I purchased an old PTZ camera and housing that I point to wherever I've managed to park my car, it's an old coax system and the joystick/controllers cost more than the cameras do! However you can use a cheap rs485 converter from ebay and a bit of software called PTZ Controller that you run on a PC to move them around meaning you don't need the joystick
It has a 36x optical zoom which means I can park quite a way down the road and still get a close up view of the 110.
As for the DVR I have an old commercial DVR that can record from 16 cameras, I'm only running a few cameras and as it's currently set up I get over 2 weeks of 24/7 recording.
So far it's recorded one attempted theft of the 110, a raid by two minibus loads of police in riot gear, some kids who stole a load of tools from garden sheds, some bloke who received eye for an eye justice, and a few other burglars making their getaway.....
As you may have guessed I get the occasional request from the police to check if I've seen anything.
