Video line mode: camera-video line-terminal processing equipment
Optical fiber transmission is selected only because it is too far away, or it is suitable for optical fiber transmission when the number is too large and quite concentrated.
There are 28 points in a community, which is not much. You can use video cable directly or optical fiber.
The significance of optical fiber lies in the small attenuation of video transmission, strong anti-interference ability and large data transmission.
In practical application, there is little difference between them. It is best to use optical fiber to facilitate future expansion, while the video line is relatively stable, but it is not convenient to increase points in the future.
Generally speaking, residential projects can be satisfied as long as there is stand-alone software. You can search for sharp-eyed video surveillance guards, which are compatible with many hardware manufacturers and are free!
The community is used for monitoring, and the video is optical fiber. You can't take the open line. How about going underground?

How does going underground affect the video? How deep should we dig? What should I pay attention to?

One hundred years ago, the French writer Hugo said: Sewers are "the conscience of the city".
The conscience of weak current system integration industry lies in wiring.
In residential construction, it is best to take weak underground passages, such as communication pipes.
When crossing the road, if it is necessary to break the road, the depth of trenching should not be less than 100CM. Assuming that the width is 30CM, the pavement should be broken at least 90CM, so that this section can have better mechanical performance when it is restored.
When the line passes through the green belt, the digging depth should not be less than 70CM.
Stay away from strong electric and magnetic equipment.
Construction according to such standards requires Party A to have sufficient budget funds, otherwise there is no way to standardize it.
The monitoring of a residential area has just been connected with optical fiber, and only indoor monitoring of ordinary video lines has been done before. Now it's outdoor, and you need to connect with optical fiber, but you won't connect with optical fiber. There are always 24 leaders in the community, only 16 is used for the time being, and more will be added later. Friends who do community monitoring come to help, mainly what equipment, several core optical fibers, several videos ... mainly what equipment, several core optical fibers, several video lines, transmitted to the control room through an optical cable, and added later. Now it's outdoor, and you need to connect with optical fiber, but you won't connect with optical fiber. Friends who do community monitoring, come and help. There have always been 24 leaders in the community, and now only 16, which has just been connected to the community monitoring, is used temporarily and needs optical fiber connection. Previously, only ordinary video lines were used for indoor monitoring.
