Ptz surveillance camera control program. Concept of PTZ video camera

PTZ - the camera has a robotic mechanism with a built-in electronic-mechanical video surveillance control drive, which controls the rotation and tilt of the device. PTZ – abbreviation (Pan Tilt Zoom) means that the camera is controlled remotely, and the camera itself has a zoom function. The optical zoom remotely changes the angle and field of view of the lens (increases/reduces the observed object). The cameras are controlled using a remote control or special software/hardware (if the equipment is connected to a network protocol).

Automation of tracking

An innovative hardware program is installed in the PTZ camera firmware. Through this software, the modulation of pixels in the image is controlled, which is transmitted and then drives the device. The function of tracking (tracking/rotating) an object, due to movement, changes the pixels and therefore the device focuses on the center of their oscillations. Next, PTZ estimates the distance at which the tracking object is located and its size. When a moving object leaves the field of view of the video equipment, the device returns to its original position or to the one that was previously programmed when the initial setup was carried out. This procedure will begin again when the camera registers other changes.

Kinds

• Analog CCTV cameras. After digitization (processing by a digital processor) of the resulting image, a special signal is sent to the electrical converter. It, in turn, modulates these signals into analog (PAL / NTSC). The device is connected to a video server or DVR recorder. To organize control of the equipment during installation, another special cable is included. The main disadvantages of such video surveillance equipment are the unsatisfactory resolution of the resulting images, as well as their deterioration during the transmission of a special signal.
• Digital IP CCTV cameras. The processed image is transmitted via IP/TCP protocol in digital form. This data is sent to the IP recorder or IP server (video). Control along with data transmission is carried out via a single cable. Higher image resolution is achieved when compared with analog cameras.

Design versions

1. Outdoor dome hemisphere or Speed ​​Dome. Exclusively all components of the device (electronics and mechanics) are placed in a sealed hemisphere. Thanks to this placement, the penetration of dust and moisture particles into the housing is completely prevented. This also helps to increase the level of protection against vandals. The temperature regime during operation of such devices is: -50° - +60°C.
2. Outdoor dome spherical PTZ. A similar hemisphere model, but the difference is more powerful infrared illumination. It has a high degree of fault tolerance, that is, it excludes exposure to moisture, dust and is protected from acts of vandalism. The operating temperature of the equipment ranges from -40° to +60°C.
3. Rotary housing PTZ (indoor). The moving units of the camera are open, so the mechanical elements interact with external environment. As a result, there is low protection from dust and moisture. The operating temperature of the device ranges from 0° to +55° C.
4. Spherical dome PTZ (indoor). Designed for installation indoors in buildings and structures, as it requires the absence of low temperatures, as well as high humidity and dust.
5. Outdoor robotic PTZ is a hybrid of an electric drive and an outdoor camera. At the moment, the dome camera has replaced the robotic camera from the market. Accordingly, the latter is rare.

Areas of use

• premises;
• open area.

Thanks to built-in heating of internal and external components, as well as a sealed housing, the dome camera can be used in areas with any maximum temperatures and various climatic conditions. Some models can be used in places where human presence is impossible due to exposure hazardous factors. For example, at nuclear and chemical industry. And thanks to optical zoom (approximation), devices are actively used for video conferencing and negotiations.

PTZ control is also popular in television production. Used on professional studio cameras for robotic control.

Setting procedure

PTZ cameras are used in two modes:

• fixed;
• mobile.

Working in a fixed (stable) video surveillance mode, the device (even dome technology) is always statically aimed at the controlled surveillance area. As a rule, without controlling the camera position (a rotating function is present), but with possible remote reconfiguration, if necessary.

When working in mobile video surveillance mode, the direction angle of the device periodically changes to expand/narrow the point of view and detail the necessary objects.

As a rule, customers have a technical specification or a rough idea of ​​where the camera should be, what zones it should be aimed at, the frequency and route of movement. All video surveillance and control options are individual.

After installing video surveillance, you need to configure the camera according to technical specifications. It doesn’t matter whether it’s a PTZ camera or a static one, dome or regular, outdoor or indoor – the setup process is almost identical in all cases. Setting up analog cameras is similar to digital IP cameras. It’s just worth noting that digital IP cameras can also be configured through a video recorder and using software/hardware that is preinstalled on the computer.

Setup and programming is usually done by CCTV installation specialists.

Procedure for setting up an analog PTZ camera

1. Connecting the camera to the recorder.
2. Information setting of operating modes.
3. Selecting the required surveillance channel.
4. Individual settings for each PTZ surveillance channel.
5. Indication of the control protocol (depending on the one supported by the camera).
6. Selecting the data transfer rate.
7. The task of stop bit parameters (transmitted to separate information).
8. Choosing a method for detecting errors when transmitting information.
9. The task of the device’s IP address for the recorder (connection is established through it).
10. Specifying the mode and schedule of camera movements.

For remote control of IP PTZ video surveillance cameras, the following are used:

• wireless infrared remote control;
• mouse;
• special software (which adds the ability to automatically control cameras);
• wired USB remote control;
• control via Ethernet interface (for high-speed data transmission by cameras);
• remote control keyboard with 3D joystick.

For equipment of control and video surveillance systems, for any territory, the most the best option there will be a PTZ dome IP video camera. It is the dome IP camera that is resistant to aggressive environments, has convenient controls and allows you to monitor even the largest area without leaving blind spots. The dome camera and its various variations are the most popular type of PTZ cameras.

PTZ cameras are an offshoot of compact video surveillance devices. The developers of this equipment have raised miniature security cameras to a new level by equipping them with more efficient automatic and, in some cases, robotic systems. intelligent control. Partially similar technologies were used in the first generations of video surveillance systems, but modern solutions differ noticeably in a number of parameters, which is confirmed by the example of a PTZ camera. What does this mean in practical use? First of all, these are broader possibilities for controlling camera settings, and in remote mode. In addition, the creators of PTZ models pay attention to the basic characteristics of shooting, allowing you to obtain high quality images while maintaining the modest size of the camera itself.

General information about PTZ cameras

This is a non-standard camera, the main difference of which is the presence of a built-in electronic-mechanical drive. Moreover, the matrix itself, which ensures recording of the video stream, is quite consistent in its characteristics with traditional compact cameras for video surveillance. The features are determined by the drive with a robotic control principle, which, by the way, can act as a separate part - an element of the package. However, the latest models of this type are different and internal device. Optical zoom, in particular, allows you to change the viewing angle that the PTZ camera captures. What is this from a consumer point of view? This essentially means variable optical zoom out and zoom in on the target object. Signals to control the drive mechanism and internal sensors can come from the remote control, or can be generated by controllers that interact with the computer. That is, through the software, the user can configure fully automatic operation of the camera.

Main characteristics of the camera

The number of pixels is the main indicator of the quality of work for all types of such cameras. The simplest versions are provided with 0.3 MP matrices, and high-tech ones with 5 MP modules. The number of recorded frames per second is usually in the range of 6-30 units. Of course, in assessing image quality one cannot do without resolution. PTZ devices- HD cameras, for example, confidently support the 1920x1080 format. At the same time, the outdated VGA matrix at 640x480 remains relevant. In security systems, the use of such modules is often justified. But if the characteristics described above fully fit into the set of qualities of conventional video surveillance cameras, then PTZ has noticeable advantages in the speed of rotation and increase in focus. Thus, optical zoom can be 36x, and digital zoom 18x. As for the turning speed, in modern models it reaches 400 °/s. Also, advanced modifications are equipped with 3D positioning technology.

Areas of application of PTZ equipment

Experts identify two areas in which the operational capabilities of such cameras are most advantageously revealed. This security systems security and video communication in conference rooms. In both cases, users appreciate the flexibility of the hardware in terms of control and virtually unlimited possibilities for physical installation of the equipment. It is important to note here the wireless connection systems that a modern PTZ camera supports. What does this mean during operation? Wireless communication technologies practically eliminate the need for the user to connect cables to the device. From the point of view of camouflage, this is the optimal solution, since an attacker will have less chance of detecting signs. And vice versa, the operational operation of the camera’s rotating mechanics will allow you to track what is happening in the room with the most advantageous positioning.

Types of video camera designs

Manufacturers produce cameras of this type in several variations. The most widely used is a PTZ camera in the form of a hemisphere. This variety is called Speed ​​Dome and is highly fault-tolerant. The design itself, thanks to its geometric shape, minimizes the risk of dust and moisture particles getting under the housing.

Another option is a spherical design, which is in many ways similar to hemispherical cameras. Such models are usually equipped with powerful infrared illumination and means of protection against vandals. In general, PTZ dome cameras are designed in such a way that all mechanical components inside have minimal chance of direct contact with the environment. This advantage is especially evident in the cases of street models, which deserve special attention.

Features of street models

Operating video surveillance systems outdoors requires taking into account a number of additional factors. Among them are the nuances of ensuring communication between the camera and the control panel, the organization of the power supply system and issues of protecting equipment from external influences. As for protection, cases usually receive a thermal casing with dust- and moisture-proof insulation. Some models are additionally equipped with a heater and ventilation system, which provide the ability to cold start at peak negative and positive temperatures. Power can be provided directly or from batteries. By the way, the use of uninterruptible power supply sources also justifies itself. Even a standard PTZ camera setup allows you to automate the process of switching to backup power in case of unstable network power supply. Communication, in turn, is also organized either directly via cable or via wireless technology using a radio module.

Analog and digital models

In analog models, the resulting recording is automatically processed by a digital processor. Next, the material is sent to an electronic converter, in which conversion occurs again, but in reverse mode. The communication connection of such equipment is provided by coaxial wires. The disadvantages of models of this type include low resolution, which does not allow you to count on high-quality images when shooting at long distances. Digital PTZ CCTV cameras also provide pre-treatment signal in the processor, after which the material can be transmitted via the TCP/IP protocol in the initially specified format. The main advantage digital models It is precisely a high-quality “picture”, since in terms of communication and mechanical equipment, analog devices in some cases turn out to be a more reliable solution.

Camera control

In addition to setting basic shooting parameters, PTZ cameras provide a lot of control options during the actual use of the device. When installing a camera on site, the user can pre-program it with hundreds of preset positions. For each mode, a whole set of position parameters is assumed, including the angle, zoom level, etc. Some models also allow you to assign individual automatic scanning scenarios. For example, an outdoor PTZ camera is the most developed in this regard, since it has to cover large areas, including long-range views. Remote control, in turn, allows for tilt correction. For this, a telemetry remote control is most often used.

Manufacturers of PTZ cameras

High-tech segments are quickly filled with products from large manufacturers. In this case, the situation is somewhat different, since the most successful developments are demonstrated by lesser-known companies. The leading position is occupied by the Axis PTZ camera, modifications of which are focused on both specialized and universal video surveillance tasks. Also worthy of attention are offers from Dahua, Geovision and integrated solutions from Optimus. From the largest worldwide famous brands Samsung engineers have mastered PTZ technology well, although due to the high cost this product not so popular compared to analogues from the above-mentioned manufacturers.

Conclusion

The interest of consumers themselves in video surveillance systems of this type is not so expressed. Despite the obvious technological breakthrough of individual solutions, these products still occupy a separate narrow niche. Manufacturers also understand this, striving to develop new options and functionality that a PTZ camera could, in principle, have. What does this mean in context general development segment? At this stage, technologists are relying on optimizing the communication interaction between the camera itself and the control complex. In practice, this will mean simplifying the means of organizing communication between the individual components of video surveillance systems, and at the same time, a tighter convergence of camera mechanics and software.

In some areas of modern life, PTZ cameras have gained popularity. From the decoding of the PTZ abbreviation, we can conclude that such cameras provide the ability to control the driving mechanism (Pan/Tilt/Zoom - panning/tilting/zooming). Thus, you can control PTZ cameras remotely, manually adjust its position with the ability to rotate 360° while behind the monitor screen, and, if necessary, enlarge the image. This feature of this type of device allows you to replace several static cameras with one rotating camera. You can also program the device to automatically respond to changing events in the frame.

Controlling PTZ cameras

The ability to control PTZ cameras is realized due to the presence of an electromechanical drive in the devices, which provides the ability to rotate and tilt the PTZ camera. Also, such cameras are equipped with a built-in optical zoom, which allows you to remotely adjust the focal length of the lens. The mechanism is controlled remotely using a digital camera connected via a network protocol, or via a remote control for analog cameras.

There is nothing complicated about manually controlling cameras - the operator sits at a computer screen and, using a joystick or keyboard, rotates the camera in the required direction.

The automation of modern PTZ cameras works on the principle of reacting to changes in pixels in a certain area of ​​the frame. In other words, the device program, when movement occurs in the frame area, notices this, and when the object moves in space, it turns the camera after it, and when the movement stops, it stops the camera. After the moving object has left the viewing area, the camera automatically returns to its original position. It is also possible to configure sensitive areas of the frame, in which, when movement occurs, the automation will be triggered. You can make insensitive those areas in which movement occurs constantly, and in principle is not a significant reason for triggering the sensor, for example, an enclosure with a dog.

Most PTZ cameras have an automatic territory patrol function, which allows the camera to automatically move along a given route. Depending on the model, you can set from 8 to 200 presets.

The auto-flip function ensures that the camera unit automatically rotates 360° when it reaches a mechanical limiter, after which the camera continues to move along the specified route.

Other characteristics

The optical magnification of the lens of analog PTZ cameras can reach 36x, digital – 22x. The maximum digital zoom is 18x.

Like fixed cameras, PTZ devices can be equipped with various event sensors that react to movement, noise, etc. The standard function of automatically switching to black and white shooting mode when darkness falls (day/night function) is also implemented. Among other things, all dome and hemispherical devices are equipped with built-in IR illumination diodes for.

Execution options

PTZ CCTV cameras, like static ones, differ in their housing design. In addition to being divided into outdoor and indoor, PTZ cameras come in case, dome and hemispherical types, but dome video capture devices have gained the most popularity due to their reliability due to the location of the entire mechanism under the “dome”. The anti-vandal housing of dome PTZ cameras reliably protects them from all kinds of mechanical influences and adverse operating conditions.

With the dome camera, you can adjust the field of view at a right angle downward and perform 360° panning. Due to the design features of spherical dome cameras, they all have powerful IR illumination.

Hemispherical outdoor cameras, like dome ones, have high protection from environmental influences due to the location of all parts of the moving mechanism inside a sealed hemisphere.

The mechanism of housing PTZ cameras closely borders on the environment, so their protection from atmospheric influences is very low. Because of this feature, the use of enclosure PTZ cameras is limited to indoor spaces in the absence of unfavorable conditions such as high humidity and dust.

Types of PTZ cameras

Like any other cameras, PTZ has a clear division into analog and digital devices.

Today it is most advisable to use analog PTZ cameras. The choice in favor of this type of device can be made based on ease of connection, as well as high image resolution (HD, Full HD), comparable to IP video surveillance devices, which old analog cameras cannot boast of. The ease of connecting AHD cameras is determined by the ability to transmit video, audio, and control of the rotating mechanism via one coaxial cable, when for simple analog devices it would be necessary to lay a separate cable for control.

PTZ IP cameras have high image resolution, and can also be directly connected to the Internet or integrated with cloud services for remote video surveillance and control of the camera’s driving mechanism from any gadget from anywhere in the world if there is an Internet connection. All signals are transmitted via one UTP cable () type 5e.

Dome PTZ IP WiFi camera IVUE-IV8513PZ

As an example of an outdoor PTZ IP camera, we take the IVUE IV8513PZ model, with a 1.3 MP matrix and a maximum recording resolution of 720p (1280x720). The implementation of Wi-Fi technology provides the ability to wirelessly connect the camera to a router to set up remote access via the Internet, access the device with mobile phone or computer. This also features WDR (wide dynamic range) technology, which allows video surveillance in difficult conditions with uneven lighting distribution. Viewing the video stream from the camera and controlling the rotating mechanism is done through a CMS program or browser interface. IVUE IV8513PZ has a built-in motion sensor, IR filter and IR illuminator with a range of up to 10 meters. Operating temperature range from -30 to +50°C. The cost of the device at the time of writing is about 21 thousand rubles. By the way, the price range of almost all PTZ street cameras is approximately equal to or starts from this figure, with the exception of some models.

Scope and features of application

Thanks to the rotating mechanism, you can use one PTZ camera to provide control over the entire territory. Today, this type of camera is widely used in the security systems of stores, large shopping centers, banks, schools, in general, wherever a 360-degree view of the facility’s territory and the ability to instantly enlarge the source of an alarming event are needed.

Most often, to achieve maximum efficiency of a video surveillance system, PTZ cameras are used in conjunction with fixed video capture devices, when static cameras are constantly “watching”, and PTZ cameras are activated if a quick response to an extraordinary event is necessary to obtain decent image detail through optical zoom.

Based on the installation location, PTZ CCTV cameras can be used both indoors and outdoors. are equipped with a special sealed casing that protects the device from low and high temperatures, precipitation, moisture and dust. A heating system is built into the body of some outdoor cameras, which ensures uninterrupted operation of the device even in severe frosts. Therefore, when choosing cameras for operation in low temperatures, it is necessary to pay attention to the operating temperature range. For most types of outdoor PTZ cameras, this parameter ranges from -50 to +60°C.

If you have a PTZ camera selected in the client application (version 7.3 or later), then an icon of crossed arrows will appear in the corner of your video window; clicking on it will open the control panel for your camera.

PTZ video cameras are cameras equipped with an electric motor and a rotating mechanism, operating in IP and analogue video surveillance systems.

A distinctive feature of the popular PTZ camera is the ability to control this mechanism. This is indicated by the abbreviation PTZ, which can be deciphered as panorama - tilt - zoom. This camera is controlled remotely. The operator, sitting in front of the monitor, has the ability to rotate the camera up to 360 degrees, change its tilt, and also zoom in using a varifocal lens. Such a wide ability to manipulate the camera allows it to replace several cameras that have a static position and transmit images from only one visible view.

How to control a PTZ camera

Actions aimed at controlling the PTZ camera are provided by an electromechanical drive built into it. With its help, the camera is able to rotate and change the angle of inclination. The camera has a built-in optical zoom that allows remote control focal length lens. The mechanism itself can be manipulated using specialized programs or through the DVR interface. It is also possible to control the camera using a special PTZ remote control. The latter, by the way, is the most convenient solution, but requires additional costs.

It is very easy to manipulate the PTZ camera in manual mode. In this case, the operator, sitting at the computer, performs turns and tilts using keyboard buttons or a joystick.

The principle of automatic camera maneuvering is its response to changes in pixels in the camera's coverage area. That is, through the installed program, the camera reacts to movement in the tracking focus. If the fixed object moves, it turns and tracks its movement. If the object stops moving, the camera also stops. The camera stops and returns to its original position when the captured object leaves its working area. The program can be configured in such a way that the camera will not respond to areas where regular, non-hazardous movement is recorded. An example of such constant movement is a dog enclosure.

Another indisputable advantage of many PTZ cameras is the ability to program them to automatically patrol a given area. In this case, the camera automatically tracks the perimeter, moving along a programmed trajectory. Various camera modifications will allow you to program from 8 to 200 presets.

The available “auto-flip” function allows the camera to automatically rotate 360 ​​degrees until it reaches a mechanical stop. The mechanism then continues its “walk” along the programmed perimeter.

Additional Features of PTZ Camera

For analog PTZ cameras, the optical zoom capability of the lens can be up to 36x, in digital cameras– 22x. Digital zoom reaches a maximum of 18x.

Similar to fixed video tracking mechanisms, PTZ cameras can have sensors that respond to motion, noise effects, etc. PTZ cameras have a day/night function, which allows you to automatically switch to black and white images in the evening and at night. In addition, cameras with a dome or spherical device are equipped with built-in IR diodes. This makes it possible to provide illumination when shooting in night mode.

Modifications of PTZ cameras

Both static and PTZ cameras designed for video surveillance may differ from each other in their housing. They are also used for indoor or outdoor surveillance. PTZ cameras are available in box, dome and hemispherical versions. Dome cameras are the most popular among customers as they are the most reliable. Safety is ensured by the chamber being closed under the dome. The working mechanism is protected by a dome device and protects it from mechanical damage and various negative natural manifestations during its direct operation.

Dome cameras make it possible to adjust its observation area downward at a right angle and program a 360-degree rotation. All cameras of this kind are equipped with good IR illumination, which can be installed due to the structural features of such models.

Hemispherical and dome rotating cameras, designed for external observation, are reliably protected from all adverse climatic conditions, since the entire working mechanism is enclosed inside a hermetic sphere.

As for case cameras, their mechanism is in direct contact with the aggressive influence of the environment, and the case does not protect their mechanism from the adverse effects of precipitation and other natural manifestations. Therefore, case-mounted PTZ cameras are mainly used for internal monitoring and in rooms where there is no dust or excessive air humidity.

Types of PTZ cameras

PTZ cameras, like all similar devices, are divided into 2 types: analog and digital.

Among analog PTZ cameras, cameras that deserve more attention are . These modern devices have a simple connection, high image resolution (HD, Full HD), which is compatible with an IP video tracking device, which is not observed in old-style analog mechanisms. Modern analog AHD camera easy to connect, which involves transmitting video and audio signals, as well as camera manipulation, which is carried out over a single coaxial cable. For similar older cameras, an additional cable is required to control them.

IP PTZ cameras have high resolution, and they can also be connected to the Internet or to a cloud server designed for remote monitoring. This also makes it possible to control the camera from anywhere on the map using any gadget with Internet access. All types of signals are transmitted by one UTP cable type 5e.

An example of a PTZ IP camera for street surveillance is the Hikvision DS-2DE7174-A model, with a 1.3 MP matrix and a maximum resolution of 1280x720. Wi-Fi allows you to provide wireless connection cameras with a router and via the Internet, you can control the device through any gadget or computer. The WDR (wide range) function provides high-quality video in unusual low visibility conditions. Reading information and controlling the device is carried out or. This camera is equipped with a motion sensor, an IR filter and a backlight with a range of up to 10m. The operating temperature scale for the camera ranges from -30 to +50 degrees.

Application area of ​​PTZ camera

The rotating mechanism of the PTZ camera is capable of providing control of the entire territorial area. This camera is used in cases where it is necessary general review around the area and within a few seconds zoom in on the scene of the incident. Such objects are shops, banks, educational establishments and other public facilities.

The greatest effect is achieved by the combined use of static and rotating cameras. Static cameras monitor on an ongoing basis. In case of an unforeseen situation, a PTZ camera is connected. It provides a 360-degree view of the emergency site and allows you to zoom in as close as possible to determine an unusual situation. An excellent solution to this problem is the Trassir Activedom+ software module.

PTZ cameras can be used for video surveillance both indoors and outdoors. External cameras are placed in a special casing that protects them from precipitation and aggressive environmental influences, as well as from temperature changes. Some outdoor cameras are equipped with a heating system, which allows them to operate reliably even at very low temperatures. When choosing cameras, you should take into account the possible range of negative temperatures and select the appropriate models. Basically, PTZ cameras have a working temperature zone ranging from -50 to +60 degrees.
