    That's an excellent suggestion - I use such a system on my little cnc
    machine and sometimes on my watch lathe and, apart from being more
    restful on the eyes, it lets me see from angles I can't usually get
    at. I use the little wireless 'spy'/security video cameras from Hong
    Kong which cost me around 20UKP ($40) for the colour camera, wireless
    receiver and wall wart. I use them connected by a wire to the monitor
    though as motor noise affects the wireless signal. On the cnc machine
    I us a 7" dvd portable player as the monitor as its dvd drive is
    broken and it is a convenient size to mount next to the machine but
    the 15" LCD computer monitor I also use is even better. The lenses on
    these cameras are easily adjusted as they are on a screw thread and
    they will screw out to focus down to about 1/4"!! Depending on the
    make, they will work in fairly low light levels but if you choose the
    'pinhole' type, the picture will degrade as the light level falls. 

Best wishes,
