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

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?

Zoneminder has very closely programmable Zones, to let you define
where you want something to trigger the alarm, and recording.

No PIR, just the camera feed.
If this is way off track, apologies.

ZM also needs a PC running 24/7..


No big deal when that can be a dirt cheap obsolete laptop.


and is a ****ty bodgey backwards step


And farting around with a separate PIR and sticking tape aint ?

Yeah, right.

You're so stupid you cant even manage to pick a decent IP
camera that allows you to specify a subset of the image to
monitor for movement and one that's been designed toi
handle sunshine/shade changes.
