PRIVOX or Zello on your push-to-talk radios
Both run on the same Android PoC radios and phones. PRIVOX adds sensor alarms in the same channels, a group alert that rings every phone and a browser console for the dispatcher — set up by our team around your processes.
What stays the same
If your team already talks on Zello, the everyday work does not change:
- Push-to-talk over LTE and Wi-Fi, between sites and cities
- Android and iPhone apps, rugged PoC radios with a hardware PTT key
- Text, photos and voice messages next to the channel
- A live map for the dispatcher, switched off for anyone who should not share location
- Sign-in with a QR code, encrypted traffic

Sensors in the same channels
A fridge, a pump room or a gate raises its alarm on the radios of the people who act on it.

A group alert that rings
At night every phone in the group rings like a call. The first to answer is already on air.

Already on Zello? Keep your radios
PRIVOX installs on the same Android radios and phones. You move one site at a time.
- 01
Tell us the model
We set up its PTT, SOS and channel keys for PRIVOX.
- 02
One site first
PRIVOX goes onto the radios and phones of one site. The other sites keep working as before.
- 03
Channels and sensors
We recreate your channels and roles and connect the sensors that site needs.
- 04
Decide on real shifts
After the pilot you see how fast alarms reach people and choose for the other sites.

Questions
Can we keep our radios?
Yes. PRIVOX runs on Android PoC radios with a hardware PTT key — the same kind of radio Zello runs on. Tell us the model and we set up its keys.
Can Zello and PRIVOX work at the same time?
Yes. During the pilot one site works on PRIVOX while the other sites stay on Zello.
Where are our conversations and data?
On a PRIVOX server — in our cloud or on your premises. With your own server, voice, messages and locations stay inside your perimeter.
Which sensors can we connect?
Temperature, humidity, water leak and level, doors, motion and power — over Wi-Fi or LoRaWAN — plus alarms from controllers you already have via webhook, e-mail or MQTT.
Start with one real site
We set PRIVOX up on one of your sites — with your people, your channels and your sensors — and agree up front what a good result looks like.
- A 20-minute call
We go through your sites, shifts and the alarms that matter most.
- A live demo on your devices
Phones, radios and the console — on your site or remotely.
- A pilot on one site
Your shift works on PRIVOX. Together we measure how fast alarms reach people and get an answer.
