A unique and and secure communication solution
The APPI-Com is the most compact solution in its class, roughly the size of a credit card, and activates your network at the press of a button. Thanks to our patented SyncAll® technology, even if a radio drops out of the network—whether due to signal loss or being powered off—the rest of the team stays connected without disruption. Once reconnected, the device seamlessly joins the conversation with no manual intervention required. For added safety, the APPI-Com includes built-in lone worker protection, including :
Immobility detection: APPI-Com is embedded with a sensitive electronic motion sensor: once immobility is detected, the APPI-Com produces an audible warning and a voice message to the entire group.
Network connection failure: the APPI-Com's Safeline® technology sends a notification the team in case of a disconnection in the group.
User-activated alerts: With the press of a button, users can activate the embedded pager to call attention to their team.

APPI-Com radios transmit on a proprietary, digitally encoded, auto-deployed radio network operating in the license free bands around the world. The maximum radio emitted power level is capped at 500mW which is 4 times less than a smartphone.
Moreover the system prevents not only any form of intrusion from any other voice-com radio but also from another unknown APPI-Com LR.
