Software for the people who work on site.
Sentrio Systems builds practical, mobile-first tools for companies whose staff work on site, on shift and often without signal. We start with security guarding, the industry we know, and we build for the phones guards actually carry.
Products
One product today, built end to end with a guarding company as the first customer. More frontline tools will live under the same roof.
Truepost
The app security guards book on with and the office controllers run the day from: photo and GPS book-on, hourly site reports, a tamper-evident occurrence book, incidents, rosters, timesheets and PSIRA compliance packs.
Next
The same engine, rostering, proof-of-presence and reporting, fits cleaning, facilities, farm security and driver teams. If that is your business, we would like to talk before we build it.
How we build
Four rules we do not break, because our users are standing at a gate at 02:00 with a R900 phone and one bar of signal.
Offline first
Every action works without a network and syncs later. Bad coverage is normal, not an edge case.
The cheapest phones
If it does not run well on an Android Go handset, it is not finished.
Plain language
Screens a low-literacy reader can use, and privacy notices a guard actually understands.
POPIA by design
Data in South Africa, isolated per company, tamper-evident records, and the person on the phone always knows what is recorded.
