I wish to install a basic alarm system to protect kitchen back door,
dining room patio doors (both at rear) and front door/hallway
downstairs and just landing upstairs which should be enough for attack
via any bedroom. Only thing is we have two cats 15 and 17 years
old,not overly active but still walk about and have access to all the
house. What sort of alarm system should I go for, PIRs seem simple to
source and install but are there any that ignore cats and only react
to humans?


Another approach towards security is to use laminated glass in the
openings big enough for burgers to get in through. They'll have to
bash in numerous imes to get through, each time making a breaking
glass noise. They soon give up, as every glass smashing noise is a
real risk to being caught. Repeated smashing is a dead give away. But
retrofitting this isnt really a cheapie option.
