We've gone over quite a bit.
The houses are laid back, fronted by tall vegetation/obstacles for privacy, and the streets are stunningly dark due to the low-light ordinance. Neighbors cams don't extend out to pick up cars (which would be an IR washed out blur at that distance, IR only goes so far, you can see how much detail is lacking in the washed out footage of Latanas guy w/o the backpack, and that was what 12 -15 ft away. Even if you get extra IR emitter spot lights it still washed out in the distance which is why I keep bright spot lights on cause night cams are a great disadvantage and work in short distance). Several neighbors interviewed said they didn't have cameras at all (mostly elderly) and those that did said in interviews that they would not pick up any cars in the obscured views of the street, and cars never motion detect for them.
I have dozens of cameras on my property, which is laid back like NG with privacy landscaping, including 4K POE and 4K wifi cams 100 feet down my driveway and I couldn't pick up a car on any of them, and I have commercial style spot lights. In the dark, forget it, 35 feet away in the night relying on residential IR cams you wouldn't make out a make or model...and if they drove up with their headlights on at the cams like a delivery driver, the footage would just be a bright glare (best way to obscure IR night cams, shine a bright light directly at them,) Pointing a powerful IR emitter light at any night cam will also blind it, and neighbors would not see any light.
NG's area was a blind spot, even the main street DOT cams at intersections nearby did not record, according to police (and Tucson does not have police or flock cams on the roads).
