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 GoPro 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.

Information storage methods

There are many 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 cameras work remotely. Recording to the hard disk requires connection to the recorder, and for cloudy saving you need Internet access.

On this topic. To usb drive

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 transfer from a surveillance 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.

How to make the best choice

The range of surveillance cameras is very wide, and it is usually difficult for the user to immediately select the optimal device. But not all cameras can be used on the streets or in homes, the amount of memory also needs its own for each location. Therefore, it is recommended to select a camera based on the following criteria:

• Choice of installation site. Home 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 best choice is a camera with a cloud or a 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, 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 to reset from a surveillance camera to a USB flash drive or memory card.

Surveillance cameras with recording function

Most modern recording devices have a save function. But usually, such devices are understood as IP cameras. They are computers to which the recording and sound elements are connected.

To hard drive

To write data to the hard disk, you will need one more device. a 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.

From a surveillance camera, saving material to a flash drive, hard drive, to the cloud, to an SD card

Surveillance cameras 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 on an external medium. To choose the best way to save data, you should understand the features of each type of media.

“How to save material

How to choose a camera for surveillance?

Today there are so many different types of surveillance cameras that it is very easy to get confused in this variety of choices. In order to choose the right camera, you first need to understand what needs you plan to use it for, as well as determine the number of cameras, their technical characteristics, etc.

To facilitate your choice, we wrote this article, in which we gave 7 main criteria for choosing a good surveillance camera Based on the specific tasks.

Analog or digital surveillance cameras?

The difference between analog and digital cameras is that the former work with NTSC and PAL signals and have the ability to directly connect to a monitor, and if you want to record what is happening, you will additionally need to connect to a recorder or computer. Digital IP cameras transcode the data received from the matrix into a digital signal, and using Wi-Fi, 3G or 4G wireless networks transmit the image to a cloud server, computer, or recorder. thanks to this, you can follow what is happening even from your mobile phone, where whatever you are.

Similarly, analog cameras have a resolution limit of 720×576 pixels, and modern digital surveillance cameras can display a picture with a Full HD resolution. 1920×1080, which is several times higher than the possible resolution of analog cameras. Thanks to the high resolution, on recordings from digital IP cameras, it will be possible to discern not only the general features of a person, his figure, clothes, etc., but also his face in good quality, and various small details that would be almost impossible to identify from analog cameras. It is up to you which camera to choose for surveillance. analog or digital, but if you put image quality at the forefront, then digital IP cameras will be the best choice for you. And if you are planning to install surveillance with your own hands, you may need this information.

We install it outdoors or indoors?

An example of an outdoor surveillance camera Falcon eye FE IS720. Price

If you are planning to install surveillance cameras outside, then you need to know how to choose a surveillance camera for the street. As a rule, outdoor models are equIPped with a special protective case, which protects the camera from low temperatures and other adverse environmental influences: rain, sun, etc. The camera body must be sealed, and, if possible, equIPped with a heating system for trouble-free use of the camera in conditions low temperatures. If in your area the thermometer does not fall below zero, then take a look at the simpler models.

In order to exclude damage to the equIPment, the Intruder, try to install cameras as high as possible, so that it would be impossible to reach them without additional equIPment. this way you will keep your outdoor surveillance cameras intact and safe in case of encroachments on your territory.

To implement indoor surveillance in the absence of any additional environmental influences, as a rule, ordinary dome cameras without protective housings are used.

Day / night mode and a few words about IR illumination

Thus, if you plan to conduct surveillance both day and night, and want to receive information about all the details of what is happening, including color, choose camera models with “day / night” modes, which automatically switch to monochrome mode at nightfall. A necessary point when choosing cameras for night surveillance is the presence of infrared illumination, which is absolutely invisible to the human eye, but allows the device to monitor even in complete darkness.

The distance of the IR illumination varies within 5-50 meters, but with the use of powerful IR illuminators it can reach long distances. Illumination quality may vary from camera to camera. There are times when the illumination angle does NOT coincide with the viewing angle of the camera lens, while a bright overexposed spot is formed in the center of the frame. In some cameras, the power of the infrared illumination can be adjusted depending on what is happening in the frame, thereby excluding excessive illumination of the subject and the appearance of flares in the frame. Therefore, when choosing a camera for 24/7 surveillance, you must take these features into account.

Viewing angle and focal length

Thus, the smaller the angle of view of the lens, the more detail you can identify when tracking a certain small area, and therefore the wider the angle of view (from 90 °), the more space you can cover. So it all depends on the specific tasks.

Line-Pro 560AHD, 2.8-12 mm. Price

It is also possible to purchase a camera, the lens of which has a certain range of focal lengths. such lenses are collectively called “varifocal”, their approximate range of focal lengths is 2.8-12 mm. When choosing a camera for this type of surveillance, you can later manually change the angle of view depending on your needs. But it is worth noting that this parameter accordingly affects the price. often such devices are much more expensive than cameras, the lens of which has a constant focal length, but for them, as well as for all surveillance systems, tend to decrease. The picture shows an example of a camera equIPped with a varifocal lens. Line-Pro 560AHD with a 2.8-12 mm lens focal length. Its price is 4300 rubles, which, you see, is not so expensive.

Camera sensitivity and lighting conditions

The sensitivity of the camera plays an important role in 24/7 surveillance. The higher its sensitivity, the better the image quality and more shooting opportunities in twilight and dark times of day.

A camera’s light sensitivity refers to the minimum amount of light (light level) at which the camera can “see” what is happening. It is customary to measure the sensitivity of a camera for observation in units of illumination. lux. For example, let’s give a small table with approximate values ​​of lighting units typical for certain places and conditions.

When choosing a camera, be sure to look in the characteristics for what lighting conditions it is suitable for, and select it to suit your needs, after measuring the level of illumination in the place of the proposed installation using a light meter. For 24/7 operation, you will need a camera with a sensitivity of at least 0.01 lux.

In most cases, when installing cameras outdoors, the lighting will constantly change throughout the day. In order to get the same picture under such changeable conditions (without glare in bright sun or dark images in unexpectedly deteriorated weather), it is necessary to clarify that the camera has an automatic adjustment of the lens opening. aperture. By closing or opening the aperture hole in automatic mode, such cameras maintain the amount of light falling on the matrix within constant limits, which excludes the appearance of overexposed or dark images under constantly changing weather conditions and time of day. Therefore, before choosing an outdoor surveillance camera, be sure to check this fact of the presence of automatic aperture adjustment.

Color or black and white camera?

Updating information! For the most part, today all surveillance cameras are produced in color, with the ability to switch to black and white mode at night, so the narrative in choosing between b / w and color in this part of the article has lost its relevance.

When choosing a camera for surveillance, you need to decide whether a monochrome camera is enough for your particular case, or if you still need a color image?

The advantages of black-and-white cameras, first of all, can be attributed to their low price compared to color models. Also, monochrome cameras under poor lighting conditions are able to produce a picture of higher quality without noise, when the image from a color camera under the same conditions will noticeably “make noise”. However, the manufacturers took this fact into account, and began to produce cameras that shoot in color during the day, and automatically switch to monochrome mode after dark.

The disadvantage of color cameras is their higher price in comparison with monochrome ones.

Criteria affecting image quality

Contrary to popular belief, a large number of megapixels is NOT a determining factor in good image quality, but is only one of the elements providing it. Of course, there is definitely a difference in picture quality between standard analog and IP, and it is quite significant, but speaking of the modern market and the race of manufacturers for megapixels, before choosing between 2 and 8 megapixels, it is worth thinking carefully, because K. is often good. IP camera with a resolution of 2MP for 10 thousand rubles. Gives about the same quality as more expensive with higher values ​​of this parameter.

Also, there is almost no difference between 720p and 1080p, despite the double the number of pixels. In addition, when the resolution is increased, parameters such as the sensitivity of the camera sensor and the ability to work in a wide dynamic range (WDR) may suffer, which also affect the quality of the resulting image.

Wide dynamic range. WDR

Example of WDR action

Recently, WDR technology has become much more common. Previously, wide dynamic range was used only in premium devices, but now, thanks to the advent of inexpensive sensors with support for this function, it has begun to be implemented in inexpensive cameras. But do not delude yourself with the presence of support for this parameter in the descrIPtion of the camera. true WDR is still used only in expensive cameras, in most budget cameras. only its similarity, Described by the manufacturer in confusing terms, and “wrapped in an attractive package”.

2 main ways to delete recording files from cameras

One should always pass from theory, in fact, to practice. Now we will tell you how to delete recordings of surveillance cameras.

First, you need to clarify where exactly the footage is stored. They can be both external and internal. Find out what storage was used to automatically save files. It can be local or cloud archive. This characteristic will depend on the way in which it will be easier for you to delete existing records in the future.

Before that, I would like to warn that completely unprepared people are unlikely to be able to cope with such a task, even according to the most precise instructions. Try to find a person who is neither more nor less, but understands this. So with joint efforts you will be able to do what you are here for.

When recording to a memory card

The archive can be stored on a memory card connected to a digital surveillance camera, on a card reader with a memory card, on an external hard drive or on a regular flash drive. Most often, the USB connector is used for connection.

How to delete a recording from a security camera

This question is often of interest to those whose cameras have begun to work pretty well, and the material no longer wants to be written due to lack of space. Be that as it may, sooner or later, you would still have to clean up all the previously made records, because, by and large, you just don’t need them.

Attention! Before you think about deleting files, review them again. If what you saw did not shock you in any way, you can safely proceed with the cleaning. But keep in mind that cameras can not only record the events taking place around the object, but also what happens to people passing by. There are often cases when evidence is needed for the material of a criminal case, so maybe you have it on your records?

In the second cases, the deletion of archived records can be done immediately, but in the verification of materials, in any case, one must not forget.

How to forcefully delete a recording from a security camera?

To delete information from the media, you need to figure out on which device it is still stored, since they can be completely different.

How long are recordings from surveillance cameras kept?

The maximum recording time depends on several factors and is determined solely on an individual basis. The record retention period is influenced by:

• Industry interests.
• Legal requirements.
• Internal control regulations.
• Time of obtaining permission to view.
• The presence of recurring events.

For example, in some organizations there are special services that estimate employees’ work by UAH. Since suchs are carefully and regularly viewed, there is a need for their long-term storage.

The situation becomes more complicated if the recording affects the personal rights of citizens. In this case, you will need to obtain permission for access, which takes a lot of time and this factor must be taken into account when calculating the storage period. Typically, in commercial systems, CCTV footage is stored for no more than two to three weeks.

In most cases, the archived data is stored on the memory card of the recorder or hard disk. The hard disk is reliable and has a large enough memory. For professional systems, this method of storing information is considered the only possible storage device, because we are talking about storing a very large amount of information.

Also, memory cards are not suitable for storing such a volume of data, which are equIPped with car recorders and some models of IP cameras. Models for 32 GB or 64 GB are enough only for maintaining an archive for 1-3 days and even if the recording is carried out using a motion sensor. This period is quite enough for amateur needs.

What if you need to keep recordings from surveillance cameras for a long time? The only way out is to copy all the archived files to a flash drive. It must be stored away from places with high humidity and sources of electromagnetic radiation.

What equIPment does ivideon work with?

The additional support service is quite unique, as it works with almost all cameras on the modern market. However, we will only recommend the types of cameras that are actually tested by many people.

So for example DVR, NVR, IP cameras with built-in iv /

When buying a new surveillance system, we advise you to consult a specialist which camera is best for you. Do not forget to clarify that you would like to work with the ivideon server.

Break the camera

The most primitive way to get rid of the gaze of pesky cameras is to destroy them. For this, the attacker usually chooses a heavy object such as a stone, brick, or metal stick. After that, you need to reach the camera, which is usually located high. At this stage, the offender may need either faith in his resourceful throw or a stepladder. The staircase is more reliable in this regard, but it will definitely attract attention.

How to avoid it:

Install cameras in such a way that they fall into view of each other. If they try to close or break one camera, other cameras will help to fix it.

When you may need to delete recordings from a surveillance camera

The recordings made by the surveillance system have to be deleted for completely different reasons. They can depend on both the legislature and the personal attraction of the owner. For example, we have to clean the recordings from the recorder because of our own needs, because in this way we free up space for the next filming. In the case of cameras for tracking, almost the same.

Here are some reasons why people tend to delete footage:

• Limited media space.
• There is a need for previously captured files.
• Corrupted / damaged records.

Everything is extremely simple: in the first case, it all depends on the memory card (or the second media) and its size, in the second the need for files is lost, and in the third case such materials get spoiled during the shooting itself. Yes, that happens too. Why store damaged and low-quality records?

Camera wires shorted

There are two wires connected to the camera. the power cable and the signal cable. If the conductors of the power cable are shorted to each other, then the fuse of the power supply will blow, and all cameras will be disabled.

How to avoid it: Use a multi-channel power supply. When the fuse for one camera blows, the others will continue to work.

How to remove from DVR or MicroSD card? How to remove from DVR or MicroSD card?

Removing footage from your surveillance system is possible, but it depends on many factors, the main one being whether you have administrator-level access to the security system.

It is almost impossible to erase any recordings from the DVR or SD card if you do not know the password of the recorder.

However, there are several solutions and tIPs that you can use to delete recordings from your NVR, DVR, micro SD card and computer surveillance system.

In this guide, we have summarized several methods for deleting surveillance footage.

Note right away that you do not need to manually delete anything in order to free up space for news.

Many users think that you need to manually erase the footage to make room for new recordings. After the HDD or memory card is full, there is a need to erase the footage or recordings.

By default, all security systems automatically loop the footage, erasing old recordings and recording new ones. Thus, the surveillance system will automatically loop the recording.

But if you need to erase only individual frames, for example, that which you DO NOT want someone to get access to them, then you can erase this data. True, there is one thing, but for this you need to have access parameters to the system.

If you do not know the credentials, then this is very difficult to do. The only way out is to format the hard drive or memory card, but in this case all data will be lost.

Let’s say someone invades your home, can they remove them from your surveillance system without your knowledge? Unfortunately yes. True, most often the attacker does NOT tinker with the deletion of data, but disable the registrar or take it away with him.

Hacking the same control system is possible only if it is installed by a non-professional. These days, high quality IP cameras from famous brands are protected by SSL encryption, thus protecting the recordings.

In addition, surveillance systems are often configured so that an alarm is triggered if someone tries to tamper with it. A professional surveillance system will send notifications to the owner’s phone containing. Photos and other information about the alarming event. You will immediately know that something will happen at your home or at another guarded object.

Modern surveillance systems can also use cloud storage to save footage. This means that even theft of the registrar, the attacker will not give anything, because the owner of the surveillance system will be able to get access to the records stored in the cloud and identify the attacker from the filmed materials.

But back to the issue of deleting information. If you are the owner of a surveillance system and have access to it, that is, a password and login, it will not be difficult to remove it from the hard drive or SD Card.

If you need to delete individual files or specific data in the right time frame from the memory card, you need to remove the micro SD card from the IP camera and insert it into the card reader. From there, you can delete any unnecessary entries using your computer or laptop. After that, insert the micro SD card back into the security camera.

Accessing the camera from a computer depends on the model number. However, the procedure is pretty much the same regardless of the manufacturer. To format and therefore erase from surveillance cameras from a microSD card, you need:

Log in to the IP camera. Enter the IP address of the camera in IE browser, enter the administrator username and password. If you don’t know the IP address of the camera, use the manufacturer’s scanner to find it.

Go to the “Settings” section of the cameras. Find the Storage section. Select the microSD card and click the “Format” button to delete all recording files from the microSD card.

Some surveillance cameras, especially the new ones, which are supported by the built-in phone apps, allow you to format the micro SD card directly from the app.

Just enter the camera through the app, go to settings and find the button “Format SD card” as shown in the image below.

To erase the recording on DVR or NVR, the fastest way is to format the hard disk of the DVR. In this case, all data stored on it will be deleted.

The procedure is almost the same regardless of the device manufacturer. You should Access your DVR or NVR directly (or through a web browser), find the hard disk partition and click on the “Format” menu item, as shown below for the Amcrest system. For this:

Connect DVR or NVR to monitor or TV with HDMI or VGA cable.

Log in to the registrar with an administrator account and password. Go to the “Configuration” or “Settings”.

Find the Storage section. Format the hard drive to delete all or images from the security camera.

Formatting the hard disk does not affect other recorder or camera configurations such as motion detection, email settings, scheduling, masking, etc. That is, after formatting the hard drive, everything will remain the same.

But if you need to remove the separate from the DVR and not format the hard drive?
Alas, this is often not possible. Most surveillance manufacturers do NOT offer this feature. It is impossible to delete individual in a specific time range stored on the hard disk of the recorder.

Wasted time trying to delete individual files from the NVR hard drive. As we mentioned earlier, just format the entire hard drive and everything will be deleted. This is the safest and best way. Everything else is a waste of time.

But sometimes after formatting the disk by accident or by mistake, you need to recover the erased data. That’s quite possible.

When you format the hard drive, data still remains on the hard drive, but is marked for overwriting. That is, the hard drive is empty and ready to be refilled.

There are companies that can recover deleted, overwritten or formatted data from CCTV hard drives. It can be expensive, but if you need it, it’s doable. Or you can try to boot from your hard drive using the free GoPro software to recover erased data.

For example, Stellar Photo Recovery software can help you recover your lost CCTV. This software can recover photos and files lost due to accidental deletion, damage or formatting of internal or external hard drives or SD memory cards.

To recover erased data, you must:

• Install the hard disk of the recorder into the computer and the reader from the hard disk.
• Run Stellar Photo Recovery.
• In the main menu of the program, select “What to restore”.
• The next step is to select the location from where you want to recover (you must select the hard disk of the recorder). Click Scan to start the scanning process.
• When the scanning process is complete, you will see the Scan Completed Successfully Dialog Box displaying the scan results such as the number of files found and the size of the data. You can preview and preview the recovered data and see if there is anything of value. If you do NOT see the ones you want in the list, select the “Deep Scan” option at the bottom to perform a deeper scan of your hard drive.
• Select the ones you want. Right click and select Recover.
• Specify the location where you want to save. Then click “Save”.

You can also recover from formatted hard drives using MiniTool Photo Recovery and MiniTool Power Data Recovery. These are powerful tools that can recover lost and deleted data from hard drives, USB drives and almost any type of drives or directories that can store and lose data.

Install the Minitool recovery program on your computer and follow the steps.

• Install (or connect) a hard drive or microSD card to your computer, and then launch the software. Note. You may need a hard driver reader to connect to your computer.
• Select the target disk (which is the hard disk of the surveillance system) and click “Scan” to start the process.
• Check the list “Your. Which need to be restored “.
• If there is something of value, save the selected along the specified path.

How to forcefully delete a recording from a security camera?

To delete information from the media, you need to figure out on which device it is still stored, since they can be completely different.

When recording to a memory card

The archive can be stored on a memory card connected to a digital surveillance camera, on a card reader with a memory card, on an external hard drive or on a regular flash drive. Most often, the USB connector is used for connection.

With a registrar

often than others, the record is located on the hard drive of the registrar. You can erase it Go to the DVR menu (you will need a local connection and access to the DVR) or by connecting to the DVR from a computer (you will need data for authorization). In both cases, data will be required (login / password from the registrar). After connecting to the recorder, everything is simple, you need to go to the hard disk management menu, format it.

When connected to a computer

Recording can be carried out on a hard disk (into a computer), respectively, you need to get physical access to it or data for remote connection.

How long are recordings from surveillance cameras kept?

The maximum recording time depends on several factors and is determined solely on an individual basis. The record retention period is influenced by:

• Industry interests.
• Legal requirements.
• Internal control regulations.
• Time of obtaining permission to view.
• The presence of recurring events.

For example, in some organizations there are special services that estimate employees’ work by UAH. Since suchs are carefully and regularly viewed, there is a need for their long-term storage.

What if you need to keep recordings from surveillance cameras for a long time? The only way out is to copy all the archived files to a flash drive. It must be stored away from places with high humidity and sources of electromagnetic radiation.

When sending data to the cloud

The recording archive can be stored in the cloud. To erase records from the cloud, you will need information with which you can enter the Cloud service (password and login).

Detailed step-by-step instructions for deleting recording from surveillance cameras

Today, one of the main components of security systems is the surveillance system. Records from surveillance cameras are kept for a certain time, since the archive is often used to clarify various controversial situations. However, not everyone knows how to delete a recording from a surveillance camera. The way to remove it depends on the storage medium.

Are cameras always recording?

Today, in practice, surveillance only with recording is used almost everywhere, since without this function the surveillance system is NOT effective.

Observation with recording is slightly more expensive than without this feature.

But is the installation of surveillance, especially if it is hidden from prying eyes, always a legal procedure? In some cases, such activity can be regarded as a violation of human rights provided for by the constitution, and then very serious punishment is provided for such a violation.

For this, different methods are used: announcements over the speakerphone, information signs or visiting rules, where, in addition to written information, there is a picture of the camera that is understandable to everyone.

The use of cameras allows you to fix and prevent various offenses, violations of the regime of objects, attacks on personal safety, etc. The information obtained in this way is considered in court as evidence.
