Short range device benefits for lone worker protection
Locating indoors
Locating persons in distress indoors is easy to realize with custom on-site beacons connected to compatible lone worker alarm devices.
Attendance registration
Tags and door sensors are easy and fast to add to door openings for registration of persons carrying a SRD compatible personal alarm device.

Discreet to carry with
Smaller than any personal alarm device, a wearable button is light and discreet to carry and helpful to remotely control a paired and nearby situated personal alarm device.
Easy to take in use
All you need is a SRD compatible TWIG personal alarm device. TWIG short range devices communicate with a SRD transceiver in the personal alarm device, over a two-way 869 MHz ISM –band RF link.
