An audio/video (A/V) recording and communication doorbell comprises a camera, a front button, and a motion sensor. The camera and the motion sensor are configured to work in tandem to detect motion in a field of view of the A/V recording and communication doorbell, such that a first one of the camera and the motion sensor detects motion and the other one of the camera and the motion sensor independently verifies the motion detection before an alert is sent to a user's client device. In this manner, user alerts from false alarm motion detections are reduced.
