Hi Andy, I recently bought two of your cameras through Amazon, a T5442TM-AS on Memorial Day and a T5442T-ZE on Prime Day. The AS is working well.
I set up the ZE last night using a PoE adapter - updated the firmware to 210525 and set IP addressing to DHCP. When I plugged it into my PoE switch, it began acting oddly. It initially reported a weird MAC address (in Apple's assigned block?) to my DHCP server and then after about 30 seconds reported the expected MAC. It also wasn't reachable consistently via ping or browser. It's possible that it was cycling through multiple reboots.
Would you recommend an "at" PoE switch with the ZE (mine is "af" which may not provide enough power) or do you think the camera is defective?
