A. WV-CLR920 (220-240 V AC 50Hz)
1. Plug the AC power cord (supplied as standard
accessory) into the AC Inlet Socket.
2. Connect the AC power cord to a 220-240 V AC 50
Hz outlet.
Notes:
• Connect the power cord firmly.
• The power cord should be long enough for panning
and tilting.
If the cable is too short, the power cord plug may
be pulled off the camera when the camera pans or
tilts.
B. WV-CLR924 (12 V DC/24 V AC)
The WV-CLR924 has an AC/DC compatible input termi-
nal. The 12 V DC or 24 V AC power supply cord can be
connected to this terminal. The camera detects the
power source automatically.
1. 12 V DC Power Supply
Connect the power cord to
the AC/DC compatible
input terminal on the rear
panel of the camera.
