Night Vision Issue

i need a solution, i install AHD and TVL outdoor camera with a central power of 30A, 18 channel, i have two cameras connected to each channel, the problem now is during the day the camera is working fine, at night the camera is not showing any image, when you go close to the camera you see night vision IR light on, but no image display at night, but during the day the camera will display image. i have change camera thinking may be is the night vision of the camera is bad, still is the same.

thanks

Hi. Not enough power for each camera.

Why are you connecting two cameras to each output ??

Cam needs 1amp if with IR

2 X 1amp =2amp connected to 1.5amp output.

Also if you are two up on each output that is 36 cameras

Not a good install ...... 1 power failure takes out your full system

You will need more power supplies and also along with the camera amps you will need to list distance of each camera and size of power cable used.
