Ir Zone Adjustment - Vivotek FE9191 User Manual

IR zone adjustment

The IR zone adjustment divides image planes to multiple sections, each single section is
equipped with an independent IR control lighting devices for local region illumination. This keeps
the comprehensive details of an approaching subject and preserves visibility for the background.
For an installation site with an unavoidable limitation, say, a wall that causes IR reflection, you
can manually reduce the light level on specific area(s). This can apply when an IR fisheye
camera is installed on a wall with a part of its field of view covering a wall.
Zone 5
IR adjustment
Auto IR adjust - This lets camera firmware automatically calculate and adjust light levels and come up
with the best balance for all illumination zones.
Manual IR adjust -
- One time adjust: Before you manually tune the IR light levels for different zones, press this button for
the camera to begin the initial calculation. After you manually adjust the light levels for zones, the
lighting levels will no longer be adjusted by the camera unless an object approaches near the
camera.
Observe the imaging results on the live view and pull the adjustment tabs to increase or decrease the
light levels in different zones. For example, when some unavoidable objects stand in one area, and you
observe signs of overexposure, you can lower the lighting level for it.
