We have a large garden and need a PIR unit (or preferably all in one unit/light) that will cover to the bottom of the garden. All the units from the usual suspects (B&Q, RS etc) seem to have a range of no better than 15m whereas I require detection at about 25/30m. I can't move the sensor position closer to close down the detection range and I don't really want to start laying cables to a remote mounted sensor before anyone suggests that! Does anybody know of UK source for a PIR that will detect at these sort of distances?
TIA
