Should normally be set to 0 or 1 for video/TV cards, and -1 (disabled) for USB and network cameras.

This parameter is really used only with video capture cards that has more than one input.

However if you set the input number to e.g. 1 for a USB camera motion writes an error message back. If you set it to -1 it does not give you any warning.

If you have a video capture card you can define the channel to tune to using this option. If you are using a USB device or network camera you should set the value to the default -1.

Many TV tuner cards have the input channels: TV Tuner = 0, Standard composite video = 1, S-VHS = 3. Other have TV=0, composite video 1= 1, composite video = 2, S-VHS = 3. It is recommended to set the parameter to -1 for USB cameras as your first try. For video capture cards input 1 is normally the composite video input but it may also be 0. Try both until it works.
