I have recently purchased a service station (petrol/Gas station to some) with attached mechanics workshop etc. I am looking at setting up a monitoring system for the forecourt as well as other parts of the property. We will do zone motion detection at set hours but constant on setup.
I am seeking some guidance if anyone here has setup anything similar or has some good hardware/setup pointers.
I am in New Zealand so may find some of the hardware not always easy to source. My early though was stick up a number of IP Cameras but after reading the extra CPU utilisation requirements I need to take a step back and properly plan

A related question for the forecourt cameras, is it possible somehow to do OCR and record number plates?
