Output voltage is the same as input.

Hi,
as far I know, Passive PoE means DC voltage presence on pins 4,5 (+) and 7,8(-).

802.3af/at, means voltage presence on DATA pins 1,2 and 3,6 or in our case, pins 4,5 (+) and 7,8(-). af/at refers to the voltage-wattage provided by/to the port.

Again,as far I know, there are two type of poe cameras. The ones that support passive poe (usually low end devices) and the ones that support active poe (both low and hi-end devices).

If your camera is passive poe, it will work. BUT BE AWARE THAT THE WATTAGE POWER OF THE mAP IS NOT DESIGNED FOR FEEDING CAMERAS. This means, that a typical camera with IR enabled will need about 10-12 Watts, while:

Max out per port output (input < 30 V) 0.5 A
Max total out (A) 0.5 A
Max power consumption 5 W


Even if your camera is 5W, you can not feed it directly from mAP, in a long-term application, you'll burn out the output of this tiny router. Also keep in mind the previous posters advice: Output voltage is the same as input.

In conclusion, use an external POE injector, is this is possible.

Wish you all the best, happy Christmas time!
A small addition to the above, output of the mAP could be up to 2 Volts lower than the input. You sould use a 14V source.
