Infrared alarm?

[audi321]

Hi all, I’m looking for **something** which sends a beam between 2 points (around 10m apart) and if the beam is broken then it sets off an audible alarm (not in the same place but another 20m away.

I don’t want a general ‘zone’ type IR detector, it must be a beam of some sort (to small avoid animals setting it off) so I’ll set it up around 1m off the ground.

I’m obviously searching Amazon for the wrong words as I can’t get anything to come up.

What would it be called?

Isn’t that just 2 electric gate sensors? There’s no alarm or power or control unit or any kind?

one of these connected to a siren?

Cheers but I’m looking for something all in one really. Power supply, alarm, control unit, sensors.

I thought it was just me but maybe something like this doesn’t exist at all

Perfect!! So it’s called a ‘perimeter alarm’. I just need to find one that’s not £200 now. Cheers

Managed to find some a bit cheaper and can upgrade more sensors later down the line if I need to.
