PRO · BLIND-SPOT CHECK
See what no camera sees. Then close it.
Point Sentinel at your own estate. It maps the ground no running camera covers, ranks every gap by what matters, shows where the next cameras would close the most — and gives you a signed report to prove the coverage you have.
An audit of a demo estate: the gaps, the cameras to fix, and a signed report one click away.
What the audit shows
Coverage you can measure, not assume.
Most estates are planned once and drift: cameras moved, cameras off, cameras pointed at a wall. The audit shows where the picture really stands today.
What no camera sees
Each camera’s field of view is drawn from its position, direction, angle and range; Sentinel unions them and maps the ground left over, within the area you choose to audit.
Cameras that are not pulling their weight
Cameras that are not running, cameras with no direction set, and running cameras that add almost nothing — each listed with what to fix.
Gaps ranked by what matters
Coverage-only ranks gaps by size. Coverage + observed traffic (Pro) weights them by how your estate is actually used — from movement across the whole network, never one person’s history.
Where the next cameras go
Ask for the next N cameras and Sentinel proposes positions and aims, each with the blind ground it closes — the biggest gain first, so a budget goes where it buys most.
A signed Coverage Assurance Report
Export the audit as a PDF carrying a SHA-256 hash and your organisation’s signature. Every export is recorded, and the run keeps its inputs, so the report can be reproduced.
A lower bound, said plainly
Coverage is modelled as a flat ground sector per camera; walls, vehicles and terrain are not. So the blind area shown is equal to or smaller than the real one — never larger — and the page says so.
How it works
From camera positions to a signed report.
Choose the area
Pick the part of the estate to audit — a site, a district, a perimeter.
Run the audit
Coverage only, or coverage weighted by observed traffic. The run freezes its inputs so it can be repeated.
Read the gaps
Blind share, blind area, gap count and covered ground, then every gap ranked with its nearest camera.
Harden and report
See where the next cameras close the most, then export the signed report for your auditor or board.
