SiMPL Technology LLC 5-Piece Wireless Monitoring System

The 5-Piece Wireless Monitoring System gives you the convenience of a plug-in alarm plus the flexibility of a wearable alarm. The entry sensor, motion detector and solar-powered doorbell install anywhere with adhesive tape. When motion is detected, it sends an alert to the included plug-in alarm and wearable pager (up to 250 ft. away). No Internet, Wi-Fi, Bluetooth or subscription services are required.
