitoring in places where the signal is difficult to pass, and it makes no sense to mount a stationary video surveillance system for some reason. Installing a compact video camera with recording, which is triggered by a motion sensor or on a schedule, can easily solve this problem. The information recorded on the solid-state drive can be viewed on the computer at any time, as well as dumped to the hard drive for storage, and the USB flash drive can be used for further use.
A stand-alone video camera with a recording can be positioned so that it is not visible. This can be done at home or in the office, but in order not to break the law, you must warn everyone that video surveillance is being conducted in the room. But it is absolutely not necessary to reveal the point where the video camera is installed. A standalone video camera with recording is inexpensive and allows you to do without installation work and the purchase of expensive equipment that is required for the normal operation of a video surveillance system.
The disadvantages of autonomous video surveillance include the need to control and timely replace the camera’s power supply and a small amount of video archive.
Small-sized video surveillance cameras with recording on a flash card can be used both in residential and industrial premises. Often such cameras are used on very important objects, such as duplicating the main surveillance system. With the help of modern technical means, cable video surveillance can be disabled, but all information about the attacker will be recorded on secretly installed autonomous cameras. CCTV camera for home with recording has found wide application in Video Peephole, when every visitor who gets into the detection zone of the motion sensor will be recorded on a video or photographed.
Video cameras with recording are used in domestic conditions, to monitor the service personnel, and especially to monitor the babysitter who is invited to small children. The head of the company can assess the performance of employees, their professional duties, installed compact cameras with recording in the office premises. Video cameras in ATMs also record video information in clients on a flash card. The recording starts as soon as the client comes close to the ATM.

Standalone CCTV camera with memory card recording Occupies a special niche among CCTV cameras. This is due to the possibility of its use in any room, be it an office or a residential building. One of its subspecies is a surveillance camera with recording on a memory card.
Its installation will be the ideal solution that will eliminate the need to purchase expensive equipment, such as a video recorder, a hard disk where the captured data is stored, as well as the need to lay cables and purchase other peripherals.
Scope of cameras with a memory card
A video surveillance camera with a memory card is perfect for recording events that take place at home during the absence of its owners, for example, to observe the actions of a nanny or governess. All the need to somehow customize this camera. To ensure the operability of the device, it is enough to install it in the selected place, adjust the required viewing area, then insert the card and supply power to the device. camera is ready to use.
To view the footage, you need to remove the USB flash drive and insert it into a computer or laptop, if necessary, save the captured data on them. A surveillance camera with a memory card records in cycles, i.e. When the space on the map runs out, the camera begins to write the “floor” of the old data, Erasing the previous recorded data and so on, cycle by cycle.
A surveillance camera with recording on a memory card will be a good solution for a small office located in one. In two rooms, the director will be able to observe the work of the staff during his absence and view the recorded video from the flash drive.
Also, these cameras can be used:
- At various enterprises, as well as service enterprises;
- Small offices;
- Various living areas;
- Construction sites, etc.
Camera with SD card recording
The main advantage of self-contained cameras. Save the captured image to portable media and quickly access it. If you save data to a computer, you can make a data archive.
Among the advantages are the following characteristics:
- Possibility of installation in any required place. The main condition for choosing a place. Availability of power supply. The ability to quickly reinstall the camera and easy installation.
- There is a need for a DVR.
- “Motion recording”, which allows you to save space on a flash drive.
- Some cameras can send footage to the Cloud Service.
- High quality of the image taken by the device.
- CCTV camera with recording on a USB flash drive can be installed wired and wirelessly, depending on the device model.
- Infrared illumination for 24/7 surveillance.
A surveillance camera with recording on a USB flash drive has the following disadvantages:
- The need to constantly monitor the operability of the device (if the model has an indication).
- Availability of power supply at the installation site, with the exception of battery-operated photo-traps that shoot onto a memory card.
CCTV camera with recording on a memory card. is a device that allows you to organize an effective monitoring system with minimal installation and maintenance costs.
CCTV CAMERAS with recording
Almost all systems existing today predict the possibility of recording images from CCTV cameras to one or another device. Let’s take a look at the main ways to create video archives.
There are several ways to record video information. It can be carried out:
- To a memory card;
- On a USB flash drive;
In the first two cases, the camera can work autonomously. The third option involves connecting it to a DVR or computer.
Analog video cameras can only be used in conjunction with a DVR or PC. Thus, to organize the recording in this case, it is required to build a “full-fledged” video surveillance system.
IP technologies make it possible to implement the recording option in any form, including on the side of the TV camera. Let’s look at each of THESE methods in more detail.
CCTV CAMERAS WITH RECORDING ON THE MEMORY CARD
This method is used, as a rule, by IP cameras. The depth of the Video archive obtained in this way is determined by:
- The memory capacity of the card (of course, it should not exceed the values supported by the device),
- Video stream speed (depends on the resolution, video compression method, the number of frames transmitted per unit of time, the presence of the motion detection function).
For example, to record a 1.2MP image at 12 frames / second in H.264 compression for 1 hour, you need a card with a memory capacity
= 2.2 Mbit / s 3600 s / 8 = 990MB where:
- 2.2. Corresponding bit rate (Mbps);
- 3600. Recording time (seconds)
- 8. Conversion Ratio Bits to Bytes.
VIDEO SURVEILLANCE CAMERAS with recording on a USB flash drive
At its core, a flash drive is not much different from a CD card. The most significant differences are:
- The maximum possible amount of memory;
- Connector type for connection.
If the memory card can be inserted directly into the camcorder body, then the flash drive uses the USB connector as a connector. It is usually placed on a flexible conduit outside the cctv camera body.
Recording from camera to hard drive.
For analog video cameras, it can be carried out using a video capture (video capture) card installed in a computer or on a digital video recorder, that is, a separate additional device is required. The IP camera can be connected directly to the PC, but, in any case, the camera here is NOT a recorder.
CCTV recording time.
Regardless of the recording method, its storage time is determined by the parameters of the video stream and the capacity of the storage medium: HDD, memory card or flash drive. Considering at the beginning of the article the method of recording to a memory card, I gave an example of calculating the archive depth (recording time).
Video recording software.
When using the DVR, a separate program is NOT required. It is contained in the device itself. For video capture cards Corresponding programs are supplied with the product.
IP video cameras can also work with the software supplied with them. In addition, many of them have their own web client installed directly from the video camera when it is first connected to a computer.
Wireless CAMERA to hide CCTV with recording
The temptation to use a recording camera for wireless covert video surveillance is understandable. Let’s look at the advantages and disadvantages of such technical solutions.
The undoubted advantage, of course, is the lack of wires. This greatly simplifies the hidden installation process. I draw your attention, there are two possible options:
- Use of hidden cameras with the ability to wirelessly transmit data;
- The use of a stand-alone camera that works exclusively for itself.
The first option can cause inconvenience to camouflaged antennas and power wires. The use of an autonomous voltage source requires its periodic replacement, which is quite inconvenient. A rather reasonable question arises. why, in this case, write to a memory card or flash drive. There are several arguments in favor of such a decision.
First, you can opt out of recording on the side of checkpoints. You can simply periodically remotely view the information on the carrier. If necessary, noteworthy files can be selected manually and downloaded.
Secondly, the wireless transmission rate may NOT be stable and may vary depending on the time of day, the electromagnetic environment, and the load on the WI-FI network. True, in addition to digital technologies, there are also types of wireless video surveillance cameras, but IP systems are best suited for THESE purposes. But we are somewhat distracted.
The second method is applicable if a hidden camera is installed temporarily. Otherwise, the need to read information from the recorder will cause a lot of trouble.
HOME VIDEO CAMERA with recording
The first thing to do before choosing a home camera capable of recording. it is determined with the goals and objectives that you are Pursuing. I constantly mention this, since this moment is decisive when choosing the technical characteristics and options of the device.
Several of the most common options:
- Installation of outdoor video surveillance to control the surrounding area;
- Installation of video surveillance for monitoring children, elderly relatives;
- Controlling incoming workers (I don’t like the word “servant”)
- Purchase of cameras for the organization of video surveillance.
In the first case, special “frills” are not needed. Therefore, you can install a DVR and connect cameras of any type to it. It should be noted that in this case, you can get practically unlimited depth of the video archive and DO NOT worry that the recording will be interrupted at the most inopportune moment.
For remote monitoring, a video camera with support for recording to a card or flash drive will be useful as a way to level the variable speed of the Internet connection. If, for some reason, the Internet channel temporarily “falls off”, the information will be saved on the side of the TV camera and, when the connection is restored, sent to the “cloud”.
For some reason, it is believed that the surveillance of incoming workers should be hidden. In this case, I don’t see any particular benefit in using a camera with recording on the built-in media at home. Installing a hidden camera is often more difficult than hiding a recorder. An exception. again, remote access via the Internet.
If we talk about security, then in this case, video surveillance is best used in integration with a burglar alarm. There are enough technical solutions to implement such tasks.
Thus, the use of CCTV cameras with recording for a private house in most cases may be inappropriate.
VIDEO FEATURES AND FUNCTIONS
When using any method of creating a Video Archive in order to save media memory, the following recording modes can be used:
- By motion.
For this, the recording device has a day of the week and time settings, during which video recording of events will be carried out.
A very popular and effective mode, the essence of which is to configure the field of view, when motion is detected in it, the required video fragment will be saved on the appropriate media. The motion detector can be implemented on the side of an external recorder, DVR or PC, or directly by means of a video surveillance camera. IP video cameras have such capabilities.
Also, pay attention to the overwrite function. When activated after filling the video storage media, the oldest recordings will be automatically deleted, providing space for new files.
Concluding the topic, it is worth saying a few words about the organization of recording for covert video surveillance systems. The temptation to use a camera with a memory card for this is quite large, however, the peculiarities of its installation can make reading (viewing) the necessary information rather difficult due to the limited access to the device in question, which was already mentioned above.

Today there are many video cameras for surveillance systems that do NOT anticipate the connection of DVRs. Video recording from cameras is carried out inconsistently on the SD card, which is inserted into a special slot of the video camera.
Such video surveillance systems are usually used where there is no need to constantly monitor the situation at the protected facility. Due to the absence of a video recorder in such a system, connected via a cable or wireless line from a video camera, you can seriously save on a video surveillance system.
However, many people have a question, how, in fact, to set up recording from a camera to an SD card, since simply putting it in the camera is not enough.
Let’s start with the first steps. To start:
1.Power off the camera. 2. Unscrew the back part 3. Here you will see a slot for installing a micro SD card 4. Install it and screw the back of the camera tightly.
After that, you need to go to the WEB interface in the Settings / Storage settings / SD / USB drives section. Be sure to make sure the camera sees the memory card. It is better to do this before mounting the camera in its place where it will work. Then click the Initialize button when it is finished. reboot the camera to see the new format.
The camera formats the memory card for its file system, which means that when you insert the card into the PC, you will NOT be able to read it, and accordingly you can see the records too. To view the recordings, use the camera’s WEB interface.
For example, in OMNY cameras this is done like this:
After that, go to the “Quick Setup” tab to set the date and time. In this case, the camera will record video in accordance with the set time.
Now let’s move on to setting up recording to an SD card. Select the tab “Storage settings” Quota and overwrite. Here you can choose what to do when the memory card is full. It is best to choose a loop recording.
Next, go to the “Alarms and reactions” tab to configure pre-recording and post-recording. This means how many seconds to record in the occurrence of motion and at the end of it when the motion sensor is triggered. Usually 10 seconds are enough for this.
To record by a motion detector, go to the “motion detector” Specify the sensitivity, detection area, schedule of the detector
For permanent recording at the specified time, go to “storage settings / Schedule ANR
Recording is set up, leave the camera for 5-10 minutes to record the first files then go to the Archive tab to check if there are any recordings
The files can be downloaded to your computer. The file download path can be viewed in System Preferences / Local Directories. The download path can be changed only in the IE browser.
We enter the web interface of the ip-camera, indicated its IP addresses in the address bar of the browser (for example, we used Internet explorer, and how there are more settings in it.
Let’s go to the management tab. memory setting where you need to format the SD card
Next, go to the Monitoring tab where you need to enable recording (here you need to select the recording mode, continuous, schedule or by motion detection), clicked the START button
The result should look like this:
To set up web browsing. go to the tab “events and alert”. viewlog. put a tick on “Activate”. then click apply (for remote viewing of the archive, forward port 5552 by default on the router).
To view the archive, you need to run the “video log” utility which you can download on the file server.
Go to the “Service” tab. “Remote viewlog service”
Enter the IP addresses of cameras, ID and password, host type. “GV IP Device”
The archive view is now available.
Below we provide a video where you will find several more examples of setting up recording to a card from CCTV cameras of second manufacturers.
We reviewed the setup of video recording from CCTV cameras from various manufacturers. As you can see, the principle is the same: formatting the card for the camera, installing it, setting the date and time, setting the recording to be triggered when motion is detected in the camera’s view area and, in fact, recording video.
In CCTV cameras of second manufacturers, the settings for recording video to the sd drive are similar. The only difference is the interfaces in which you need to make these settings.
