Common Problems and Solutions for Installing Home Monitoring System

1. The transformer used in the home monitoring system is abnormal


Reason analysis: the power adapter is unstable, causing the power supply system to malfunction.


Solution: Replace the power adapter and buy a regular matching power adapter. Besides that, when purchasing the power adapter, you are supposed to choose qualified security camera suppliers.


2. The line of the home monitoring system is abnormal


Cause analysis: Too many line connectors or poor line contact.


Solution: Detect the faulty line of the home monitoring system and replace it.


3. Several horizontal interfering signals with the same interval appear on the display of the home monitoring system


Reason analysis: Because the impedance of the video coaxial cable is not 75Ω, it causes an impedance matching mismatch. Or the power supply, grounding system problems, signal attenuation caused by line aging, line interference, etc.


Solution: Impedance mismatch use the method of "start-end series connection resistance" or "terminal parallel connection resistance" to solve. Check the grounding of all equipment again and replace the aging circuit.


4. The home monitoring system suddenly appears wood-grain-like interference signals


Reason analysis: The quality of the video transmission line is not good, especially the poor shielding performance parameters, and the wire resistance is too large, resulting in excessive attenuation of the data signal. Or because the power adapter of the power supply system is not "clean".


Solution: Replace the video cable of the high-definition surveillance camera or add a cable sleeve; the power adapter problem can be solved as long as the entire home surveillance system is a regular power supply or an online UPS power supply system.
