Ive been wanting some kind of home cameras for ages, and I really dont know what Im doing but I bought this on a whim:
http://www.gearbest.com/ip-cameras/pp_193393.html?wid=3Chinese IP camera, 720p, two way talk, microSD motion activated recording, IR night vision, android and iphone apps, motion alerts ..... £23 delivered from their EU warehouse!
Its a bit limited with stock firmware (RTSP disabled) but there's
custom firmware that fixes some basic issues.
I absolutely love it. Budget chinese tech is awesome (even if the apps are sh*t).
