What to know before buying

The 500-foot figure refers to the sensor-to-receiver wireless operating range, not the sensor's 15-foot motion-detection range. The listing also gives a 360 degree rotation and 180 degree vertical tilt for adjustment, alongside a 30 degree vertical and 60 degree horizontal detection angle, so confirm the intended angle specification before buying.

Customer feedback highlights ease of setup, perceived functionality and a choice of ring tones. Sound level is mixed: some customers say it can be heard around the house, while others find it insufficient, and some report unexpected ringing. These concerns matter for a locally alerted system, especially if the receiver is placed far from the listening area. The listing's selectable volume and chimes offer adjustment, but do not guarantee that every placement will be audible or avoid unwanted alerts.

Negative themes

Mixed feedback

Sound level receives mixed feedback, with some finding it audible around the house and others saying it is not loud enough.
