Motion in the frame is the wrong question
A camera on your gate also sees the road, the footpath and the neighbour's driveway. Anything working on motion across the whole picture reports all of it, so the most useful camera on site becomes the one everyone ignores.
What you want to know is narrower. Did anyone cross the gate line after hours. Did anyone go into the chemical store. Did the roller door open at 1am. A camera can answer those, once it knows where the boundary is.
How it works
- You draw the geometry on the camera view. A line across a gate, a dock approach or an aisle entrance. A zone around a restricted area such as a stock cage, a plant room or a fuel bowser.
- Detections are tested against it. The system already works out what is in each analysed frame and where it sits in the picture. A crossing is recorded when a person or vehicle moves from one side of your line to the other, and a zone event when one is inside the shape you drew.
- Direction can matter. On a dock or gate, going in and coming out are different events, so you can care about one only.
- Door activity is recorded the same way. A zone over a roller door or an entry records when it is being used, so you get activity by hour rather than a vague sense that people are in and out all day.
- Crossings become events, and events can trigger alerts. Each one is written to the event timeline with a clip around it. Where it falls outside your trading hours, the rules behind after-hours alerts email the people you nominate.
Footage stays on your recorder and analysis runs on our own server, not a third-party cloud. AI analytics covers the wider platform.
What you see and get
Your lines and zones drawn over the live view, a timeline of crossings and door activity per camera with clips attached, and alert emails when a crossing should not have happened. Over a few weeks the pattern becomes useful: which gate is used, when the dock really stops, how often a restricted area is entered.
Where it fits best
Yard gates and driveways, loading docks and roller doors, aisles into high-value or dangerous stock, plant rooms, construction compounds and retail back doors. See warehouses and logistics for how docks, aisles and gates are set up together.
What it does not do
- A line is drawn in the picture, not across the ground. It works in two dimensions, so a line that looks right on screen can read oddly for things far away or close to the lens.
- It does not control anything. No door locks, no gate opens. This is not access control and not an alarm system.
- Door activity is read from the camera view, not wired into door hardware, so it reflects what is visible rather than a signal from a reader.
- Crossings can be missed. Somebody hidden behind a truck, a person walking the line's edge, poor light or a camera knocked out of position all cost you events.
- It does not know who crossed or why. People still make the decisions.
