5.5. Power Supply Connections
Camera can work with either 12VDC or 24VAC, 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 excellently wide operating voltage range of 10.5V-30V for DC and 12-28.8V for AC
gives an extra flexibility at the installation.
6. Start up
When the camera is powered properly, it starts up with initializing the internal parameters and the filter switch
mechanism. The filter switch unit repeats IN and OUT two times at each power up and just after RESTORE
FACTORY SETTINGS.
