Overview
A renter or homeowner can stick one on each entry point and get a loud alarm when it opens. Each contact sensor runs on alkaline cells and lists door mounting, touch controls and a chime mode.
The reason to buy is simple, loud protection for several doors and windows without wiring or a subscription. The limit is that the listing names no hub, phone alert or camera, and the mounting hardware and batteries are not described. Each alarm only sounds locally.
Who it's for
Apartments, garages and extra bedrooms where a noisy deterrent is enough fit well. It does not suit people who want to see activity from away or who need to link sensors to a hub.
Pros and cons
- Six alarms in one pack
- Loud local alarm
- No wiring needed
- Chime mode for visitors
- No phone alerts listed
- Batteries not stated as included
- Mounting hardware not listed
Performance notes
The contact sensor triggers when the door or window moves away from the matching half, and the siren sounds at the listed level. Because there is no hub, the alarm only warns people nearby. Placement near the frame edge gives the most reliable trigger.
