What the device consists of

If we consider independently installed equIPment of the middle price range, designed for a certain period of autonomous operation, GSM surveillance cameras will include the following hardware groups:

  • Battery or single battery with voltage conversion circuits, power control;
  • The system of interaction with the mobile operator’s network, including the unit for installing the SIM card;
  • A separate software module that controls transmission parameters;
  • The system for accumulating archive data, both with internal memory capacity and providing for the installation of external expansion cards.

Depending on the needs, the GSM surveillance structure can be built on devices with additional capabilities. In practice, nothing new is offered in solutions for mobile networks that would NOT be offered by conventional cameras on the market.

In GSM surveillance cameras, there can be IR illumination for shooting in night mode, a rear light source compensation system, a motion detector, separate image capture modes.

Connectable GSM unit

Cameras that connect to a single processing and storage unit. preferred option for those who want to get a multi-viewpoint tracking system.

In this case, the system is built on the following princIPles:

  • A rational structure of the interaction of nodes is determined (via cable or wireless protocols)
  • A decision is made on the power supply system (a list of points where an autonomous mode is needed and cameras operating from a 220 or 12V network);
  • Selects cameras from which data will be broadcast via the mobile data network

The central GSM unit performs the following functionality:

  • Receives data from cameras via cable or wireless protocols;
  • Performs image processing (for example, combining images from several cameras into one screen)
  • Interacts with the operator’s mobile network;
  • Transfers data in accordance with the mechanics set in the settings.

With the help of such equIPment, which has a fairly affordable price, it is possible to implement any complex system.

For example, using a GSM unit and several surveillance cameras for a summer cottage with motion sensors, it is easy to build a well-thought-out and reliable structure of continuous data collection in cases of unauthorized interference.

Each PH-X2 can serve as a central alarm console, supporting up to 10 security zones, up to 24 sensors, and consoles of structural associations of security systems.

The device is configured both via direct connection and remotely via SMS commands.

Review of popular models of GSM cameras

The modern market provides all the possibilities for building GSM surveillance with the necessary functionality. At the same time, it is easy to apply one of the popular camera models.

Features of GSM surveillance cameras

In practice, any GSM camera is a standard segment device, the functionality of which is supplemented by hardware and software modules.

The features of work on mobile networks include:

  • Discreteness of image transmission, the camera broadcasts a certain number of frames per second
  • Transfer format, either via 3G communication protocols, or by sending SMS / MMS messages to a Customized subscriber number.

Depending on the system configuration, GSM surveillance can be represented both by a set of cameras, each of which is an independent device, or by a structure of recorders and a central data processing unit.

Proline PR-G01AM

Compact and handy, Proline PR-G01AM offers high autonomy, data storage, microphone and IR illumination. She takes pictures and. Provides remote access capability.

Its features include:

  • Built-in motion sensor;
  • The ability to automatically send photos and in the form of MMS messages;

You can connect to the camera directly with a smartphone, call its SIM card number. This opens access to the microphone for a quick assessment of the situation at the protected facility.

All in outdoor surveillance cameras


IP domes are very popular with network surveillance users and installers. Devices of this type have a hemispherical housing, which is ideal for installation under a porch canopy.

The main advantage of using IP dome cameras is a high degree of surveillance sampling (invisible and fast change of direction of observation, small size), which makes this device perfect for places where it must be almost invisible.

IP domes usually do NOT allow replacement of the optical system (lens) used in them. Even if the model allows for lens exchange, it is significantly limited by the small amount of housing space.

Types of surveillance cameras

Possible additional equIPment for digital cameras:

  • Built-in motion sensors;
  • Sound;
  • Speakers;
  • Microphones;
  • Alerts in case of tampering or damage to the lens.

Operating temperature range

Since outdoor cameras continue to work in frost and heat, this factor must be taken into account when choosing a device.

Usually the region in which the cameras will operate is taken into account:

  • The middle strIP and the south of Russia. the mercury column of the thermometer rarely drops below 30 ° С;
  • The Far North and Siberia. frosts are frequent and up to 50 ° С.

In the characteristic of each device for observation, such a parameter as the operating temperature range is indicated. All external devices with conventional lenses work without interference at temperatures from 50 to 50 ° C.

There are also cameras with an ARD lens, they can withstand weaker frosts up to 30 ° and heat up to 50 ° C. Still, for cold regions of the country it is more rational to choose cameras with the function of additional heating of the body and lens. This will help the device to work smoothly even in 50-degree frost.

How to increase the angle of view of a surveillance camera

If the monitoring target is located 30-40 meters from the camera, then when buying, you need to take a device with a viewing angle of up to 45 °. In this case, you can also use a camera with a viewing angle of 90 °, but then the effect of moving away from the object will take effect, which means that less details will be visible.

To combine long-range and short-range observation, you can purchase a camera that has a varifocal lens. In such a device, you can change the viewing angle. Unfortunately, their cost is almost 2 times more than in devices with a fixed viewing angle.

What are the street cameras

Feeling safe in the home and in the neighborhood is extremely important. But choosing the right observation device is difficult for many. A monitoring or alarm system is now already a standard.

This is NOT an exclusive accessory anymore, as few can afford. Installation costs are several times lower than those that can follow in case of burglary, vandalism and other troubles.

Surveillance cameras can be divided into categories:

  • Internal / external;
  • Analog / network.

By types:

  • Dome;
  • Cylindrical;
  • Swivel.

And also all types of devices can have additional properties:

  • Reinforced hull (from vandals)
  • Protection against moisture and dust;
  • Large or small viewing angle;
  • Heated body (from severe frosts).

Housing and vandal-proof

Outdoor monitoring devices are often equIPped with alarm sensors.

These sensors are triggered in cases when:

  • The lens is covered by your hand or an unnaturally static picture has been established;
  • The lens or camera body is damaged.

To protect against vandals and hooligans, there is a series of devices with a particularly durable case, which is not so easy to damage.

Any surveillance system can periodically fail, therefore, in order not to lose monitoring data, when setting up the camera, you need to select a file that is duplicated on the external information storage.

In order to remotely receive an image from the camera in real time, a recording device is installed that transmits information to the server in the cloud (where the resulting image passes through encryption and is well protected from external manIPulations).

Light sensitivity

When choosing a device, it is imperative to take into account its threshold of sensitivity to a lack of lighting. The characteristics of each device indicate such an indicator as the minimum illumination. This is the threshold below which the camera will not be able to clearly capture the events taking place around.

To determine the level of illumination, the unit is one Lux (lx), the more Lux is indicated, the better the shooting and visibility of the monitoring object.

Let’s look at an example: in the descrIPtion of the camera it is indicated that it has a sensitivity of 0.01 Lx, that is, the camera sees a picture at an illumination of 0.01 Lux and above.
Illumination less than 0.01 Lux leaves the camera blind and helpless.

What sensitivity (in Lux) is required for cameras:

  • Night, street, moon. 0.3-0.1 Lux;
  • Night, full moon. 0.05 Lux;
  • Night without the moon. 0.01 Lux;
  • Starry night. 0.003-0.1 Lux;
  • Poor visibility (dusk), illuminated at night on highways.10.00 Lux;
  • Day, outdoors, sunny weather. 100,000: 5,000 Lux;
  • Day, street, cloudiness. about 5000 Lux;
  • Covered parking, large storage rooms.75-30 Lux;
  • Huge premises (supermarket, hypermarket). about 1500: 750 Lux.

Devices with different sensitivity behave differently:

  • At night;
  • At dusk;
  • In the rain;
  • In the snow;
  • When the camera is suddenly blinded by headlights;
  • When aiming a laser beam at the camera.

Necessary equIPment for organizing street surveillance

The first step that needs to be taken is to properly prepare an action plan, which will contain all the relevant information (required number of cameras, camera type, cables, power supply, etc.). Planning begins with an overview of the territory, which will have to be further viewed by the camera (s).

The heart of the monitoring system is the recorder. a device that records from cameras, processes it and allows it to be displayed on a TV, LCD monitor or via a local network on a computer. The selection of an appropriate recorder depends on the number of cameras. The most commonly used monitoring systems. for 4, 8 and 16 cameras.

After we have selected the number of cameras and, accordingly, have determined the number of inputs required for our monitoring, let’s move on to choosing a recorder model. A variety of models are currently offered.

It is advisable to choose a recorder with maximum picture compression. The best compression so far is H.264. You can also select MPEG-4 or MJPEG compression. H.264-compressed recorders save more images to the hard drive, they have better shooting quality.

Another important property of the selected recorder is the number of frames per second, which is in direct proportion to the resolution used for recording. The value of 6 frames per second is quite enough for the protection of a small local area. it allows you to register events as they arrive.

The most popular image resolutions in analog instruments are D1 (720 × 576) and CIF (352 × 288). CIF resolution is less than D1, but usually provides write speed 4 times faster. However, it is better to choose a higher resolution, even at the expense of recording speed.

Even higher resolutions (1920 x 1080 or Full HD) are available in IP and HD-CVI surveillance devices. It is worth considering these devices, while developing a security system for the local area (office, at the enterprise).

Differences and criteria for choosing street surveillance cameras

For outdoor surveillance, ordinary indoor cameras without a protective case are not suitable. For outdoor installation, it is necessary to use cameras that have a good degree of protection against adverse environmental influences. As a rule, such cameras are marked with special designations like “IP66”, which means a high degree of protection against penetration, moisture and dust. Let’s take a closer look at all the main features of street surveillance cameras, and talk about the main criteria for their selection.

Differences between street surveillance cameras

The main distinguishing feature of surveillance cameras intended for outdoor installation is the presence of a special thermal casing, which protects the device from precIPitation, as well as from exposure to high and low temperatures.

When choosing such cameras, you should pay attention to the following characteristics:

  • IP protection degree. thanks to these figures you can find out what conditions of use the camera is designed for, we have already written about this in more detail here;
  • Operating temperature range. you need to buy the device that corresponds to the lowest and highest temperatures typical for your area;
  • The presence of a heating element. allows you to use the camera in extremely low temperatures;
  • Minimum illumination. so that the camera can keep track of what is happening both day and night, it is necessary to purchase a device with good light sensitivity, for example, for shooting at night, the device must have a min. Illumination 0.003-0.1 Lux, with moonlight. 0.3-0.05 Lux. In general, the higher the camera sensitivity, the better.

For outdoor installation, dome surveillance cameras are often used. due to the design features of these devices, it is practically NOT possible to pull the camera out of the installation site, and the risk of damage to the device by solid objects is also reduced, provided that the camera has a vandal-proof housing with protective glass.

Another consideration when choosing cameras for outdoor surveillance is the availability of automatic iris control and wide dynamic range (WDR). Due to the frequent changes in illumination even in the daytime, the camera should be able to automatically change the aperture values, and thus adjust to the current lighting in order to avoid the appearance of flare-ups, as well as a dark image. The wide dynamic range is useful when there is an uneven distribution of illumination throughout the frame, for example, with direct sunlight. With WDR, the likelihood of overexposure and darkened areas in the frame is significantly reduced, and the entire image looks even in the light level.

When shooting at night, the camera should be able to automatically switch to black-and-white mode, since in monochrome at night the sensor’s light sensitivity increases, and the amount of digital noise is reduced, and the image looks better than “in color”. Today, most cameras have a similar mode, but still, just in case, check this point with the seller when buying.

If earlier miniature cameras were available only to a select few, today the Internet is replete with offers for their sale. Wireless mini cameras can be used for any purpose, and their low cost allows even an ordinary person to purchase them. You can find out about the selection criteria and the main characteristics of mini cameras from this article:

Infrared illumination

In addition to good sensitivity for shooting at night, good infrared illumination is NOT superfluous. IR rays are NOT visible to the human eye, but they are well perceived by the camera matrix, and when the backlight is on at night, the camera can see and record what is happening as in the daytime. Today, almost every camera is equIPped with IR illumination, so you should pay attention to its power, range, and also the angle of view. in some models of cameras, the illumination angle may NOT coincide with the angle of view of the cameras, as a result of which an illuminated white spot may appear in the middle of the frame, when how there will be a lack of lighting around the edges. Also, recently, cameras began to be equIPped with adaptive backlighting. the device independently determines the level of illumination of the scene, and automatically adjusts the backlight power depending on what is happening in the frame.

Sometimes the power of the built-in IR illumination is not enough for good illumination of the entire area of ​​the territory, in this case, independent infrared projectors are used, with which you can achieve better lighting. You can read about them in this article.

What else to look for when choosing an outdoor camera?

In addition to the above points, it is necessary to take into account the angle of view of the camera. Before buying, it is advisable to decide on the locations of the cameras, as well as the areas that each camera will control. If you want to get only a general view of the site, then you should look at devices with a wide viewing angle. from 90 °. In the event that you need to control a certain area of ​​the site, or any static object, or the entrance door to the apartment, you can opt for a camera with a smaller viewing angle.

Focal length. In general, you should decide on the distance to the object of observation. The entire site, or just the front door, as well as what you want to see on the record. the intruder’s face, or the very fact of penetration. The smaller the angle of view of the lens, the smaller the observed area and the better the picture. A camera with a telephoto lens can be hung high as it can monitor what is happening from a long distance. A device with a short throw lens will need to be hung lower.

If you are in doubt about which angle of view will be optimal for you, you can take a closer look at cameras with a varifocal lens and the ability to manually adjust the focal length during installation, or read this article, which describes this problem in detail.

Recording resolution. The last thing to consider when choosing a street surveillance camera is its resolution. Not so long ago, devices with Ultra HD resolution were released, but we would not advise you to purchase these devices yet, due to the fact that at this resolution the camera is capable of recording a stream at a much lower speed. The standard recording speed is 25-30 frames per second, while ultramegapixel cameras are capable of recording at speeds from 5 to 20 fps depending on the resolution. The best option for today is to purchase 1-3 MP cameras. they practically DO NOT differ in cost, and the image quality in them is almost equally good.

AHD cameras. Not so long ago, the so-called AHD cameras appeared on the market, which have practically replaced analog surveillance cameras. These cameras transmit the signal over the same coaxial cable, but their resolution is already much higher than the old analog counterparts, and can reach 2MP or more. They can also be used for outdoor installations and are usually slightly less expensive than IP cameras.

Other tIPs for choosing

The purchase of a ready-made outdoor surveillance kit, or each camera separately, is a rather serious and expensive purchase, so you should be very careful about their choice.

Here are some more tIPs to help you make the right choice:

So, we told you about the main criteria for choosing an outdoor surveillance camera, and tried to set out as much useful information as possible so that you no longer have any questions. If you have additional questions, or you think that we have NOT described any significant points. write in the comments, we will definitely answer them!

How to choose outdoor surveillance cameras

There are a number of technical requirements for outdoor security complexes used at medium and large-scale facilities, the most basic of which are listed below:

High resiliency. The equIPment must be made of high quality materials and rigorous assembly technology. An important factor is the length of the equIPment service life declared by GoPro and the guarantee for its trouble-free service.

Surveillance equIPment must operate 24 hours a day, 7 days a week. It is desirable that the warranty for the equIPment in this mode of operation is at least 5 years. This will facilitate service maintenance, because cameras are often located at a distance of several meters from the ground level, and their replacement or repair requires the involvement of specialized equIPment.

EquIPment resistance to aggressive environmental factors. To fulfill this requirement, specialized casings (thermo-, Hermetic casing), visors are used.

The ability to work in any light. EquIPment for outdoor use should perform its function at any time of the day, while the image quality obtained from the cameras should be sufficiently clear (see Surveillance camera with IR illumination).

In addition to security tasks, outdoor recording systems can be used for other purposes, such as commercial. Recreation parks administrations can identify and document the most passable places and routes on the territory, after which they can offer advertising space for rent to those who wish, or they can supply a vending machine with drinks.

At the entrance to the parking lot, surveying is often used to count the number of cars entering and leaving, as well as to determine the number plate. Thus, outdoor surveillance informs the operator about the amount of free parking spaces.

Technical requirements for commercial street equIPment remain the same as for safety.

Types of outdoor surveillance cameras

EquIPment for recording a signal is usually classified according to several criteria, but first of all it is necessary to determine: what tasks are set for the hardware complex, and what criteria the recording device must meet.

Systems are usually divided into:

  • Outdoor (when controls are located outdoors);
  • Internal (when control elements are located directly in the room).

According to the above-mentioned classification, different requirements are presented to the cameras, because they each solve their own set of tasks. This article will focus on recording mechanisms for street analysis.

An outdoor camera or a camera for street surveillance is a control device with special characteristics that is protected from environmental factors (wind, precIPitation, temperature drops).

Street surveillance cameras are usually divided according to the type of housing into the following types.

Cylindrical. This type is designed as a cylinder. The length of the device varies on average in the range of 8. 30 cm without casing and bracket. These are the most common outdoor enclosures. Typically a bullet camera is attached to a wall using a bracket. The outer part of the system is rather bulky. this is the main disadvantage.

The cylindrical format is not suitable for installation on buildings where the appearance of the facade is important. The pluses of cylindrical cases include a solid assortment of models and manufacturers, from inexpensive brands of Chinese GoPro, to leading European and Taiwanese manufacturers of security equIPment.

Dome. The device is hidden under a glass dome. As a rule, they use durable, anti-vandal materials; the dome of such a device is difficult to break or leave cracks on it.

Dome cameras are made into the increasingly popular Fish-Eye (“Fisheye”) model.

Panoramic cameras replace up to 4 standard devices.

Cubic. Cameras in this type of housing The most compact. They are rarely used for outdoor security. The use of a camera in cubic housing in outdoor conditions is practiced, for example, if the required control area is not large, and the device itself is hidden under a canopy or behind glass (see Mini cameras).

A special case of this type of cameras is a vehicle recorder. The size of the camera allows it to be installed on the windshield, while the recording device does NOT interfere with the driver’s or driver’s view.

Type of shell mount type appearance
cylindrical using a bracket, preferably to the wall. Ceiling mount possible.
Dome Mainly to the ceiling, it is possible to mount to the wall with or without a bracket.
Cubic body fixed with a bracket in any position.

In practice, there are also frameless cameras, which are a motherboard and a lens, usually they are purchased by security system installers for mounting hidden systems.

Axis Communications

One of the leaders in the sale of outdoor surveillance equIPment is the Swedish company Axis Communications, which produces IP cameras under the Axis brand. They are the pioneers of digital surveillance systems and recording cameras.

According to authoritative publications, Axis Communications is considered the technological leader of the security systems market worldwide.

Manufacturers and models

Nowadays, almost all manufacturers of fixation equIPment produce outdoor cameras. This is due to the constantly growing demand for these models in the security systems market. Consider the models of 3 global manufacturers of equIPment for security and control.

Outdoor surveillance cameras

It is impossible to imagine a surveillance system without its main element. a camera. After all, they are responsible for recording events that fall into the field of view of the lens.

Wireless outdoor cameras

The main difference between this type of recorder and previous types is wireless data transmission. For such devices, you only need to connect the power cable and configure the network. The most common options for the execution of wireless control devices can be considered Radio channel, 3G and Wi-Fi cameras.

Radio channel. The surveillance system consists of one or more recording devices and a radio receiver and recorder. The signal from the camera to the receiver is transmitted via a radio wave; physically, the device must be connected only to the power supply. The disadvantages of this system are the insecurity of signal transmission. Such a system is not suitable for government sites. Pros. system availability and ease of installation.

Wi-Fi technology. The information transfer rate depends on the number of cameras connected to the modem and the quality of the transmitted image. The pros and cons of Wi-Fi surveillance systems are the same as in radio channel models. For example, a Wi-Fi signal can transmit images within a radius of 300 meters in open areas, and within a radius of 10 meters in areas with obstacles.

3G and 4G cameras. These models are equIPped with high-speed signal transmission technology from the recorder to the Internet. The advantages of this wireless signal transmission include: broadband access to the network (up to 3.6 Mbps); global network coverage (the ability to transmit a signal to any distance).

3G and 4G equIPment is suitable for large facilities such as a stadium, highways or an airport. Also, users can use GSM cameras in the case when their objects are located far from each other, while combining them into a single surveillance system due to cloud services.

Outdoor 3G cameras with such streaming are not suitable for private homeowners or small business owners, since the high cost of a ready-made system using 3G or 4G technology will be a significant cost item for a security system of a small facility.

Types of outdoor surveillance cameras

By the type of signal transmission, cameras for outdoor use are classified into analog and digital (IP-cameras) transmitting via wired and wireless channels.

Analog outdoor cameras. Suitable for compact surveillance systems. The princIPle of operation of this type of technology is the conversion of the luminous flux into electrical signals that are transmitted to the server or displayed (to the operator’s monitor).

The pluses of analog recording devices include their relative cheapness and ease of setup (you hardly have to configure it). To minus. “analog” is an outdated technology, since this type of signal transmission is the ancestor of surveillance.

Another disadvantage of this technology is the lack of built-in analytics and the complexity of installation. In analogue security systems, audio transmission requires a separate cable from the camera to the recorder. Application: small parking lot or courtyard in a residential building.

Digital outdoor cameras. Increasingly, IP technologies are used for outdoor installation of surveillance systems. Since they are able to solve a wider range of tasks, in comparison with the “analog”.

The princIPle of operation of IP systems is based on the conversion of a light signal into a digital stream, thanks to a built-in encoder with a light-sensitive matrix. The disadvantages of digital technology include the complexity of setting up the complex.

The firmware interface is not always user-friendly. There are many possibilities in digital equIPment, without specialized skills in setting up and installing systems, the user will NOT be able to correctly configure the operation of the equIPment.

When switching from analog to digital systems, the user will have to spend more money and time.

Despite the listed disadvantages, digital systems have more advantages over their “analog” competitor.

These systems are capable of recording in widescreen mode. On the market of surveillance systems Models with a resolution from 0.3 to 20 Mpix are presented, such recording tools can monitor an entire street or intersection, while not missing out on small details without losing image quality.

The technology of signal transmission of IP-equIPment is carried out by 1 cable from the recorder to the computer processing the received information. This makes equIPment installation easier.

In addition, it is possible to detect the movement of objects in the field of view of the lens and perform analytical calculations. For example, some models are equIPped with people counting, motion detectors or smoke and fire detectors.

Digital recording devices can be combined into a system with an FSA or ACS, when a certain situation develops, the barrier will automatically rise, the gate automation will work or a signal will be sent to the operator panel in an incident or by means of SMS messages to the owner of the facility (see GSM burglar alarm).
Images from IP cameras are broadcast in real time in the local network and the Internet (see p2p surveillance camera).


The manufacturer of outdoor analog cameras is Acumen. This Taiwanese brand has become widespread throughout the world due to the low cost of products and a wide range.

The first two models considered are suitable for modest observation systems. The Acumen Ai-SD85 model is more expensive than the previous two, has the ability to rotate the operator and has a high expansion rate. This model is suitable for professional security systems based on analog signal transmission.

The choice of manufacturer and model should be carried out based on the requirements for street surveillance cameras for a specific object and the amount of funds. Since the cost of different models, even among the same manufacturer, differs several times.
