I suggest you consider the
Amcrest IP2M-841E (re-branded Dahua) . It's ONVIF compatible, provides RTSP, is 1080p, IR, 2-way audio plus mike in/speaker out, has pan/tilt/digital zoom, POE wired or wireless and has alarm in/out, great with
Blue Iris, VLC, etc. Available in white or black for under $70.
I have installed 3 of its non-POE brother, the IP2M-841 and 3 of the 720p IPM-721 and all have performed without a hitch for close to 3 years now.
