I've tried to hook up an alarm door contact to my NVR to switch to full screen on a particular channel in the event of a door being open.
It kind of half works.... I've got everything set up, but can only get it to switch to full screen using the door contact tamper switch.
Whether i set the alarm input to be N.O or NC this alternates whether it switches when the tamper switch is pushed down or released.
When the cover is fitted, tamper switch depressed, it won't switch when the magnets are separated or moved together no matter what i do.
The door contacts have selectable resistors one for tamper, one for zone and I've now ended up cutting both as per normal for my alarm, assuming it works in the same way when the cover is on and tamper switch down, magnets together would be circuit closed, move apart would be circuit open and switch the display?
Can i not use these type of door contacts with hikvision NVRS or how do i get it to work?
