Re: Surveillance

[Joel Jaeggli <joelja darkwing uoregon edu>]

Decent dv camcorders  have ir modes (generally refered to as night mode 
or nightshot) that can record relativly high-quality video at very low 
light levels... They will typically also be able to accept external 
microphone's through a minijack and you can capture from them continously 
using their audio/video-output to something like a bt848/878 capture 
card or through a firewire connection. you can of course use the camera 
freehand as well whihc will make it more flexible... it's doesn't have to 
be terribly high-end such a camera can be had for < $500...
