Restricted Zone Intrusion: who's where they shouldn't be
Restricted Zone Intrusion is a Svid check that raises an alert when a person shows up somewhere they shouldn't be, on the cameras you already have, with rules by camera and by schedule. A person in the plant room is always worth an email; a person in the loading bay only matters after seven, and the check knows the difference.
What it does
A zone is a camera plus a rule: nobody here, ever, for the roof access; nobody here between 19:00 and 06:00 for the yard; nobody without hi-vis belongs to PPE Compliance next door. When a person appears against the rule, it flags.
By camera and by schedule
Rules follow the working day, so the same camera can be open at 2pm and restricted at 2am. There are no geofences to draw and no beams to align. If the camera can see the space, the space can have a rule.
The places this gets pointed at
- Plant rooms and electrical intake rooms
- Roof access and ladders
- Chemical and high-value stores
- Back-of-house corridors in mixed-use buildings
- The whole site outside working hours
That last one is where this check quietly becomes the intruder alarm that comes with footage attached.
What the alert looks like
An email reading something like "a person has entered the plant room, camera 9, 02:14", with a description of what's visible, outfit and build, and a link to the exact moment; a JSON webhook for control rooms and anyone on call. The description matters: it's how the on-call engineer tells the night cleaner from a stranger before leaving bed.
Where it runs and what it costs
Enabled per camera by definition. It runs on RTSP feeds, uploaded files, or a live phone camera for a temporary exclusion zone around works. Cloud is the default, with a fully on-prem appliance mode for sites that keep footage on premises. The Store shows this check with a live monthly figure computed from your own cameras and usage, as "+$X/mo at your usage", and the subscription underneath is based on your own usage with a $9 a month floor, arithmetic shown at signup. See the pricing section for how it's worked out.
- Can I set different rules for different times of day?
- Yes. Rules are per camera and per schedule, so the loading bay can be open at noon and restricted at midnight.
- How is this different from a door alarm or beam sensor?
- A sensor knows something crossed a line. This sees a person, describes them, and hands you the footage of the moment, and it needs no wiring beyond the camera that's already there.
- Does it recognise who is allowed in?
- No, deliberately. There's no facial recognition or biometric IDs, so it flags any person in the zone, and the description plus the clip lets a human decide in seconds whether that's the boiler engineer or a problem.
