How to choose the equipment for the video surveillance system

1. Determine the monitoring area: Before installing the monitoring system, we need to determine the size and shape of the monitoring area.Select monitoring equipment: Select the appropriate monitoring equipment according to the size and shape of the monitoring area. Install monitoring equipment: Install monitoring equipment according to the installation instructions of the equipment.

2. When the monitoring equipment is equipped with two monitoring cameras in front and behind, if the rear camera does not play a big role, it is not recommended to buy it. Whether there is a night vision function? The monitoring should also have a night vision function, so as to avoid the monitoring equipment becoming blind at night.

3. Home monitoring requires equipment: network camera, storage device, monitor, router, power adapter, etc. The network camera, as the front-end of the monitoring, provides high-definition video input. The image can be transmitted to the remote client through the network for real-time monitoring and video recording.

4. Selection of camera clarityChoose whether the camera of the network high-definition monitoring system is 1 million, 1.3 million, 2 million, 3 million pixels.

5. Therefore, if the project you undertake is these application sites, you can consider whether to choose the product in terms of cost.

What does a complete video surveillance system include? What is the most important part? Help

[Answer]: The video surveillance system is generally composed of four main parts: the camera subsystem, the image transmission subsystem, the control subsystem and the display recording subsystem.

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

The monitoring system consists of 5 major parts, including camcorder (front-end equipment), transmission system (network cable, optical cable, video cable), terminal equipment (embedded video recorder, PC,...), record registration, etc.

Front-end: camera transmission: including: power cord, variable voltage power supply used to provide power to the camera, video cable or twisted pair cable plus transmitter, used to transmit video signals. Storage monitoring: If you use a computer, you need to install a video capture card in the computer.

The TV monitoring system consists of five major parts: front-end monitoring equipment, transmission equipment, back-end storage, control and display equipment.Back-end equipment can be further divided into central control equipment and sub-control equipment. There are many configurations of front-end and rear-end equipment, and the connection between them can be realized through cables, optical fibers, microwaves and other ways.

The digital video surveillance system inputs analog video signals, compresses the image after digitization, and then performs storage, transmission and related control.

How about the high-definition video surveillance system

1. It can take pictures of scenery, scenery, flowers, moving objects, people, and observe whether the picture is clean, whether the noise size and color are natural and realistic.

2. Practicality. The system should take into account factors such as local environmental conditions, monitoring objects, monitoring methods, maintenance and investment scale, so as to meet the needs of the normal operation of the monitoring system and social public safety management.Scalability.

3. OK. High-definition image quality and remote access: Jiatu monitoring system provides high-definition video image quality, which can capture clear details and ensure the quality of the monitoring picture. Jiatu Monitoring also supports remote access function, which can view real-time monitoring images anytime and anywhere through mobile phones, tablets or computers, which is convenient to grasp the situation of the monitoring area in real time.

4. On the same device, the resolution of 2k is better than that of 720p, and the picture of 2k is clearer and more delicate, and you can see more details. At the same time, when shooting videos, the memory occupied is also relatively large.

In the network video surveillance system, how many 720P high-definition images can be solved by the best decoder?

1. The gimbal decoder mainly modulates the 485 bus control signal, including gimbal rotation, pitch, lens focus, magnification, aperture, etc. The video decoder of the network surveillance TV wall mainly decodes the images transmitted by IP cameras or encoders.

2. The decoder has a maximum of 12 channels, and a maximum of 12 channels of images are divided. The number of decoders is determined according to the number of display devices. If there are no more than 8 display devices, an 8-way decoder is enough.

3. The decoder can solve 4-way monitoring. The D300 HD 4K decoder supports 4 channels of 4k video, or 16 channels of 1080p30 HD video decoding output at the same time. If the decoder only supports 8 monitors, it can usually use a computer with software installed to control the splicing effect, but this device is relatively expensive.

4. The embedded hard disk recorder itself has a 485 communication interface, and there is no need to add an RS-232 to RS-485 pass-through protocol converter. The communication between the hard disk recorder and the decoder is a one-way communication. The data is sent by the hard disk recorder until the decoder receives it, and the decoder does not send any data to the hard disk recorder.

What is a video security monitoring system?

1. The video security monitoring system is to facilitate the relevant information in the monitoring area. Real-time monitoring of video recordings can be extracted at any time, so that it is well documented. The video security monitoring system in the security prevention system is different from the general industrial TV or civil closed-circuit television (CCTV) system.

2. The video surveillance system is composed of real-time control system, monitoring system and management information system.

3. The security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and forms an independent and complete system from camera to image display and recording.

4. Video surveillance system (VSCS) video surveillance & control system uses video technology to detect and monitor forted areas and display and record on-site images in real time.

5. Computer monitoring can be literally understood into two parts: "supervision" and "control". Among them, "supervision" refers to obtaining information mainly through the network: while "control" refers to the method of operating remote computers through the network, restarting, shutting down and other operations on remote computers, including remote The terminal computer carrys out the daily setting work.
