As a DIY installer I would like any advice available on positioning PIR sensors around my house, in particular a list of Do's and Don't would be useful.

I appreciate this may be classed as 'tricks of the trade' and whilst I am not trying to put anybody out of business, I do feel that there are a number of keen DIY installers (Myself included) who will never be able to afford a professionally installed alarm or perhaps enjoy the challenge of doing it themselves - but do want to do the best job possible.

Hi ,

Most detectors come with comprehensive instructions and usually recommend that you don't position them looking at large windows or above a radiator.Newer detectors are more tolerant , as sometimes there is no choice but to face a window.Keep your cables away from mains cables ,and choose a good quality detector and you shouldnt have any problems.

Regards.
