N3x/N4x Power Supply

The N3x and N4x devices can be supplied with power via Power-over-Ethernet or via a DC supply on the GPIO port. On PoE switches the camera registers as PoE class 3 device (6,49 - 12,95 W).

DC Supply

All N31/N36/N41/N46 devices need a 24V DC Supply. N30/N35/N40/N45 additionally support supply voltages down to 12V.

Examples of possible power supplies are:

  • Connect the device to a PoE compatible switch or use a PoE injector

  • Supply 24V via a custom cable on the Binder 712 7-pin connector


  • The camera has an inrush current demand of up to 2A on connection and on opening the device from a computer. During these times the supply voltage on the GPIO port must not drop below 11V for correct operation of the camera. For seamless operation, especially with long supply wires, we therefore recommend to connect the camera to a 24V supply for sufficient voltage reserve.

  • When the camera is connected to a PoE compatible switch and voltage is also provided on the GPIO connector the power supply over PoE will be preferred.


  • N30/N35 Rev. 2, N40/N45 and N31/N36/N41/N46 cameras have a slightly higher continuous current demand to support their higher LED duty cycle. When switching from Rev. 1 cameras supplied with an external 12V source you should check if your supply wire cross sections are large enough to still supply sufficient voltage on the camera side despite the increased current.


  • N31/N36/N41/N46 cameras only support 24V DC input or PoE. Although the camera will also operate at lower voltage stable operation regardless of cable length can only be guaranteed with a 24V or PoE supply.
