Evidentia Cam: GPS Timestamp

Capture proof, not just photos.

Evidentia Cam turns your phone into a professional evidence camera. Every shot is permanently stamped with verified time, precise GPS coordinates, a British National Grid or Irish Grid reference, altitude and a real-world address — burned directly into the image at the moment of capture. When you need to prove exactly where you were and exactly when, this is the camera that does it.

Built for the people whose photos have to stand up to scrutiny: surveyors, insurance assessors, building inspectors, utilities crews, highways teams, site managers, tradespeople and anyone documenting work in the field.

WHY EVIDENTIA CAM

Verified time, not just the phone clock
Evidentia Cam synchronises with internet time servers and flags whether the timestamp is independently verified — so your photos carry a trustworthy time, and you know when they don't.

Pinpoint location, every format you need
Latitude and longitude, British National Grid reference, Irish Grid reference for Northern Ireland and the Republic, altitude above sea level, and a readable address — all stamped on the photo.

Works where you work — fully offline
No signal at the bottom of a field or inside a structure? No problem. Coordinates, grid references and offline address lookup all work with zero internet connection, powered by built-in mapping databases covering Great Britain and Ireland.

Real addresses from real data
An onboard location engine identifies the nearest named landmark — church, school, farm, industrial estate, pumping station and more — or falls back to the street and area. Built on Ordnance Survey and OpenStreetMap data.

A live map on every photo
An optional minimap overlay shows your exact position and heading, embedded straight into the image.

PRIVATE BY DESIGN

Your photos are yours. Evidentia Cam stores images on your own device and never uploads them to us — we don't collect your photos, your location or any personal data. No account required. No advertisements.

ACCURACY YOU CAN RELY ON

Coordinate conversions use recognised Ordnance Survey transformations, with sea-level altitude correction and grid references suitable for professional record-keeping. Location accuracy depends on your device's GPS hardware and conditions at the time of capture.
