[ Huaqiang Security Network News ] The current monitoring system occupies a large proportion in the security industry. When the monitoring system just enters the debugging phase, there may be such a failure phenomenon, such as: failure to operate normally, the system does not meet the design requirements. Technical indicators, overall performance and quality are not ideal. These problems are inevitable for a monitoring project, especially for a complex, large-scale monitoring project. The following gives you an analysis of the reasons and solutions for the monitoring system not running. 
1. Equipment failure caused by incorrect power supply. The power supply is incorrect. There are several possibilities.
The power supply line or supply voltage is incorrect.
The power is not enough (or the wire diameter of a certain power supply line is not enough, the buck is too large, etc.).
Short circuit, open circuit, instantaneous overvoltage, etc. of the transmission line of the power supply system.
In particular, equipment damage caused by power supply errors or transient overvoltages may occur. Therefore, before the system is commissioned, it is necessary to carefully check and check before power supply, and should not be taken lightly.
2. The camera and pan/tilt of the three-variable lens do not rotate/the lens does not move. There are many links between these devices, and there are often problems such as disconnection, short circuit, poor insulation between wires, miswiring, etc., resulting in equipment damage and performance degradation.
It is particularly worth noting that the camera with the pan/tilt is very common due to the all-round movement, which leads to the disconnection and breakage of the connection. Therefore, the connection between the equipment and various lines that pay special attention to this situation should meet the requirements for long-term operation.
3. Quality problems with the equipment or components themselves.
In theory, quality problems can occur with various equipment and components. However, from the experience point of view, the quality problems of the products themselves are mostly on the decoder, electric cloud platform, transmission components and other equipment. It is worth pointing out that some equipments may not have the problem of being unusable in quality as a whole, but from some technical indicators, they fail to reach the indicators given in the product manual. Therefore, the necessary sampling tests must be performed on the selected products. If it is a product quality problem, the best way is to replace the product, and not to disassemble and repair it.
4. Problems caused by improper adjustment of equipment.
For example, the adjustment of the back intercept of the camera is very detailed and precise work. If not carefully adjusted, there will be problems such as poor focusing or defocusing during various operations of the three variable lenses.
Whether the position of some switches and adjustment knobs on the camera is correct, whether it meets the technical requirements of the system, whether the decoder code switch or other adjustable parts are set correctly will directly affect the normal use of the device itself or affect the normal performance of the entire system.
5. The problem of incorrect connection between the device (or component) and the device (or component) will generally occur in the following aspects:
The impedance does not match.
The communication interface or communication method does not correspond.
Insufficient drive capability or exceed the specified number of device connections.
The power supply line or supply voltage is incorrect.
The power is not enough (or the wire diameter of a certain power supply line is not enough, the buck is too large, etc.).
Short circuit, open circuit, instantaneous overvoltage, etc. of the transmission line of the power supply system.
