Did anyone ever use one of these products from this company.

I heard they are good, but here they don't say CPU speed, http://www.vguard.net/down/spc/en/VGEMBDSPC_EN.pdf.
I want to know which how good they are compare to what zm has? if anyone has ever used it or seen it, I would appreciate it to hear any comments.
they also have H.264 technology, which I don't really understand. does anyone know what that mean.
thanks.
vguard product
I have been using the Vguard VG4C - RT4 card for a couple of months and I am very impressed.
Card uses TI DM642 DSP so can easily compress all 4 channels doing 25fps per channel at 704X576.
H.264 is advanced mpeg 4 (part 10) compression standard aimed at giving higher quality for smaller file size than mpeg4. Vguard uses an H.264 codec called SMICT. In practice the results are better than anything I have seen from any other card and better than some very expensive standalone DVRs.
The hardware compression chips do all the hard work so you don't need a fast PC – recording all four channels at full res, all at 25fps and with motion detection running, I only use 10% CPU on a 2.4Ghz celeron.
Card is expensive in the US ($600) but only £200 in the UK (makes a change!)
Software with the card is pretty good with a few minor quirks but very stable. Manual is pants.

Have not had time to experiment as the RT4 is currently being used in anger! in an XP box.
What interests me is the fact that Vguard also make Linux embedded standalone machines. I am guessing they use the same RT4 card in those machines.
Would be nice to harness the power of the DM642 with ZM but not a job I could do.
