There have been multiple reports and multiple Vicon Support Tickets opened for power issues when using unsupported injectors with Vicon Multi-Sensor model V2020 and V2032 series Cameras.
When Vicon Multi-Sensor Cameras are used with POE Injectors, the Vicon VPOE-INJ-60BT (Manufacturer Planet) or VPOE-INJ-90BT-A (Manufacturer Altronix) Injector should be used.
If the camera is detecting a BT power connection, you should see it in the camera GUI, as seen in the following screenshot.
Also: If the switch has LLDP it could report to the camera an insufficient power supply even though an injector is being used. The switch does not know the injector is there and will tell the camera how much power it will have without the injector. To overcome this issue, you have to turn off LLDP or Cisco's equivalent which is CDP.
