After getting burglars this morning I think it is time to review our
security system. Fortunately, they didnt get away with anything as the alarm
went off after they opened the front door (presumably they were getting an
escape route as they entered through a kitchen window). Now because we have
a cat, we tend to leave off the zone that was the entry point - there is a
PIR in this zone which the cat has set off before. Also in this zone is a
door contact on the back door and a vibration sensor on the window they
entered through - I expect they wouldnt have got in had this zone been
You tend to get complacent about security when nothing has heppened for a
long time but this has made us take a bit of notice. So I was thinking about
rewiring to put the pir on its own zone (we only have 4 zones so a bit of
juggling would be needed) which we can leave off if necessary while still
protecting the doors & windows. However, I was just looking at cpc and they
have some 'animal resistant' PIRs which wont be triggered by an animal up to
35kg in weight. Has anyone used these devices before and are they really
resistant to my cat wandering round (while still picking up a person!)? Here
is a link to them...
Some give you a choice of lenses - the idea being to avoid ground level
and therefore pets. Of course, cats can jump up on things. But if yours
are this type you might be able to buy the lenses only and experiment.
A pal who had several cats avoided PIRs altogether and relied on shock
sensors. But had loads of false alarms.
IMHO, if you can be bothered with the work, sensors on all the external
doors and windows are pretty reliable, unless you are 'attacked' by a pro

The ones we have fitted apear to work on the infra red 'mass' rather than
poisition. I've lost the leaflet that came with them (naturally) but they
have an upper weight limit of something like 30kg and anything above this
will trigger the alarm. They appear to be fairly reliable so far as we
haven't had any false alarms from the cats jumping onto window sills or
worktops so they don't appear to be overly sensitive to position.
Contact your nearest Gardiner Security, and ask them for their range of pet
immune detectors. There are so many to choose from now, that each job is
becoming more difficult to spec' for. They've been in use for a good many
years now, and they have got better and better as time has gone on, so each
maker has their own style, shape and size to suit any decoration.
Yes ! They do work.
they do work - but not suitable for every location
less sensitive than normal pirs and need careful siting
they normaly require the animal not to be able to get within 2 metres of the
dont get confused with pirs with pet lens - these are not suitable for cats
you need animal resistant pirs. Note they dont call them animal proof
sensors! but they do work
much better to have its own zone as well
. However, I was just looking at cpc and they
