I'm looking to mine the collective knowledge of this group.

In Feb. of next year my X-C ski club will be hosting the Eastern Canadian
Championships and we would like to have a video recording of the skiers as
they cross the finish line to get their bib numbers.  This will be a backup
to 3 sets of people visually recording the bib numbers as they pass the
line.  These people look at the bib number on the front and sometimes
because the way the bib rides up 9s start to look like 8s and things like
that.  We would like to have the camera looking from behind for another
view.

I think that 640x480 resolution with 20 -30 fps would be more than enough.
The camera will be mounted about 40m from the 15 m wide finish line so the
lens will have to be appropriate.  Light will be high to very high.

Temperature will be -25 to 10 deg C.  It will be mounted outdoors in the
elements.

We want something that is wireless - wired is too much risk getting ripped
out accidentally by someone.

It looks like some of the internet security cameras would do the job.  Most
are not weather proof and will therefore have to be put into an enclosure.
They will also require a power supply.

The big issue is recording and playback software.  We would like to be able
to record for about 8 hrs at a time and be able to play back certain
sections while still recording.  We also want to be able to look at it
frame-by-frame.

>From the few softwares that come bundled with the cameras that I have look=
ed
at in detail, both the playback while recording and the frame-by-frame
viewing seem to be issues.  It seems like the recording needs to be finishe=
d
before it can be played back.  Frame-by-frame doesn't seem that popular.

Does anyone have any experience with this type of thing that can point me i=
n
the right direction for software that would do this and would be compatible
with a wireless internet camera?

Thanks,

Gordon Williams
