Not all video doorbells detect motion equally. Ring devices typically have a maximum motion detection range of about 30 feet (9 meters), though larger objects like cars can trigger alerts from farther away. However, maximum distances aren't guaranteed and can fall short depending on sensitivity, mounting, and surroundings.
eufy's Video Doorbell reliably detects horizontal motion up to 15 feet and vertical motion up to 5 feet. Arlo lists a maximum of 13 feet for its second-generation model, with Essential wired and wire-free models at 16 feet. TELUS recommends a range within 8 feet, noting its sensor requires continuous movement for seven seconds or more to trigger a clip.
Detection depends on more than distance. Passive infrared (PIR) sensors are more sensitive to side-to-side movement, while Pixel Difference Analysis (PDA) compares video frames. Some cameras, like Simpli Safe, combine both. Adjusting Motion Sensitivity and setting custom motion zones can improve detection.
Mounting matters—Ring recommends installing doorbells 48 inches off the ground. Busy areas may drain battery-powered devices faster. Free alerts are standard, but viewing recorded video often requires a subscription.
