Have the 311PI already in use and have now even taken the 310PI to. The build quality is great and with the drilling template, assembly is even quite easy. The picture is great during the day and at night !! (Compared to 7011 Instar another league!) Have both cams integrated in the Synology, each with the profile of 311PI. Works great with full resolution H.264 and 15 fps, top! For me it works well with Safari web interface, but you should have an IE to Have ready security ..... FW update without any problem. Absolute buy recommendation.
