I know Im asking for a lot here. But looking for a solid PTZ camera under $500 that has a spotlight on it, IR, tracking humans (dogs optional) that can also rotate 360 degrees. That is fully compatible with Blue Iris 5 and has a wide angle if possible
The spotlight would be gimmicky and useless at any distance.
Aside from that, look no further than the 49225 PTZ sold by @EMPIRETECANDY here. But you have to by from him as he is the only left that has it with autotracking.
