Thank you all who responded to my original email. I passed the info and obviously someone got wiser and re-defined the inquiry:
Digital Video Recorder Input: 16 channels (A/V) / Multiplexer, Output: 1/4/9/16 simultaneously Video, 1 channel Audio Memory: HDD 320 GB Again I am not sure I understand the type of device "described" above. All I know is its a part of equipment setup. I guess this kind of device is expensive and the previous inquiry was intended for a cheaper "emulation". Can anyone give me hints what am I looking for?
