I was recently asked this question by a client and i have to say i wasn't able to answer this question on the spot. However after a little research it is gernally accepted that a USB cable can work up to 16 feet which is around 5 meters. The problem the client had was it wanted to stream video from outside the premises to a computer in the middle of the office.
For this method i suggested an ethernet camera to the client, however they insisted they used the USB connected camera. To enable the device to work over this distance they needed to puchase a USB ethernet exnteder. Essentially this takes the USB signal and converts into data that can be sent over a ether net cable (upto 105 metres) and then it converts it back to usb. The only problem we had was using this method it reduced the quality of the hd usb camera. It was no longer possible to get the full range of resolution which was a bit poor.
The reason the maximum distance is set at around 16ft/5 meters is that there is signal degredation after this point. It doesnt mean that the device would not work however reliability starts to drop away and so they have this as the maximum.
Whats the Maximum length a USB Cable can be? 16ft / 5m
