ok so have 2 x IPC-T5442t-ZEB that have suddenly both stopped detecting ivs tripwire in B&W mode only? not changed any settings however they did get rebooted after a power cut.

tried rebooting everything, poe switch, cam etc but logic says its within the camera as daytime onvif are sent to bi as normal

would a super low manual shutter be the problem, if running custom shutter 0ms - 7 ms, so the image is quite dark?

How dark? Can you post a pic?

It all depends on ambient light and/or IR. I run 0-8.33 on a lot of cameras...a few even faster
