What to know before buying

Listing details to confirm

The listing describes motion-triggered app alerts, while its technical details label the alert type “Motion Only”. The claimed motion-sensor coverage is also inconsistent: one listing detail gives a maximum range of 9 Metres, while the feature text claims 100° coverage at up to 30 feet. Battery-life figures are manufacturer claims and may vary with use. Check the selected listing for the exact sensor range and alert behaviour.

Customer feedback describes setup as easy and reports positive impressions of the sensors, motion detection and value. It also includes reports of some units failing within two weeks, alongside concerns about siren quality, low audibility and connectivity or integration. Those sound concerns matter if the alarm is expected to alert people outside, while connectivity concerns are relevant to buyers relying on remote app alerts. The aggregate rating is generally positive but does not resolve these specific trade-offs.
