Several characteristics of analog cameras

Analog cameras, the entire video surveillance system is divided into front-end video capture devices, mid-end transmission processing devices and back-end display viewing devices. The analog camera we are talking about belongs to the front-end video capture device. The analog camera output is an analog video signal. The analog video signal generated by the video capture device can be converted into a digital signal by an encoder and stored in a computer. The video signal captured by the analog camera must be converted to a digital mode by a specific video capture card and compressed before it can be converted to a computer.

Analog camera features 1, ease of use analog cameras: closed-circuit, can only monitor the internal, can not monitor remotely, according to 'Star Network Ruijie'.

2. Practicality Analog Camera: Video data can only be stored locally or remotely, and it is easily destroyed by criminals.

3, integrated analog camera: analog camera and DVR (DigitalVideoRecorder means digital video recorder, if only to literally understand, it does not specify whether the recording media is a tape or a hard disk.) Connected, the number of DVR has a certain limit, After the DVR is full, the cost of the hardware will increase as the number of cameras increases.

4. Install an analog camera: Connect the coaxial cable to each camera and connect it to the control platform, video recording device, and display device. Each new route must be rewired and no ready-made network is available.

5, remote analog camera: only view the image locally for management.

6. Extensible analog cameras: It is very difficult to expand the work. Each analog camera needs a special cable. When long cables are used, it will affect the image quality.

7. Cost analog cameras: Coaxial cables are very expensive, and the commonly used standard coaxial cable of RG59750hms is 30% to 40% more expensive than high quality cable. Each analog camera needs a cable. If there are many cameras, many morning cables must be purchased and the money must be spent on the installation and deployment of these cables.
