Hi,


I need recommendations on equipment suitable to capture such action at a distance of 200 feet. Audio only at night would suffice as long as we can show video and audio of similar events during broad day light. The audio is the part that concerns me. I may have to have the equipment outdoors to get good audio.


Video camera with a date on while recording. Recording into PC with some
form of date stamp and pgp signature, encode to some format of your
choice.

Failing that, a couple of webcams (you can get them with pretty decent
lens now) pointing at the neighbours house which are sound/light
triggered.

D-Link's larger webcams use standard C-mount lenses, meaning that they're capable of accepting any standard video lens including telephoto. Barring that, get a video card such as the Hauppage or AverMedia and use a standard video camera with the appropriate lens.

You'd probably want a gun- or parabolic-style mic, as these are highly
directional and quite sensitive.  Visit your local electronic store
and find one that will work with your sound card or video card.

For recording software, you could try VLC, MPlayer or any other free
PVR software that works with Linux and handles V4L.  A google search
should reveal a bunch of them.  Many webcams now come with surveillance
software, although it's usually Windows-based.  Depending on the
package, it might run under Wine.  If you have VMware, all the better.
