When I last looked into a PTZ capable outdoor camera, the best advice was that I can probably get a supported camera module but I would have to source my own enclosure, lenses and everything else. There are standard dimensions for lenses and mount points ...etc but it was not going to be a straightforward thing that I could bang out in a weekend.
> We have a bunch of ptz outdoor units supported by Thingino. Check out thingino.com for the full list of supported devices!
Compared to when I last looked ~ a year ago... yeah, the list certainly has gotten longer.
For anybody else that clicks, all of the outdoor cameras are all WiFi based, though. The dream of "at least 2K, PTZ, PoE and rain-proof" is still a pipe-dream :(.
