7.8 Connecting power

The camera operates on 12/24 VDC, 9 W max. (allowed range: 10–30 VDC) and heaters
on 24 VDC, 25 W max. In total: 34 W.
The camera itself does not have an on/off switch. Generally, the FLIR A3xx f series cam-
era will be connected to a circuit breaker, and the circuit breaker will be used to connect
or interrupt the power supply to the camera. If power is supplied to it, the camera will be
in one of two modes: Booting Up or Powered On.
The power cable supplied by the installer must use wires that are of a sufficient gauge
size (16 AWG is recommended) for the supply voltage and length of the cable run, to en-
sure adequate current-carrying capacity. Always follow local building codes.
Ensure that the camera is properly grounded. Typical to good grounding practices, the
camera chassis ground should be provided using the lowest resistance path possible.
FLIR Systems requires using a grounding strap anchored to the grounding lug on the
back plate of the camera housing and connected to the nearest earth-grounding point.
Note The terminal blocks for power connections will accept a maximum 16 AWG wire
size.

7.9 Video connections

The analog video connection on the back of the camera is a BNC connector. The camera
also provides an RCA video connector that can be used to temporarily monitor the video
output, without disconnecting the BNC connection.
The video cable used should be rated as RG59U or better to ensure a quality video
signal.

7.10 Ethernet connection

The cable gland seal is designed for use with shielded Category 6 Ethernet cable.
