Detection on cameras help

[jmwhooper]

I've got an outdoor camera and I want to detect if someone comes through the gate onto my driveway. I've tried various methods including crossing boundary, entering a region, through a door etc but it's not picking up the tests I've been doing.

I've attached an image showing a crossing boundary rule.

Any tips on best use of a region to detect the entry through the large gate?

Thanks

Try raising the line higher. Also try tipping the line at an angle (in your situation, low on the left, high on the right). I believe the "Crossing a Line" detection requires the center of the detected moving person/object to cross the line. With the line low, only a very short detection box would have the center cross the line. A tall detection rectangle would have to come deep into the driveway before the center would cross a low line.

It can take some mind bending to think in terms of a flat scene... the software does not know about depth in the scene. You have to take that into account when selecting the detection method.

"Entering or Exiting a door" also requires an opaque door, so the moving person/object will just appear in the scene, rather than come in from the side. If the movement is seen through the door/gate, it cannot just "suddenly appear".
