- Dementia
- Wandering risk
- Door monitoring
This wireless door alarm chimes a portable receiver when a monitored door opens, giving caregivers early warning of dementia wandering. It is an alert aid, not a lock or a monitored service — it will not prevent someone from leaving and does nothing if no caregiver is present to respond. Test it regularly and keep sensor batteries fresh, since a dead battery means no alert. Use it as one layer alongside supervision, a GPS tracker, and a secured home.
Pros
- Alerts a caregiver the instant an exterior door is opened
- Peel-and-stick install — no tools, wiring, or WiFi needed
- Expandable to cover several doors and windows
- Inexpensive with no monthly fees
Cons
- Only alerts — it does not physically stop someone from leaving
- A caregiver must be present and able to hear the receiver
- Battery-powered sensors need periodic battery checks

Frequently Asked Questions
- Will this stop someone from leaving?
- No. It chimes a portable receiver when a monitored door opens — it is an alert, not a lock, and it does nothing if no caregiver is present and able to hear it. Use it as early warning alongside supervision, a secured home, and a GPS tracker if wandering is a real risk.
- What does installation involve?
- Peel-and-stick contact sensors with no wiring, no Wi-Fi, and no tools. Range is long enough to cover a house, volume is adjustable with several ringtones, and you can add sensors and receivers to cover multiple doors and windows.
- Are there monthly fees?
- No — it is a one-time purchase around $40 with no subscription. A Wi-Fi/app version is available if phone alerts matter more than an in-home chime.
- Do the sensor batteries need checking?
- Battery checks. The sensors are battery-powered, and a dead battery means no alert at the moment you most need one. Test the system regularly rather than assuming it is working.
