3. not too concerned about id as we dont get much foot traffic in the area except people in the subdivision walking a dog or excercising (in a closed subdivision shaped like an eye bolt, 1 entry into or out). only have had 1 incident personally in 14yrs and that was just a guy climbing my 7ft wood fence to get away from the police.
No point having cameras if you can't ID. Your situation will be no different to if you find the door kicked in and didn't see what happened, in which case it's cheaper to find the door kicked in than install cameras that tell you what you would have found anyway without any further detail.
The whole point of cameras is to deter or capture. Preferably the former, if not the latter.
If someone does break in, cause damage etc, then without a means of identification, your cameras are useless. The best you can say to the police is a white guy in blue jeans and a white t-shirt was seen on my property. Given there's probably 10,000 people fitting that description in your city, even assuming the perp has come from your city and not travelled to commit the crime, the chances of anyone capturing them is near zero.
The whole point of CCTV is to be able to identify who committed the crime and have them arrested to prevent them from committing others (maybe repeats on you - a favourite in the UK is to burgle a house, wait a month until the insurance have replaced all the goods, then burgle it again!). Without the identification, you have nothing only a vague description. A red car, a guy in blue jeans and a tshirt. Pretty useless in the scheme of things. The identification gives you the ability to say it was a white guy, in blue jeans and a tshirt driving a red Ford Fiesta, with a Max Power sticker on the front fender, a dent in the passenger door and by the way, here's a good picture of his face, do you recognise him?
There are proven favourite cameras for this: 4mp Dahua 5442, and the current favourite due to it's night time performance, 4k Hik Vision
Hikvision ColorVu + 4K (DS-2CD2087G2-L) .
Remember however, as ST said above, you need to match the lens to your situation / prupose as even the bestc amera can't identify if the fov is too wide. Need a mix of over view and identification cameras therefore.
