• Unlike the optical zoom, the graphics quality of the
digital zoom decreases as its zoom ratio increases.
• The auto-focus function may not operate normally
under the following conditions :
- When background illumination is low
- While Slow-Shutter is in operation
- If the zoom level is set too high
- When background illumination is too high
- If a long distance object and a close distance
object appear together within a monitoring area
- If there is no contrast, e.g. Ceiling or a wall
- If the camera is facing a thin horizontal line
• Auto Focus focuses on an object in the center of
the screen; objects around the screen edges may
not be properly in focus.
