Features
A physical cover that can be closed to block the camera lens. When not using the webcam, you can physically prevent unwanted recording and protect your privacy. Provides peace of mind against hacking or accidental activation.
This document camera does not have a privacy shutter. Users concerned about privacy may need to consider alternative methods to cover the lens when not in use, such as using tape or a separate lens cover.
Automatically adjusts brightness and contrast to provide a clear image even in dimly lit environments. Useful for video calls in rooms with poor lighting or at night. Allows clear facial expression even in dark settings.
The product description mentions adjustable image brightness with 3 levels, which suggests some form of automatic light correction. This feature helps to improve image quality in varying lighting conditions, ensuring a clear picture even in dimly lit environments.

The product information does not mention a tripod mounting function. Users who require stable placement and flexible angle adjustment may need to find alternative mounting solutions or consider other document cameras with this feature.
