Day/Night
(DN Versions only)
This switch sets the light level at which the camera automatically switches between day and night
operation. Hi sets the camera to switch between day and night mode at higher light level. Lo sets the
switching point at a lower light level. The default setting is Lo.
When in Night mode, the IR cut filter is removed allowing infra red illumination to be used.
Colour Burst
(DN versions only)
The Colour Burst (CB) switch allows the colour burst component of the signal to be turned on or off.
When a day/night camera switches to night (mono) mode, the colour burst can be switched OFF
for a true monochrome signal. Note that some multiplexers/recorders detect video-loss if the colour
burst signal disappears. If problems are encountered with the multiplexer/recorder when the camera
switches to mono, try setting CB to ON. Default is CB OFF.
Lens Level
Adjust the lens iris level according to the lighting conditions.
1
Turn the Automatic Gain Control switch OFF
2
Adjust the Lens Level potentiometer so that a 1 V peak-to-peak signal is achieved.
Use care so as not to damage the potentiometer.
3
Turn the Automatic Gain Control switch ON
Local Video Out
Provision is made for the connection of a local video monitor to assist in setting up the camera. Use
the optional service connector DM/ICED-SERV (not supplied).
Final Assy
When all the connections and adjustments have been made, re-attach the camera liner and dome
cover.
