Trouble Shooting
No Picture:
- Check the supply voltage to the camera.
- Check the BNC video lead connection. The centre core carries the video signal
and the outer core or screen is the ‘video signal return’
Picture too bright or dark:
- The ALC control is not set correctly
- The BLC switch needs setting
Poor Night Time Pictures:
- Check the dip switch confi guration, if the camera is supplied with an auto iris
lens as standard then this should be set for ALC (Auto Iris) and not ELC
(Electronic Iris).
- Check the dip switch confi guration that D/N has been selected.
- Check the setup of the camera in its brightest operating conditions and adjust
the DC level control as described in the instructions.
- Select DSS to allow the camera more exposure time.
- Check there is suffi cient lighting available for the area being viewed.
Poor Focus:
- Check the lens adjustments for focus.
- Check the DC level control. This controls the iris aperture and if it is open too
much then the picture will not be sharp.
- Check that the dome cover is clean.
To clean the cover, use a soft dry cloth. Do not use caustic or abrasive cleaners
that may scratch the surface.
