Animal Proof PIRs

["Mark Boyce" <mark@xxxxxxxx>]

Morning all,

I'm on the hunt for some external PIRs for a balcony which
are bird proof.

We recently had someone get over the roof and drop down
onto the balcony and through the open doors.   I hadn't
previously placed PIRs there because of the number of
birds we get sat there.

Anyone got any recomendations for Pet proof PIRs that
actually work ?

Cheers

Mark.
