Do speed cameras use and technology to send you a fine or do the pictures get sent to someone to look through and send fines too the owners?

I'm familiar with 3 different vendors and the contracts they have with a couple of local municipalities.

In each case all vids and photos are reviewed by the company. Those they mark as violations are then reviewed by on duty or retired cops before the is a violation notice

The name of the cop reviewer is on the violation notices

YES. Both are true depending on jurisdiction.

ANPR (automated number plate recognition) does what it says on the tin.... 'automated' so all done via the technology

Hi so the data is collected via a wired system. it is analysed and it can clearly be seen that a driver was going over the speed limit by the white lines he is on when the camera was triggered. so those little white markings give a clear indication of what speed he /she was going. so they just look up the registration number and there is the address of the owner. the camera works via Radar on diminishing returns of it's radar signal similar to the air traffic control does with aircraft at airports.

Some systems use ANPR (automated number plate recognition) and the whole fine system is automated.

Many still just take two or more timed photographs and it's down to someone looking at those and see which vehicle is travelling fastest, then manually enter the fine info.
