Do not block the camera's field of view . Make sure that no walls, tables, or objects are
too close to the camera . If an object is within 2 .5 inches of the sides or front of your
camera, it can reflect light back into the camera lens and cause glare or hazy video .
The Smart Cam has advanced motion detection capabilities and night vision that
are powerful enough to allow the camera to detect events and faces, even at night .
For optimal facial recognition results, place the camera at eye level .
