Unauthorized access detection
Unauthorized access detection is the ability to identify and alert when a person or vehicle enters a restricted, controlled or off-limits area. It differs from motion detection because it works on defined zones with rules about who should be present and when, and it differs from access control because it watches what happens after the door opens. Camzify runs it on the cameras already covering those doors, rooms and corridors.
- A notification window per camera
- Tailgating counted at controlled doors
- Restricted rooms checked on the round
The badge reader stops at the door
An access control system records that a badge opened a door at 22:14. It does not know that two people walked through, that the door was wedged open for the next hour, or that the badge belonged to someone who left the company in March. The camera above the door recorded all of that, and nobody was watching it.
The gaps are not exotic: tailgating, propped doors, shared badges, and the contractor who was let in for one job and kept the access. Conventional CCTV catches every one of them on video, after the fact, if someone knows which hour to scrub through.

Rules on the space, not on the door
Zone intrusion detection draws the restricted area on the camera view, the server room floor, the cash office, the roof, and the camera carries the notification window during which nobody, or nobody unaccompanied, should be there. A tracked person inside the zone during the window raises an alert with the snapshot. Tailgating detection watches the controlled entrance itself and fires when more than one person passes on a single badge event.
On top of the detections, a patrol round checks the restricted rooms on a schedule: door closed, room empty, nothing left propped. It records the answer with a snapshot whether or not a detection fired, which is the evidence that the control was working, not just that it existed. Where the concern inside the door is a person rather than a place, violence and weapons detection runs on the same cameras.

What a restricted-areas round checks
The round for this use case is the cameras covering the rooms and corridors that access control is supposed to protect, and the checklist is the state each should be in: door closed, room empty, nothing propped, nobody on the floor after hours. A passing round is the evidence that the restriction held at each time it was checked.
Where the round is automated, the AI can watch a scene for a few seconds before judging, which is the difference between a person walking through a corridor and a person waiting in it.
A check found Not Compliant captures a snapshot and messages the guard designated for that camera; on a manual round the operator chooses to send it, on an automated round it goes on its own. The item stays Pending until it is marked Fixed, which captures the after frame, and the report shows both.
What it will not do
It will not check a badge or open a door; it is not an access control system and does not replace one. It will not identify people. It will not see into a room without a camera in it. And it will not decide what to do about the person in the server room at midnight; it puts the snapshot in front of the guard designated for that camera.
