Does there exist such a thing as a remote dual (or more) channel car DVR with small, unobtrusive, remote lenses? I see no point in having the DVR itself (with all the screens and buttons and such) hanging in the window, attracting someone to break in next time I park. The DVR unit itself can sit in the glovebox, or under the seat, until the need to review the video arises, and tiny cameras can be mounted on any window, connecting to it with thin, easy to pull wires. I tried searching this site and the rest of the web, but nothing jumps out... Thanks in advance!
