OPTIONAL HEATER UNIT
■ Optional Heater Unit WV-CW3HE
● Introduction
Installing this heater unit enables the camera to operate under in a low-temperature environment of –30°C (–22°F).
The heater turns on automatically when the temperature inside the camera drops below +10°C (50°F) and turns off
when it rises.
A small fan inside the unit will minimize condensation on the surface of the dome cover caused by changes in ambi-
ent temperature unless temperatures change too rapidly. The fan will stop when there is no possibility of condensa-
tion.
● Precautions
• This product should be installed and connected by qualified service personnel or system installers.
• Do not use the same 24 V AC power source supplying the power to the camera for the heater unit. Connect
another 24 V AC power source to the heater unit. If the same power source is used, turning the heater on and off
may disturb the camera images.
• When servicing, pay attention to high temperature on the surface of the unit. Disconnect the harness and wait
until it cools.
• When you install the camera in a low-temperature location and start operating it, it may take time (around 30 min-
utes) for the inside of the camera to warm up. Cut power once then supply power again.
