For simplicity I will call a device that uses the double split experiment to detect if someone has percieved the device a "quantum perception switch" or QPS.What exactly do you suppose this QPS does? If it watches the door of the room, then it detects the person directly, and the double slit setup seems to not even be required. So it is watching only the double-slit setup. Exactly what would distinguish the experiment running with or without an observer? You can win a Nobel prize if you can answer that.

If I put a QPS attached to the ceiling in the middle of a secure room would it send security a message any time somebody enters the secure room?Only a Schrodinger's box is secure. I'm willing to posit one, even though the best one ever built barely managed to contain an object just large enough to see without instruments.

Would a cat activate the QPS?Depends on what it is set up to detect. You haven't told anyone this.
Would a camera actiate the QPS?
