3. Camera Controller

To control the Photo Webcam, we recommend using Raspberry Pi 3 Model B. Raspberry PI is particularly ideal to control cameras. Avisec offers two different solutions:

Covering LEDs

To avoid light reflections from the LEDs, you can cover them with a dark lacquer. Commercially available nail polish without additives is suitable.
