Multi-channel push-to-talk with sensors tailored to your business processes
Phones, rugged radios and a browser console talk on the same channels over LTE and Wi-Fi. Temperature, leak, door and power sensors raise alarms right there. We set up channels, roles and alarm rules around the way your company works.

Sensors that fit your processes
From a fridge to a pump room: every sensor gets its own limits, and its alarm goes straight to the people who act on it — on the channels your team already uses.

How an alarm turns into action
- Cold room above 8 °C for 10 minutesNight technician’s phone · console · production manager in Telegram
One press: “On my way”. A photo goes to the chat once it is fixed.
- Water on the pump room floorEngineer on call · facility manager
If one person is not enough, a group alert wakes the whole team.
- A door opens after 22:00Patrol group · duty desk
The nearest guard answers on the channel; the console shows who is closest.
- A sensor is silent for 30 minutesMaintenance group
The battery or the connection is checked before the gap in data matters.
We choose the sensors and connect the ones you already have: over Wi-Fi or LoRaWAN, or from your controllers via webhook, e-mail or MQTT. Limits, alarm routes and schedules we set up with your team, and an alarm can also reach a manager in Telegram.

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.
Questions
Do we have to buy radios?
No. Start with the phones your people already carry and add rugged PoC radios where a hardware key matters. Everyone talks on the same channels.
What happens without internet?
Phones, radios and the console need LTE or Wi-Fi. Sensors in places without Wi-Fi can connect over LoRaWAN through a gateway on site. Spots without coverage are mapped before the pilot starts.
Where do our conversations and data live?
On a PRIVOX server — in our cloud, or on your premises if conversations must stay inside your perimeter.
Which radios work with PRIVOX?
Android PoC radios with a hardware PTT key — such as the Inrico T320 — and any Android phone or iPhone. Using another model? Tell us which, and we will set up its keys.
Can contractors get temporary access?
Yes. Accounts and groups can carry an end date and lapse on their own. People join by scanning a personal QR card.
