[ Pacific Security Network News ] Monitoring equipment plays a vital role in the security industry, monitoring equipment failure caused by incorrect equipment power supply, and troubleshooting methods! 1. Equipment failure caused by incorrect power supply.
The power supply is incorrect. There are several possibilities: the power supply line or the power supply voltage is incorrect, the power is not enough (or the wire diameter of a certain power supply line is sufficient, the voltage drop is too large, etc.), and the transmission line of the power supply system is short-circuited, open, and instantaneous. Pressure and so on. In particular, damage to the equipment due to power supply errors or transient overvoltages occurs. Therefore, in the system debugging, before power supply, we must carefully check and check carefully, and should not be taken lightly.
The probe is connected to the alarm input of the picture splitter, and the alarm signal of the probe will drive both the alarm host and the picture splitter. In this case, there is often a problem of insufficient driving ability. The phenomenon is that although the picture splitter can alarm, but the input alarm signal is weak and the work is stable, so that the image picture of the camera corresponding to the alarm signal is instantly converted to a full screen on the monitor. But it is lost (can't hold), and the image on the monitor is still multi-screen before the alarm.
To solve the above problem, the signal of the alarm probe is connected with the picture splitter or the video switching host through a dedicated alarm interface box.
2. Since some devices (such as cameras with three variable lenses and pan/tilt) have many links, if the processing is not good, especially if the line connected to the device is not handled well, there will be open circuit, short circuit, and line. Poor insulation, mis-wiring, etc. cause damage to equipment and performance degradation.
In this case, the analysis should be carried out in a calm manner based on the fault phenomenon, and it is judged that the fault phenomenon occurs on the lines due to the problems of the connection of the lines. This will narrow the scope of the problem. 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.
