CONNECTIONS
A. WV-BP550 (120V AC 60Hz)
1. Connect the AC power cord (supplied as standard
accessory) to the power cord socket of the cam-
era.
2. Connect the AC power cord to an electrical outlet
of 120V AC 60 Hz.
Notes:
• Connect the power cord firmly.
• The power cord should be long enough for pan-
ning and tilting.
If the cable is too short, the power cord plug may
pulled off the camera when the camera pans or
tilts.
B. WV-BP554 (12V DC/24V AC)
The WV-BP554 has an AC/DC compatible input termi-
nal. The 12V DC or 24V AC power supply cord can be
connected to this terminal. The camera detects the
power source automatically.
1. 12 V DC Power Supply
