I received the Avermedia NV3000 Monday and I've had some cycles to play around with it. I've only hooked up one camera so far, but I've got it set up for motion detection and remote access. It works well so far, but I can't stand that it requires IE to view its web interface. Stupid ActiveX components. With the 1 camera running, I'm using about 26% of the CPU and it's getting quite hot - about 66°C, but from what I've read, that's typically how hot they run under load. I was hoping to get away with minimal cooling but it appears I'll have to add another fan to the case. There's already a 120mm Antec Tricool in the rear of the case. I'm looking at adding an 80mm on the side panel to exhaust directly over the CPU. Hopefully, by this weekend I'll have 2 more cameras online.
The NSLU2 and CM11A have been deployed at our other house. The Airlink IP cam is also there. I've been monitoring the system and everything is working fine. I'll need to do some tweaking to the lighting schedule in the future and add a few more lights to the system at some point.
