The Sentry is a wireless magnetic sensor with a 3M double-sided adhesive mount on your window or door. The device has a tamper switch that prevents accidental removal, and the battery is replaceable. Sentry is ideal for wirelessly monitoring climate-sensitive environments where refrigeration doors could be left ajar, causing significant inventory loss. It offers 24 hours a day monitoring, real-time alerts, logs, and reports.
