Heater Unit
When the heater unit (sold separately) is used, the camera can be used outdoors in low-
temperature environments down to -30ºC (-22ºF). The heater automatically turns on when
the temperature inside the camera falls below about 10ºC (50ºF), and turns off when the
temperature inside rises. The condensation fan alleviates the problem of clouding
(condensation) caused by temperature change in the camera dome caused. Note, however,
that significant condensation caused by sudden temperature change cannot be completely
alleviated.
Important
• The camera image may be influenced when the heater unit is turned on and off.
• Before installing and removing the heater unit, be sure to turn off the camera. The heater
unit is hot while it is turned on. Disconnect the connector from the camera, and wait for
the heater to cool down before removing it.
• When the heater unit is installed and use is started in environments of -10ºC (14ºF) or
below, normal images may not be obtained immediately after the camera is started up.
In this case, wait for the camera to warm up (about 2 hours or more) before turning the
power on again.
• Use 24 V AC or POE to deliver power to a heater unit.
