Does anyone know if the 12VDC camera connector can be used as an accessory power source from a Hikvision camera when it is receiving power from POE?

It does put out 12VDC, center pin positive when POE powered.

How much current can be safely drawn from the 12V camera connector?

It would be very handy to use this connector to power an auxiliary IR illuminator. .
 
no it does not..

Sounds like the 12VDC connector floats to the camera power supply voltage, but can't supply any current because it would have to go in reverse through a diode.
It would be interesting to watch the output voltage as the load increased. But if someone has already tried this, it's not worth the time to test again.
Reverse diode leakage currents are in the 1 microamp range. Not enough to be useful for a peripheral.
 
even if you took the diodes out the voltage regulation and power conditioning would be designed for the needs of the camera; and not an external peripheral like IR.. a microphone maybe, but if you want more than a few mA then your going to have to bring your own regulator.. ie cut the traces and jump 48vdc source into the plug.
