Hikvision iDS-2CD7146G0-IZ(H)S(Y) — 4 MP DeepinView Analytics Dome

Call this a security camera and you undersell it by about half. It is closer to a measuring instrument that happens to record video.

It counts people and deduplicates them, so somebody who walks past the till three times is one visitor, not three, and it files that into daily, weekly, monthly and annual reports. It watches up to eight regions for queues and reports not just how many are waiting but how long they have been waiting. It builds heat maps in space and in time, so you can see both where people stand and when. It checks whether hard hats are on across up to thirty people at once. And it can tell you whether the station that should be staffed is staffed.

The security functions are all present too — human, face and vehicle detected simultaneously, perimeter rules, face comparison against libraries totalling 150,000 — but if all you need is a camera that spots an intruder, you are paying for a great deal of arithmetic you will never run.
