What is a wide dynamic camera? What does wide dynamic camera mean?

Wide dynamic camera is a technology that allows the camera to see the characteristics of the image under very strong contrast. In some situations where the contrast between light and dark is too large, due to the limitations of the CCD's photosensitive characteristics, ordinary cameras often capture images with a background that is too bright or a foreground that is too dark. In response to this situation, wide dynamic technology emerged as the times require, which better solves this problem.

The main application of wide dynamic cameras is when the lighting environment is ideal, but the details of the target object cannot be obtained. In other words, wide dynamic technology is mostly used in places where light and dark alternate. When surveillance cameras cannot achieve low-light monitoring, wide dynamic technology needs to be used to "fill in the light."

Precautions for using wide dynamic cameras

1. The rated voltage of the wires used for surveillance cameras should be greater than the working voltage of the line; the insulation of the wires It should comply with the installation method of the line and the environmental conditions of laying. The cross-sectional area of ??the conductor should be able to meet the requirements of power supply and mechanical strength.

2. When wiring surveillance cameras, try to avoid wires with connectors. Unless connectors are not available, the connectors of the camera must be crimped or welded, and the wire connections and branches should not be subject to mechanical force. The wires controlled in the pipe must not have joints under any circumstances. If necessary, place the joints on the junction box probe terminals as much as possible.

3. The surveillance camera wiring should be installed horizontally or vertically in the building. The wiring should be protected by casing (plastic or iron water pipes, selected according to the technical requirements of indoor piping). Metal hoses can be used for ceiling wiring, but they need to be fixed securely and beautifully.

4. Surveillance camera signal lines cannot be parallel to high-power power lines, nor can they be worn in the same pipe. If due to environmental limitations, parallel wiring is required, keep it at least 50cm away.

5. The AC power supply of the surveillance camera alarm control box should be routed separately. The camera cannot be worn in the same tube as the signal wire and low-voltage DC power supply wire. The installation of the AC power supply wire should comply with electrical installation standards.

6. The wiring from the surveillance camera alarm control box to the ceiling needs to be managed and managed into the wall or protected with iron pipes to improve the anti-destruction performance of the anti-theft system. Technical requirements for indoor piping of cameras.

7. There are two types of camera cable conduit wiring: exposed and concealed. The exposed piping of the camera must be horizontal, vertical, neat and beautiful. Concealed piping requires short, smooth pipes and few elbows.
