securitywarehouse Posted May 11, 2010 Share Posted May 11, 2010 I have decided to upgrade my old PIRs, I have looked at the honeywell range but I think they are to big at 90mm long. Could you suggest a nice neat small pir that is not to intrusive for domestic use and of a good make. Is there a suitable pir for use in a conservorty.

Secware_Tech6 Posted May 11, 2010 Share Posted May 11, 2010 From a size point of view there are few sensors smaller than the IS215. I wouldnt recommend going any smaller anyway as there is then no room for cabling etc. they are 87mm (3.5") tall. The lens can only be so small (ideally the bigger the better) and once the lens is too small then other things have to be cut, ie range, stablility, angle of detection etc. Quote Link to comment Share on other sites More sharing options...
