Set up tripwires on my Dahua CCTV?

[snuff_sed]

I would be really grateful if some kind person would give me some advise about setting up the trip wires on my CCTV.

The white light on one of my cameras is not coming on either.

I'm not sure you can set up 'trip wires' easily on a camera system. Do you mean electronic detection and notification? Something like 'intruder' or 'line crossing' - or do you mean actually fitting sensors on the ground to link into your camera system? You'll have to give model numbers (cameras and recorders) of what you've got fitted for more detailed advice.
