We have had a batch of V2020-WIR-360 Cameras where a problem can develop that leaves the camera with no images in either the web browser or VMS. Although this problem can occur if an Insufficient PoE supply is connected the firmware can also be at fault.
Firmware camC6P_01.00.0048 should be updated immediately if found on a camera BEFORE this fault occurs. Unfortunately if the fault is already present then upgrading the firmware will not resolve and a return to base is required.
The latest firmware can be downloaded from here: https://www.vicon-security.com/software-firmware/v2000-360-multi-sensor-camera-software-downloads/#v2020-wir-360-multi-sensor-camera
As of Feb 2023 current firmware is camC6P_01.00.0059
