Always know who's at the door with the Feit Electric Cam/Door/WiFi/BAT smart doorbell camera. This doorbell camera will alert your phone and send a live video when motion is detected outside your door. Use the Feit Electric app to tune in any time for a live look, or choose to receive an alert any time movement is detected. Converse in real time with a built-in microphone and speaker. Recorded events can be stored on-board in a separately sold SD card. Each camera is powered by a detachable battery pack, giving you peace of mind even if the power goes out.
