Push-to-talk for construction crews and the site office
The slab calls for the next mixer and the gate sends it. The cabin board reports a power cut before anyone walks down. A new subcontractor crew joins by QR on Monday and drops off when its contract ends.
- Cabin 2 power board: Cabin 2 board: power to floor 5 is off
- Concrete foreman: Floor five. The vibrators just stopped. Hold the next mixer at the gate.
- Gate: Gate. Holding mixer four, the driver knows.
- Concrete foreman: Cabin 2 board: the floor 5 breaker has tripped.
- Site office: Don't reset it yourselves. The electrician is on his way, five minutes.
- Concrete foreman: Power's back, the electrician swapped a cut cable. Send mixer four.
- Gate: Mixer four is on its way to the pump.
How PRIVOX helps
- CREW-5 · TALKING
The slab and the gate on one key
The crew on floor 5 presses a hardware key, gloves on. The gate holds or sends the next mixer at once.
- GATE-10:42 · FULL DUPLEX
A private word with the pump
The foreman calls the pump operator one to one, like a phone call. The crew keeps the channel for the pour.
- Cabin 2 power boardNo powerIndoor21.4 °CMainsOn
The board reports a power cut
A sensor on the cabin board alerts the concrete channel the moment power to the floor drops.
- SOSFROM CREW-5ALL GROUPS · CONSOLE
SOS to every crew
The SOS button reaches every crew and the site office at once, whatever channel the person is on.

How we adapt to you
Groups by crew and trade
Concrete, electrics, facade, deliveries: each crew has its own group. The site office hears them all and speaks into any.
Subcontractors for their contract
A new crew joins by QR card on Monday. Its group has an end date and closes itself, and the history stays.
Listen-only for the client's supervisor
The client's supervisor or a trainee follows a crew's channel without talking, so the air stays with the people working.
What we can add
A bridge to site DMR
We connect a DMR channel already used on site to a PRIVOX group, so handhelds and phones hear each other.
Live translation for mixed crews
The foreman speaks Latvian, and the crew hears Russian, Ukrainian or English. We add it on request.
Lone worker check-ins
Someone working alone at the weekend confirms at agreed times. A missed check-in notifies the site manager.
