A complete push-to-talk and team-safety platform — built to beat legacy PTT apps and the radios themselves.
Hold to talk and reach a whole channel or one person in under a second. Multiple talkers, no floor lock — PTT over any network.
Team, broadcast and dispatch channels. Announce to everyone at once — and reach people who are offline by text.
One tap sends a high-priority alert with GPS location and a live hot-mic to your emergency channel — far beyond what a radio can do.
Welfare check-ins, duress and man-down alerts with automatic escalation — protect solo and high-risk staff.
See your team on a live map, get geofence alerts, and run NFC/QR/GPS guard-tour checkpoints with proof of presence.
A dispatcher sees the queue of calls and alerts, responds and replays. Record channels to a vault with AI transcription & summaries.
Wherever teams once relied on two-way radios, Sentriplex does more — on the phones they already carry.
Guard-tour patrols, panic/duress alerts and lone-worker monitoring for security companies and in-house teams.
Store-floor coordination, loss-prevention call-outs and instant manager broadcasts.
Hands-free push-to-talk across large sites, docks and yards — with location.
Hotels, venues and event crews coordinate staff and respond to incidents fast.
Porters, facilities and care staff stay reachable with check-ins and SOS.
Crews on sprawling, low-coverage sites talk over cellular with man-down safety.
Sentriplex isn't a chat app with a mic button. It's a push-to-talk platform built for teams whose job is to keep people and places safe.
No proprietary radios, no licences, no coverage gaps — just the phones in their pockets, with unlimited range.
