With the Door eGuard DG 8200, you can store images of visitors even when you are not at home. This electronic peephole features a doorbell function that automatically takes a photo of the visitor when the doorbell is pressed. This way, you can see who rang your doorbell during your absence. Thanks to a 0.3 MP camera, a 4-inch TFT screen, and a resolution of 480 x 320 pixels, people at your door are clearly visible. The infrared LED light allows the peephole to provide a clear, sharp image even at night. The peephole can be easily installed in standard doors with a thickness of 38 to 110 mm. Installation should only take place indoors. The diameter for the hole should be at least 14 mm and a maximum of 22 mm (DG 8100) or 26 mm (DG 8200). Both models are battery-operated, making them wireless and not dependent on a power outlet. This electronic peephole takes less than a second to become operational.
