Those numbers just don't make sense:
A standard fixed POE camera would be rated at about 6 Watts.
The maximum power for an IEEE 802.3af device is 15.4 Watts.
If you move up to the 802.3at POE+ standard then it is 30 Watts.
A really power-heavy PTZ speed dome with motors, wipers and built-in IR would take 60 Watts from a separate special high-power POE injector.
I don't know what is going on here - how you are seeing such high numbers.
It's an older model, we no longer have one of those on our demo system that I can cross-check with.
I have no past knowledge of Hikvision camera/POE ports being able to be turned on/off.
