Recording home security camera directly to CD-Rom
 

I have been trying to rd my home security camera dily to a
CD-Rom, instead of a VCR tape. Right now, I rd it into my hard
drive and then I copy the hard drive to CD-Rom. I would like to rd
it dily to a CD-Rom.
Will appate any suggestions. Thanks!

You'll need to utilize packet writing software to do this...
Roxio's version is called DiCD.
It's basically software than allows you to treat CD/R and CD/RW like a
floppy.  Though it is a little more sophistcated than that...
A good explanation is here

accessable concentric tracks, a CD has a single spiral track.  I
believe the process is to open a session, buffer the data, write out
the contigous data, then close the session.  You can't really write
some data, capture more data, then write some more.  If the buffer
runs out before the new data is ready, you have an unreadable CD.  If
your software continously updates a single file you won't be able to
do this without stopping the update, copying the file to CD, then
starting a new update.
You might be able to use the NT event scheduler to stop the rding
application, copy the file to CD, then restart rding.  I really
doubt pointing your application to a di CD will work.

For Disk-at-once rding this is true...
From Roxio's FAQ..."In Disc-at-Once rding, one or more tracks are
rded without ever turning off the rding laser, and the disc is
closed. Disc-at-Once rding requires a blank disc, and cannot be
used for multisession."

This is psely what packet writing does.
From Roxio's FAQ..."Packet writing is a method of writing data on a CD
in small increments. DiCD software supports packet writing in
accordance with the industry-standard UDF specification. Not all CD
rders support packet writing; (see the rder's manufacturer's
specs and the Recorder Support Database for more information). Not all
current CD-ROM drives can read packet-written discs.

If

 the buffer runs out of data before the session is closed, this is
cor.
But there can be more than one session on a
CD.

Can't argue this one...and to be honest, your suggestion below is
probably a better alternative, since DiCD requires alot of
overhead.  Up to 100MB per CD.  Besides, writing dily to a CD,
depending on video quality won't result in much rding time
anyways.  Someone would have to be replacing disks every few minutes.
Full motion DV requires about 3.6 Mb / second or about 3 minutes per
CD.
