Okay, that immediately removes Ubiquiti's frankly somewhat toyish gen-1 airCam which, while being more or less megapixel and not TOO bad on video, don't have IR LEDs. And, as I have now had it thoroughly drummed into me by CCTV software recently, NOT all IP cameras are well supported in the various packages out there. But
Hikvision tend to be well represented, what would you say to a
wee IP66 PoE-powered bullet that really comes at a very nice price? Interestingly done video of (some of) its
abilities here; and product page
here. And, for your interest and consideration, there
are two dome cameras in the same price range, before it starts to get to be ...more. Note that the dome cameras are 1.3MP and 2MP respectively; they don't have IR LEDs but they also see down to really low light levels and while, for now, I only predict/suspect it may work, there's nothing to stop you from 'lighting' up the dark at night with an IR illuminator.
iSpy's a really interesting FOSS tool, and I'm busy working my way through it (too). A more grown up approach, still free, is available in
XProtect Go ..and BOTH systems support/recognise Hikvision cameras (I checked).
