CAM-336

Someone has been standing at the fence for four minutes

Mid-afternoon at a valve station on the coast. A gray car is stopped outside, on the dirt track, where nobody stops. A few feet away a person stands against the mesh, hands on the wire, holding a tool. On the other side of the gate a worker in a safety vest walks along the road. IRIS sees somebody staying put at the fence and a vehicle stopped outside, and it times both.

What this camera measures

An alert says something’s happening. The reading says how much.

17:24time the person stopped
04:12time spent standing at the fence
1people stopped outside
1vehicles stopped outside
3times the same car has driven past today

The figures on this screen are an example from the illustration, not any client’s measurement.

The rule

You decide once. IRIS applies it always.

a person or a vehicle stays beside the fence for longer than the time the site sets

Then

alert the security center with the camera, the time and the image
save the video from the moment the clock started running
count how many people and vehicles are stopped outside

The instruction that set it up«Tell me if somebody stays at the fence for more than two minutes, or if a vehicle stops on the perimeter track.»

What changes

What changes for whoever answers for the plant

Mid-afternoon, and there’s nobody at that remote station: the nearest crew is forty minutes away by road. On that track it’s normal for a car to drive past; what isn’t normal is for it to stop and for someone to stand still against the fence. That difference — passing or staying — is the one that counts. IRIS times how long the person stays and alerts the control center with the image, so the operator can call or send someone while it’s happening, and not when a hole shows up the next morning.

What people usually ask

Does IRIS identify the person at the fence?

No. IRIS does not recognize faces and does not compare them against any database. It detects a situation: somebody staying beside the fence for longer than the site allows. It alerts with the camera, the time and the video. Who that person is, and what happens next, is decided by people and, where it applies, by the authorities.

Won’t it go off every time somebody walks past?

No, because it doesn’t trigger on passing by: it triggers on staying. The rule is written with a time — two minutes, five — and with the exact area of the frame. Somebody walking through sets off nothing. A car that stops on a track where nobody stops does. That threshold is set by the site, not by the camera.

Does it work at night or in fog?

It depends on the camera, not on IRIS. With a camera that sees at night — infrared or thermal — the detection keeps working. If the optics can’t see, neither can IRIS. That’s why perimeters combine views: one covering the track and one tight on the fence, and whichever works at that hour is the one that counts.
