DIGITAL DOOR PERIOD: The electronic door viewer has a built-in 0.3 MP camera. The image is displayed on the 3.2-inch diagonal screen after just one second, so you can see exactly who is at your door on the color display. Observation from the outside is not possible HIGH SECURITY: With the large viewing angle of 105°, you can keep an eye on everything that is happening in front of your door - even hidden people near the door are detected. The image is sharp and clear even in low light. However, the digital spy does not have an infrared LED, so night vision is not possible EASY INSTALLATION: The battery-operated door spy can be easily installed without drilling or tools, because the existing optical door spy only needs to be replaced and the Door eGuard can be inserted into the existing hole (14-22 m diameter). It is suitable for door thicknesses of 38-110 mm and should only be installed indoors SCOPE OF DELIVERY & DIMENSIONS: 1 BURG-WÄCHTER digital door spy Door eGuard GD 8100, incl. fastening material, 2 Micro AAA batteries, screen size: 3.2'' TFT, weight: 139 g, dimensions (HxWxD): 68 x 125 x 15 mm, Color white QUALITY SINCE 1920: BURG-WÄCHTER is a traditional family company with a special sense of responsibility for employees and the environment.
