Just llike the other electronic device, the CCTV cameraalso will have many many problems. Here I’d like to share with you how to solve the most common problems for CCTV Camera.
The first problem will be no signal on the monitor. If so you have to think about that if the cable connections are ok. In fact, it is the most common problem people will meet.So next time, you meet this problem, please just check them. If the connection are all right, then the problem will be a little complicated.
Sometime you will find the picture background color changes continuously. Maybe the TV system is wrong. If your TV system is PAL, but you use the NTSC system.
The other problem maybe the fluorescent lamp’s electromagnetic fileld cause the color changes. So you need reduce the fluorescent lamp numbers or increase the distance between the cameras and the fluorescent lamps.
The last possible problem is that there is no image at the night. For this the reason maybe the power for the CCTV cameras is not enough. If you use cables at 50m , and you still use the DC12V 1A power supply. Maybe the power will weak so much at the camera ens. And it can not support the IR Led work.
