Tello-Bridge

Bridge every device.
Radios, cameras, networks.

Tello-Bridge integrates your existing surveillance cameras, legacy DMR radios, and dispatch consoles — into one unified operations layer. No hardware swap. No retraining. Your fleet keeps the radios it already knows.

Capabilities

Six things the bridge does on day one.

DMR ↔ PoC voice bridge

Talk groups span both networks. A DMR handset and a smartphone PoC user are on the same channel, in real time.

GPS for every handset

Locate DMR units that never had GPS dashboards before. Stream positions into mission control.

Device telemetry

Battery, RSSI, last-seen, online/offline. Catch issues before crews report them.

Group sync

Add a unit to a talk-group and it propagates to both DMR repeaters and PoC server.

No retraining

Field teams keep using the radio they already know. The bridge is invisible to them.

No radio replacement

Keep your installed base. The bridge sits at the gateway — devices are untouched.

Tello Lite

Enterprise PTT that just works.

Tello Lite turns any phone into a PoC handset — and the bridge handles the rest. Your DMR teams keep their radios. Your office staff, contractors, and partners use a phone. Everyone hears each other on the same channel.

Sub-2-minute onboarding.Sign in with the mobile number your organization registered and confirm the one-time passcode (OTP) sent by SMS. Groups load automatically. First transmission in seconds.
Transparent bridging.Lite users don't know they're talking to a DMR radio. The system routes voice and presence across networks invisibly — same channel, same map.
Background PTT & native CallKit.iOS native PTT layer keeps the connection alive in the background. Calls come through even when the phone is locked.
Live roster + map.See every team member online, where they are, and their last transmission. DMR units appear on the same map.

DMR compatibility

Standards-based. Vendor-independent.

Tello-Bridge integrates seamlessly with standard DMR Tier II devices from leading manufacturers, surveillance cameras, and NVR/VMS systems. That means no firmware changes, no vendor lock-in, and no rip-and-replace — your fleet keeps working exactly as it does today.

Architecture

How a DMR transmission becomes a PoC alert.

01
DMR Radio→Gateway
Existing DMR fleet stays in place. Voice and data hit the Tello Gateway.
02
Gateway→Tello Cloud
Gateway translates DMR frames into Tello's mesh protocol over secure tunnel.
03
Tello Cloud→PoC App
PoC users see DMR units on the same map and hear them on the same channel.
04
PoC App→Mission Control
Operators in the dashboard see one unified fleet, regardless of underlying network.

Deployed for

Where bridging matters.

Airports

Bridge ramp DMR fleets with terminal staff on smartphones. One channel for everything moving on the apron.

Public safety

Connect agencies running incompatible radios — temporary or permanent — without forcing a migration.

Oil & gas

Site teams keep their hardened DMR; head-office and contractors join from PoC apps.

Logistics hubs

Yard radios + driver phones on the same dispatch channel.
