Some of these single board cameras have IR LEDs so they can work in
darkness.  Is there any need for IR filters on a B&W camera as there is
no colour balance to worry about?

They are ideal for a cheap monitoring system use a PIR movement detector
and some electronics to switch on the VCR and you can record who enters an
area.
