I see a lot of new cameras on the market with some interesting features, but getting real definitions and answers is difficult at best. When I see a 3x Varifocal Sync Focus (Pan Focus) Lens Dome Camera with RS-485, my guess is that it has a 3X-Zoom that would be adjustable via RS-485, other than that, I get a little confused with the "Varifocal Sync Focus (Pan Focus) " which appears to be all one term. Does anyone have a good definition of these terms?
Thanks
