I upgraded to Ver3.1.1 of D-ViewCam software & now have a functional home surveillance system. Very Cool. It has a few quirks that I'd like to understand & hopefully fix, but for now its up & running & faithfully recording motion events around the house 24/7.
I only have a single camera system (DCS-920 wireless + Cisco E3000 Router + Compaq Laptop) so far, but after a few snafus it's working as I hoped. I intend to add more cameras in time but its a solid start. It seems very easy on disk space (default mode). I started with 60G free on my hard drive & after the first 24 hours of events I still have 60G free. So based on the recycle feature I should be able to record for a VERY long time before re-cycling. More cameras will affect this, but based on the size of the files so far I should still be able to record for a VERY long time with multiple cameras. Also very cool.
If you're curious about a useable home or business surveillance system this is very practical. Give it a whirl.......
