A wildlife PIR triggered camera might be more useful for your
application - that way you have some video of the scrotes.

I was going to investigate a(n invisible?) break-beam sort
of device that could be set higher than most ground
dwelling creatures and below the typical flight line of a bird.

Wouldn't work here, lots of birds zoom thru my trees at well
below human head height. Amazing how well the manage
to avoid crashing into anything at the speed the zoom thru.

That connected to a GSM SMS dialler so that I can
1) remotely view the CCTV then 2) potentially call the Police.

Yeah, that's what I'd have.

Nothing the Police like to know better
than the scrotes are still on the scene. ;-)

Yep.
