Hi Everyone, I'm trying to find an internal detector/PIR that has a 180 degree range.

Because of the irregular shape of the room I cannot put a PIR in the corner so am looking for a detector that can be put in the middle of a wall which can detect intruders both to the left and the right. All of the detectors I can find are around the 90 degree range.

Thanks in advance for all the help.

what about putting two back to back to cover 180 or install a 360 on the ceiling?

Hi Snowrides and welcome to the forum.

I think you may be trying to achieve something that isnt necessarily needed, why would you need blanket coverage, yes it is wise to have the alarm activate as soon as possible, but to detect every cm of a room really isnt needed.

I have a optex rx 40 in the centre of my lounge its a 90 degree detector but you cant get to anything of value without being detected.

Sensors can in theory do 180 degrees but a single element can only do so much, so you can have 180 degrees with huge gaps between, or 90

As has been said already either position for best detection, back to back or use 2 corners

360 masked?

360 in centre at wall, same diff.

True, didn't think of that what about a 360 mounted on the ceiling?

He asked for 180

Thanks Everyone,

I'd already thought of a few of the ideas being suggested, but the one that I like the most is putting the 360 on the wall.

I doubt I'll need to mask it as the other beams will just be aimed at the ceiling.

I still cant believe there isn't a 180 on the market, surely I cant be the only one after this sort of thing.

Been asked before, not being rude by DIY. We generally never see the need.

Glad to be of help

Hi Oxo,

Any suggestions as to a good 360 to put on the wall?

It's for a large kitchen diner so I'm guessing dual technology would make sense.

thanks again.
