getting Pd off with motion detecing IP cams sending 100s of emails of

One of the IP cams has 2 channels for I/O - so I'm pondering how to
send a signal to it to take a snap when something goes across the
cam;s field of view.
PIR would be perfect but a very narrow "beam" is required to make
sure I get the subject in the centre of the frame... and the IP cam
is not going to be happy with 240v up its I/O - so ???
low voltage PIR? what from where?
a normal 240v PIR and some sort of a relay?
something else?
Normal 12V PIR detector?
