    for the indoor dome cameras, if I unplug the coax and plug it back, the color show for 1 second then turn black/white. is that camera problem?

    As tom posted, shine a light at the cameras, they may sense it is too dark where you have placed them, so they are switching to night vision (black and white).

     

    I tried that and it still show black and white, the area is very bright, the weird thing is that when I unplug the black/red power cables from the transformer and plug back in, it show color for 1 sec and then back to B/W

    I found the power supply unit that has all 8 cameras connected using the coax.

    the camera that is not working and showing video loss, have to trace its wires and see why no signal.

    I have about 4-6 cctv cameras connected to a DVR, having some issues:

     

    - 2 indoor dome cameras are showing black/white> no color. not sure if its from camera itself or something else

    -1 outdoor bullet camera show video loss. not sure how to check the cables

     

    everything is wired from outdoor to dvr. is there a power that connect all these cameras placed somewhere or just the coax will push power? if so maybe i need to check attic and see if thats where power is located.

     

    any advice much appreciated

    thank you
