For may years my favourite stand-alone PIR was of all things the Wickes 110-degree own-brand one - it has a decent amount of wiring space, included a PE parking terminal, three-point mounting with deep standoffs so easy to fix to uneven walls, two separately grommeted entries so easy to loop through, easy to adjust (both in position and light level/time) and relay output so no problems paralleling it with other sensors or override switches. The only thing I didn't particularly like about it was the clip-on lid - but it was reasonably difficult to remove so not really a safety concern. Best of all, over perhaps 15 years never had a single one fail on me. Of course they've stopped doing it now....
