A stolen buoy could lead to a stolen life!

Sentry provides real-time monitoring of the presence of lifebuoys and water rescue devices within their housing. An award winning device that can be easily installed to new and existing installations.

Sentry uses a Self-Calibrating Sensor Unit, offering a reliable method to detect the removal of Life-saving equipment from an enclosure. Data is transferred over wide-area wireless comms systems using either cellular (GSM) or LPWAN technologies. Data is securely exchanged to a server computer, where the lifebuoy status can be viewed on a PC, laptop or mobile device.
