Hi everyone, anyone got an answer to this one. I have installed a webcam in my porch so that I can see who is at the door (Not secret or for security) I have used a cheap webcam and connected it with a 5m active USB lead. It works fine most of the time then suddenly get a load of background noise (Hissing sounds) I cant stop the noise, and cant close the program not even using Cont Alt Del. The only thing I can do is reboot.
Thanks for you suggestion Woodchip but I only put it in this morning so I would not think that is the trouble. Skyver, It is connected via an unpowered hub, strange as it may seem if I connect it direct a USB port it wont work. What I mean is the hub does not have its own power supply it is powered by the pc.
Given the length of cable, a good power supply is essential - your PC may not be able to provide the neccessary oomph on it's own. 500ma is the standard output from a USB port, it depends on the quality of the cable how much Resistance will sap that supply before it reaches your camera.
