I'm having trouble powering up some PTZ cameras using Mikrotik PoE switches and routers (PowerBox Pro, CRS112-8P-4S-IN, hEX PoE). I thought the 802.3at standard required up to 600mA of current to be available from the power sourcing equipment (PSE) but I notice that many Mikrotik products that claim to support 802.3at only provide up to 450mA per port (PowerBox Pro, CRS112-8P-4S-IN, hEX PoE), as per the official Mikrotik product specifications.
The PTZ cameras draw up to 530mA when the infrared LEDs are on and when panning, tilting, or zooming the camera, but these Mikrotik devices are only supplying up to 450mA at 48V (using the 48POW adapter).
Do these Mikrotik devices not properly support the 802.3at standard as they claim? Or am I wrong in thinking that the 802.3at standard requires PSE to supply up to 600mA per ethernet port?
Thanks!
