I use to have a cctv camera on where my car are parked in the back yard, it was a PTZ network camera mounted on my 2 floor balcony door.
You can also get bullet shaped CCTV cameras that have a build in memory card slot and optical zoom, and are wifi so you can access it remote with a phone or tablet, and as i understand can operate alone so you dont need to buy a NVR for the storage of several cameras like i have a 4 channel Dahua NVR.
PTZ = Pan Tilt Zoom
NVR = Network Video Recorder.
Though for a NVR like mine + a camera + a 1 TB HDD you dont have to spend a whopping 2500 USD, you can probably do that for 500 USD if you do not go for the APPLE of CCTV equipment.
You can also get a wired camera for that matter and use your computer /laptop as the NVR, there are a few free CCTV software's for this approach, in that case you could get a 100 - 200 USD PTZ camera, this also allow you to pan tilt and zoom on the person if you are awake or maybe have been notified in some way.
Om my setup i used motion detect and had a zone about 4 feet around my car, and anything human sized within that triggered a alarm on my tablet on my bedside table,,,,,, but not sure if stuff like that also worth with the free cctv software's out there, as said i used a NVR box myself though it was also remote accessible from my PC or from my smartphone out on town.
There are a few good CCTV forums out there, i am sure those guys can advise even better, in here it is just a few of us that are dabbling in CCTV
If you park in the same spot you of course do not need a PTZ camera, in that case you can make do with a all manual camera where you just set the zoom level on a knob on the camera itself.
PTZ are nice to adjust, or if you are nosy you can turn it and look up and down the street, i once saw the police raid a house out back of my apartment,,,,, though a raid in Denmark are far from the same as in the US for good reasons
