If you nd your image is out of focus, use the AUTO FOCUS function to let the camera nd
the optimal image focus.
You cann use the << or >> buttons to ne-tune the imaging results. Normally the AUTO
FOCUS function can deliver the best results.
The Day and Night setting is also available on this page. You can change the IR cut lter
and the light sensor sensitivity settings. Normally the default setting sufces ordinary uses.
The IR cut lter is turned on or off depending on the lighting level detected by the onboard
light sensor.
