Summary: Bought 8 of these for a surveillance role at work. The initial test camera did not pan and was returned. The subsequent 8 have thus far worked well. They are a bit cheap feeling and the small zoom factor and less than sharp focus is what got it 3 stars instead of 4. PoE works well and the interface is pretty intuitive. On the other hand, Vivotek has yet to fix the RTSP timeout issue when using anything other than it's viewer. You get 60 seconds and then it times out.
