Eli5: how do traffic ticketers know that your car has been in a spot on the street longer than the time limit?

Question

I park on the street in my city and there’s a 2 hour limit for cars without residential permits. How do they know you’ve been parked for longer than the 2 hr limit? Surely they don’t have surveillance on every street and don’t take note of every car’s whereabouts every 2 hours. Do they have some type of device that can tell how long a car has been still?

Answer 1

When I used to park on the street they would have someone that would come around and chalk the tires to check for movement.
