You will need to try and place a cam where it has a close view of the driveway if you hope to capture the plate number. 720 res is barely enough unless you are pretty close. Hard to prosecute without proper ID. Unless of course, you know who it is already, then you just need a good face shot. This can get a little complicated legally, so be careful and thorough.
If you use motion triggered recording, and have a camera pointed at the street/road, be sure and set up the blockout zone to prevent inadvertent recording of daily traffic. You can also add separate IR flood illumination if what the cameras furnish is marginal. And remember that you will need access to power for each camera for its power supply, but the power cables can be extended if needed, provided the right wire size is used. They don't draw much current, but when the IRs run (at night only they come on) they triple or better in demand. I use 18/2 for power extensions up to 200 feet. I install quite a few cameras so might be able to help if you have questions.
And just for general information, you cannot install these for anyone but yourself without a security license. That's most states I believe. I know it is in Texas. Thanks to the Homeland Security Dept, that is the way it is.
