ABUS Electronic Door Viewer The video spy hole makes it easy for you & your family to recognize strangers at your door – thanks to HD resolution (720p) & the display with zoom function. You’ll never again have to “glue” your eye to the peephole while holding your other eye shut in order to see something. The digital spy hole offers a real alternative, since you can view the display with both eyes at a convenient distance. The monitor is activated with the push of a button, allowing you to see who is at your door: with both eyes & at a convenient distance from the door. The recording takes place automatically (three individual images) – in case you later want to know who it was. The digital spy hole offers additional security for children & seniors in particular: that’s because the image on the monitor is easy to make out even if you are not very tall & have to look at it from below! Features 2.4" color display with zoom effect HD 720p resolution: 1280 x 720 (individual images) Electronic spy hole for convenient front door surveillance Save three images to the micro SD card upon activation to secure evidence Easy retrofitting within minutes Wireless installation, since it runs on batteries
