Not sure if what I have is the same (mine is a KGuard 4 cam solution) but I was trawling the web for the same busybox version and found this. It didn't answer my question but I thought that I could help answer some of the questions as my box seems OK, it works remotely and the backup files too.
From my experience you can get it to make a sound but it's pretty useless, it just beeps and for my money I don't want it to beep because if someone has broken into my house I don't want any thieves to work out where it is. Mind you I use it for internal motion detection, the lowest sensitivity of motion detection seems too high for external cams (18m cable IP66 cams so can be placed outside apparently with 10m IR night vision).
As for the backup files, these get downloaded to c:\DVR but there is a feature on the ActiveX web interface to convert to AVI which is a button on the Replay tab at the bottom labelled "264 to AVI". This then creates another file that won't work with Windows Media but will work with VLC Player (http://www.videolan.org/vlc/). Might not be on your interface thought.
Also the box I got came with Windows Mobile and iPhone apps, the Windows one looks like freeware but can't talk about the iPhone one as I don't have an iPhone.
Like I say perhaps my box different than the ones discussed here, I don't know but it sounds like it's a generic re-branded solution with different cameras. The reason why I got here was because I was looking for a way to disable email alerts remotely in some way. Looked at cracking the protocol from the ActiveX app but it's a little complex. I emailed KGuard and they aren't helping and I'm not surprised so I'm back to an email block via my ISP but unfortunately the box queues up at least 30 minutes of emails so I'll just have to put up with this at the moment.
Hope this helps anyone.
