Summary

If you are having difficulty getting clear live views under low light conditions with your Vandal

Proof IP Dome or the Fixed IP Dome, this is likely due to IR reflections inside the camera. To

solve the IR reflection problem, you can choose to disable the IR Light function if there is

sufficient lighting on the installation site. If you do not have enough lighting on the installation

site, proceed to identify the possible causes and adopt the solutions to reduce IR reflection

and improve the quality of live view.

Disabling the IR

By default, the IR LEDs turn on when there are insufficient lights. To avoid IR reflection inside

the camera, you can disable the IR function if there are sufficient lights or an IR illuminator

installed on the installation site. The disabling the IR function is available on the camera with

firmware version 1.07 or later.

Note: The minimum amount of light (in lux) required in night mode and the corresponding

live image are detailed below.

For GV-VD120D/121D/122D/123D, GV-FD120D: approximate 4 lux.

For GV-FD220D/320D, GV-VD220D/221D/222D/223D,

GV-VD320D/321D/322D/323D: approximate 8 lux.

2. Is the rubber band around the lens loosened?

The rubber band around the lens prevents IR LED light from reflecting inside the camera

cover. If your rubber band is loosened or not properly fitted, some light may reflect inside the

cover and affect the quality of the live view.

GeoVisionInc. 9 RevisionDate:11/9/2011

Top view: The rubber band is at its normal position.

Side View: The rubber band is at its normal position.

Solution:

Check if the rubber band is properly fitted and completely attached to the camera cover when

the cover is attached. If your rubber band is still loose after your adjustment, contact the

vendor or local distributor for replacement.

3. Is my cover dirty?

regular maintenance.
