Can somebody please identify the make?

[Octopus]

So I came across this on Friday whilst wandering around a large garden. No obvious cables going to it and has what appears to be an aerial - so is it a radio linked PIR?

Can anybody recognise it and tell me who makes it? and what it is?



Thanks

Excellent, thanks all.

Saved me some searching - me thinks it needs a new battery!

that looks more like a receiver, trhe controll unit should have zones on it and facility to switch on manually.sometnig like this, an older one.:
