I have not but it may be the first one that I have noticed that states "....Being compatible with Onvif specification, users can easily connect it with your existing or new IP video surveillance system, it works with your NVR or VMS no problem."
Besides the claim of ONVIF-compatibility, the 1080p the h.264 specs, and the PIR, when considered together, make it noteworthy compared to others.
Hopefully Wi-Fi is not it's only method of networking...that would be the biggest fly in the ointment for me. Only $65? Put me in the skeptical category.
