Video doorbell detection ranges vary by model, movement and settings

Video doorbells do not alert whenever someone appears in view: detection depends on the sensor, movement, settings and surroundings as well as distance. Ring gives a standard maximum range of about 30 feet, but that is not guaranteed, and larger objects such as cars may trigger alerts from farther away.

Published ranges vary by brand and model: eufy says its doorbell reliably detects horizontal movement up to 15 feet and vertical movement up to five feet; Arlo lists 13 or 16 feet for different models, while TELUS says its sensor works best within eight feet and needs at least seven seconds of continuous movement. Passive infrared sensors respond better to side-to-side movement, while video analysis compares frames. Adjusting sensitivity, motion zones or camera angle can help reduce missed or unwanted alerts; Ring recommends mounting its doorbells 48 inches above the ground.
