Great thank you. Do you have any suggestions for the 2 cameras monitoring the driveway?
Camera Placement?

Are you talking about my driveway cams? If you are, they gave great face ID's on door checker at 3:50am back in June. Cop said, 'Yeah, I know him'.

Remember to test the suggested positions.
For test purposes:
1) Find a friend to act as a prowler and wear a hoodie and baseball cap.
2) Test multiple times during a 24 hour period. walk, walk fast, jog - do not look "up" at cameras.
3) Have another friend / significant other review footage and attempt to ID suspect
Also when we state "too high" it is really a question of getting enough pixels on the subject at a good angle to get a reasonable chance at a facial ID image. So, if you are using a varifocal and have a tighter FOV so that you can get 100 ppf on the curb - then the cameras can be mounted a bit higher as long as you can still get a good angle for a reasonable chance at a good facial ID image capture.
Often people are attempting to get facial ID images closer to the cameras as they are using cameras with a wider FOV ( 90 degrees / 3.6mm ) and in those case you definitely want the cameras to be mounted lower ( 6-8 feet high is the general rule of thumb we're going by here.. )
Thus why I recommend the hoodie and cap test.
