    Abstract: An electronic door peephole system for a peephole of a door includes a viewing unit and a monitoring module. The viewing unit includes an image capturer adapted for installing into the peephole of the door to capture an image at an exterior area to the door and a wireless controller operatively linked to the image capturer for wirelessly transmitting the image captured by the image capturer. The monitoring module is wirelessly linked to the wireless controller for processing the image transmitted therefrom so as to visually display the image away from the door. Therefore, a viewer is able to watch the visitor or the event outside the house away from the door for safety purpose.
