What does security monitoring mainly do?

Control part: This part is the core of the security monitoring system, which completes the digital acquisition of analog video surveillance signals, MPEG-1 compression, monitoring data recording and retrieval, hard disk recording and other functions. Its core unit is the acquisition and compression unit, and itsChannel reliability, computing processing capacity and convenience of video retrieval directly affect the performance of the whole system.

While monitoring video capture, it is combined with a variety of anti-theft accessories to realize the anti-theft trigger alarm.

Security monitoring refers to the all-round and multi-angle monitoring and management of public places, organizations, enterprises, etc. in order to ensure public safety. It can transmit the monitoring image to the monitoring room for real-time monitoring by installing monitoring equipment. At the same time, the monitoring image can be recorded and archived for subsequent viewing.

Monitoring can be used as forensic evidence. To put it bluntly, anti-theft alarm monitoring, building intercom, community parking lot, gates, etc. can all be summarized as security. Security is an industry, and monitoring is only one of them, that is, an electronic high-tech preventive measure for people's safety.

and record it through the video recorder. At the same time, the alarm system equipment alarms illegal intrusion, and the generated alarm model is input into the alarm host, and the alarm host triggers the monitoring system to record the video. The security monitoring system mainly includes: video monitoring, preventive alarm, building intercom, smart home, background music, access control attendance parking lot gate.

Design is the key to the decoration effect. Drawing drawings should reflect the internal structure clearly, the nodes are clear, and the dimensions are accurate. All drawings should be signed and approved by Party A. In-depth construction site should be supervised on whether the construction personnel conceives construction according to the design. The drawing changes should be jointly studied with Party A to change the drawing instructions. Construction can only be carried out after Party A signs.

Security monitoring system installationWhat are the requirements

1. What are the requirements for the installation of the security monitoring system? What are the basic equipment selection requirements? First of all, determine whether to install a monitoring card on the existing computer or use the embedded hard disk recorder as your monitoring host.

2. Install the camera: Install the camera in the selected position as needed. Make sure that the camera can provide clear images and a wide field of view. Connect the camera and monitor: Use the correct type of cable to connect the camera to the monitor. Make sure the connection is stable and test whether the image transmission is normal.

3. When installing the camera, do not use a DC regulated voltage power supply that exceeds the power supply specifications allowed by the camera; indoor camera should not be installed outdoors, so as not to cause damage to the indoor camera; outdoor installation is strictly forbidden to aim the camera at the sun and luminous objects with strong light sources, otherwise it will cause image blur and Produce a halo.

4. The equipment of the security system is required to be installed in a clean air-conditioned room and on the standard rack of 19. There should be an appropriate space between the equipment, and a fan with forced ventilation should be used.

What does a complete monitoring system include?

1. Remote expansion system: IP monitoring, remote monitoring, network monitoring, video conferencing and other technical exchanges.

2. The hardware composition of the security monitoring system usually includes the following aspects: camera: installed in the area that needs to be monitored, and the monitoring is completed by capturing images. Video server: used to manage and store images or videos taken by cameras.

3, 1 camera part The camera part is the cutting-edge part of the TV monitoring system, which is the "eye" of the whole system. It is placed in a certain position of the monitored place, so that its field of view angle can cover the entire monitored parts.

4. CRT monitor, LCD monitor, TV wall, hard back projection, ordinary projection screen, VGA monitor.

5. Monitoring front-end: camera, lens, shield bracket, supplementary light, vertical pole.Camera monitoring transmission: BNC head, video cable, power cable, signal amplifier, anti-interference device, lightning arrester, optical terminal. Monitoring back-end: hard disk recorder, hard disk, matrix, screen splitter, picture splitter, operation desk, TV wall, cabinet.

6. It is the front camera; the transmission is some lines; it is the control keyboard; the monitor is usually hung on the wall; the memory is the hard disk recorder. The encoders and decoders you mentioned will only be used when analog video is converted into digital.

How to use the security monitoring system

Set up remote access: If you need to remotely access the monitoring system through mobile phones or computers, you need to set up network port mapping or use cloud services. Improve other accessories: Install other accessories, such as infrared sensors, door and window sensors, etc., to enhance the function of the home security monitoring system.

What are the requirements for the installation of the security monitoring system? What are the basic equipment selection requirements? First of all, determine whether to install a monitoring card on the existing computer or use an embedded hard disk recorder as your monitoring host.

Classification. According to the network cameras used, the monitoring system can be divided into analog system and digital system. Generally speaking, these two systems can meet the needs of home monitoring. The most troublesome thing about building a home security monitoring system by yourself is wiring.

Usually, we have two control methods - analog control and digital control. Analog control is an early control method. Its console is usually composed of a controller or analog control matrix, which is suitable for small local security monitoring systems. This control method has a low cost and a small failure rate.

♂Monitoring system Monitoring system is one of the most widely used systems in the security system. From a technical point of view, the development of video surveillance system is divided into the first generation of analog video surveillance system (CCTV), to the second generation of digital video surveillance system (DVR) based on "PC + multimedia card", to the The third generation is completely based on the IP network video surveillance system (IPVS).

Yes. The surveillance camera can be used without a network. The monitoring system does not mean that it must be connected to the network, but it is more convenient to access the network. The monitoring system is usually composed of a set of equipment such as cameras, video recorders, monitors, cables, etc.

Security monitoring system configuration recommendation

1. Security monitoring system mainIt should include the front-end part, transmission part, control part, TV wall display part, anti-theft alarm part, and system power supply part.

2. In small security monitoring systems, our most common transmission layer equipment is video cable and audio cable. For medium and remote monitoring systems, we often use radio frequency cables and microwaves. For remote monitoring, we usually use the Internet, a cheap carrier.

3. Classification. According to the network cameras used, the monitoring system can be divided into analog system and digital system. Generally speaking, these two systems can meet the needs of home monitoring. The most troublesome thing about building a home security monitoring system by yourself is wiring.

4. The total number of wiring racks required depends on your network, the number of phone points, and the specifications of the wiring rack you use;It is not suitable for sharing. The security system is generally networked separately.

5. The simple one is the entrance and exit of the villa, the exit of the garage, and the surrounding walls. About 4-8 cameras and an 8-way hard disk recorder, a monitor, and a 500G hard disk are enough.

What parts does the security monitoring system consist of

The hardware composition of the security monitoring system usually includes the following aspects: Camera: Installed in the area that needs to be monitored to complete the monitoring by collecting images. Video server: used to manage and store images or videos taken by cameras.

The security monitoring system is mainly composed of these three parts: front-end part: mainly composed of black-and-white (color) cameras, gimbals, protective covers, brackets, etc.Transmission part: use coaxial cables, wires and multi-core wires to transmit audio, video, control signals and AC and DC power supply, etc. by overhead, buried or along the wall.

We divide the entire security monitoring system into seven layers according to the different functions of each part of the system - performance layer, control layer, processing layer, transmission layer, execution layer, support layer and acquisition layer. The composition of the monitoring system - the performance layer performance city is what we feel most intuitively, which shows the quality of the whole security monitoring system.

Hello: The video security monitoring system is composed of the following points image acquisition - infrared camera (outdoor rain gun type, outdoor rainproof tube type, 360° gimbal, indoor hemisphere, etc.) signal, power supply transmission - power supply (AC 220V, 48V, 24V, DC 24V, 12V Wait).

The video security monitoring system generally consists of four main parts: front-end, transmission, control and display records.
