Audio Input
The mic input on the camera module follows the computer industry de facto standard for mic inputs on PCs. The
physical connector is a 3.5mm stereo audio jack. As wired, it will work with an ordinary electrets mic sold for PC
use. We have recommended two configurations for interfacing a mic with the camera depending upon application
requirements. The LOCAL mode is the out of box configuration where the camera module is connected to a low
cost electrets mic in close proximity to the enclosure. The electret mic and its connecting cable must be electrically
floating to prevent noise and hum as a result of ‘ground loops’ We recommend a cable length of 1meter or less..
Any length longer than this will result in noise interference with the audio.

Power Requirements
Power can be supplied in two alternative ways:
•
Power over Ethernet (PoE): Both power and data are connected using a single cable, plugged into the
Ethernet port of the camera. The PoE supply equipment must be compliant with IEEE 802.3AF.
•
Direct DC Input: Use only a UL/CSA
‐
approved LPS or NEC Class 2 power source with a 12V DC 1A AC
adapter (not supplied). It must be connected to the camera via the 12V jack. This connector is a 2.1mm
positive centre jack.
If using an external power supply, note that use of power in
excess of 12V DC may damage the camera
and void the warranty.
