Monitoring equipment power supply problem solution

Surveillance equipment plays a crucial role in the security industry, monitoring equipment failure caused by incorrect power supply, and troubleshooting methods!

1. Incorrect equipment caused by power failure.
There are several possible sources of incorrect power: the power supply line or power supply voltage is incorrect, power is not enough (or the line size of a certain power supply line is enough, buck is too large, etc.), the transmission line of the power supply system has a short circuit, open circuit, instantaneous Pressure and so on. In particular, equipment damage due to power supply errors or momentary overvoltages occurs. Therefore, in the commissioning of the system, before the power supply, it must be carefully checked and checked carefully and must not be taken lightly.

When the probe is connected to the alarm input of the picture splitter, the alarm signal of the probe will drive both the alarm host and the picture splitter. In this case, the problem of insufficient driving capacity often arises. The phenomenon shown is that although the screen divider can alarm, but the input alarm signal is weak and the workman is stable, resulting in the camera screen corresponding to the occurrence of the alarm signal is instantaneously converted to a full-screen screen on the monitor. However, it is lost (cannot hold), and the image on the monitor is still the multi-image before no alarm.

To solve the problem similar to the above method: through the dedicated alarm interface box to the alarm probe signal and screen splitter or video switching host corresponding connection.
2. Because there are many links between certain devices (such as cameras with three variable lenses and PTZ), if the handling is not good, especially if the lines connected to the devices are not handled well, there will be open circuit, short circuit and line. Poor insulation, incorrect wiring, etc. result in equipment damage and performance degradation.

In this case, the analysis should be made calmly based on the phenomenon of failure, and it should be determined on which of the lines that the connection is faulty. This will reduce the scope of the problem. It is particularly worth pointing out that cameras with pan-tilt heads have a long time due to all-round movements, resulting in disconnection and breakage of connections that are common. Therefore, special attention should be paid to the connection of equipment and various lines in this case to meet the requirement of long-term operation.
