I've used my cameras (unifi, local storage) to 1) help a neighbor find their lost dog, 2) help me find my own dog after a contractor left a gate open 3) make sure my kid gets home when he bikes ahead of me, 4) watch a fed ex employee punt a box of mine, 5) watch local wildlife at 3AM - last night there was a racoon party in my front yard.

I will know when you buy your first house.
