As the title says, I've a teenager who's being a teenager ... sneaking out, sneaking people in, and sneaking into my bedroom. That said, I'd like to setup some cameras and put an end to the shenanigans. I suspect my wife will let me spend between $500 and $1000 to get things under control. As far as indoor cameras are concerned, I need one camera to cover the main entries of the home, one for my bedroom, and one for my work shop. As far as outdoor cameras are concerned, I need at least 4 cameras to cover the main entries and 8 if I want to cover the bedroom windows of the younger teenagers. I'd considered the Nest IQ for outdoors because of it's AI facial recognition but heard there are better cameras for the money and cannot see myself paying a re-occurring service of $450. I'm an IT guy so I have no problem configuring cameras, setting up private VLAN, or creating scripts to process their streams and push to the cloud, etc. That said, I'm thinking a NVR is a better choice with IP cameras?? Are there any cameras which have good AI facial recognition and a movement alert system so I can be alerted when people are entering or exiting my home at night without tons of false alerts? FYI - I have a PoE switch and plenty of RG6 and CAT6 cabling so wiring the cameras aren't an issue. It would be nice to see all the devices from my iPad. It could also be nice to have TPZ but not critical. What are your thoughts? Please help me find a good system by Black Friday.

I have LED motion lights above my entries which I think illuminate quiet well at night. Without having owned any cameras, do you think the Dahua 5231 is a better choice than the 5831 4K? If the LED's provide enough light and complete darkness isn't an issue then perhaps the 4K would give the better picture?
