Several of us use Sharx cameras. I have five 3906 and 3924 outdoor wireless IP cameras. Yes, you can send images and video to a server or to local storage. And a lot more. Here's one of mine set to send a JPG image via FTP to my server every five minutes.
As noted, customer service is superb. One of the best in any business I've ever encountered. They are still supporting replacement parts on one of my cameras that is three years out of warranty at no cost. (IR Light ring)
They have a new Pan/Tilt/Zoom camera available, although it is not on the web site yet. Write to them at customerservice@sharxsecurity.com to find details and cost. It was in the $800 range, though.
