Proof of patrol
How do you prove a security guard did their patrol?
Updated 23 June 2026
Security companies document a patrol with GPS check-in and check-out per visit, a completed round checklist, timestamped photos, and incident notes, then share a client report. In provvio, GPS verifies the visit against the site geofence, not each point on the round; checklist entries record what the guard marked complete.
Security work has the same invisibility problem as overnight cleaning: the patrol happens when nobody is watching, and a paper sign-in sheet proves almost nothing because it can be filled in from the car park. When a client asks why an incident was missed, 'the guard says he walked it' is not a defensible answer. Documenting patrols means recording arrival and departure against the site geofence, then adding a round checklist, photos, and incident notes. provvio does not track guards continuously or GPS-verify each point on the round.
Four ways to prove a security patrol happened
GPS-verified check-ins and a round checklist
The guard checks in on arrival and the app records the location and time against the site geofence, then ticks each point on the round as it is checked. A geo-stamped visit with a timed checklist is far harder to fake than a signature on a clipboard.
Timestamped patrol photos
A photo of the locked gate, the clear loading dock, the alarm panel. Timestamped images show the guard was physically present and the area was checked, not just logged.
Incident and exception logs
When something is wrong, the guard logs it with a photo and a note on the spot. The client gets a defensible record of what was found and when, instead of a phone call hours later.
Automatic client report
At the end of the shift a branded report with check-in times, the round checklist, photos, and any incidents lands in the client's inbox. The proof of the patrol arrives before any question about it does.
Frequently asked
What is the best proof that a security guard completed a patrol?
Use several records together: GPS check-in and check-out for the visit, a completed round checklist, timestamped photos, and incident notes. In provvio, GPS records arrival and departure against the site geofence; it does not verify every point along the patrol route.
Can guard patrol check-ins be faked?
A good proof-of-service app compares the device's GPS against the site geofence and flags check-ins outside range, so a guard cannot log a visit from the car park down the road. provvio flags out-of-range check-ins rather than silently accepting them.
Is this better than a guard tour wand or NFC system?
Phone-based GPS check-ins remove the cost and breakage of dedicated wand hardware, add photos and incident notes in the same flow, and send the client a report automatically. For most patrol contracts that combination is both cheaper and more transparent.
Do clients actually review patrol reports?
The value is less that every client reads every report and more that the record exists. When an incident or dispute happens, you send the timestamped proof pack instead of arguing from memory, and the conversation ends quickly.
