So I have a few of theses DS-2CD2042WD cams and hooked them up to the NVR and had then all working then started to run wires and lay out the system, did a factory reset on the NVR and now the cams can't seem to get picked up, its a plug n play Hikvision DS-7716NI-SP/16, I have done the whole hold down the reset button while plugging in for 10 seconds all the way to 30 seconds, but cams just are not getting picked up, can't see them with SADP only poe is the NVR might have to get a power cord to power cams one at time and see if I can see them on the LAN, any ideas what I'm missing here, just can't be this hard to reset them back to factory or maybe it is..:sad2:
