It is bigger than the standard fixed lens cameras, but smaller than the mini dome ptz's that Dahua makes. I haven't really messed around with it too much, but the IMO, the focus is slow responding
when using the motorized lens, and it seems you can only use the motorized lens in the web browser. The image and the 5mp is outstanding and the night vision is suprisingly impressive. I'm still looking for an outside home for this camera though.
