5.3. Installation

The camera has a 1/4” thread insert on its top and bottom side for mounting the camera to a tripod, wall

or ceiling with a corresponding mount.

5.4 Commissioning

• First, connect the power supply to the power terminal on the rear panel of camera

• Second, plug the power adaptor to the main supply

• The camera is ready for operation

5.5. Power Supply Connections

The camera can work with either 24VAC or 12VDC, dual voltage power. It does NOT require the

polarity-matched connection for 12VDC supply. Primary and secondary grounds are completely

isolated to avoid the possible ground-loop problems. Its wide operating voltage range of 10.5V-30V

for DC and 12-28.8V for AC gives extra flexibility at the installation.

6. Start up

When the camera is powered properly, it starts up by initializing the internal parameters and the

filter switch mechanism. The filter switch unit repeats IN and OUT at each power up and just

after RESTORE FACTORY SETTINGS.
