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 they manage
to avoid crashing into anything at the speed they zoom thru.

As I found with my cat came many critters can cross
such beams I had quite a few months, perhaps attracted
by the dull red glow of the IR LEDs.

But it is possible to get hybrid radar/PIRs that can
distinguish between cats and people by body mass.

Not they don't they just use the amount of IR
refected and where the reflection comes from.

Thats just one way of doing it.

I dont currently have any outside the house,

why not ?

Too easy to steal. I prefer the more capable movement
sensors that are a lot more programmable on what to
do time of day and what has happened recently wise.
Those arent cheap and are pretty easy to steal.

trying to keep them inside the house looking out thru
the 13 patio doors, but that means you can't use PIRs.

Yeah, we have what we call flying foxes which
are a bat. Mate of mine noticed them in my
trees. I had only noticed the birds and cats.

I'm betting there;s a posibility that
T i m has plenty of bats in his belfry ;-)

But which side of the belfry ?

A good question, that only he'll know the answer to.

No evidence that he knows anything about anything.

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.

Couple of stupid kids tried my main patio door
that is the front door with me not being visible.
I bailed them up and they were stupid enough
to try bluffing that they were checking that I
had managed to forget to lock it and were
going to lock it for me if I had forgot.


Called the cops and they were silly enough
to hang around waiting for the cops. The
cop who was well known to me came tearing
around the side of the house with his long
baton in hand.

Now there's a novelty

He/s built like a brick ****
house. The kids nearly died of fright.

Nice one that the way to do it.


That was after I had deliberately hidden in
the house and had left the car streets away
and grabbed the perp when he was inside
the house and called the cops. That cop had
been the police prosecutor for the first time
and had assumed it was one of those again.
