The corner mount could cause an issue going out if that is the front door at the bottom of the stairs ( Look down, could pick up, and its better practise not to have the upstairs on entry route). So the ceiling would be better there.
Or put the corner unit in the opposite corner, that way you could go "back to back" with another detector in the other rooms.

When placing pirs to cover landings as mentioned be aware that they may catch people legitimately coming in the front door as mentioned but also
When placing instead adjacent to the bedroom doors to catch people coming up the stairs or going down them you have to angle the sensor slightly down . Otherwise it can be possible for someone to fail to activate the pir as they only have their head and shoulders showing at floor level when they are on the stairs.

But if they were coming up the stairs, without coming in the Entry/Exit then the hall detector or room would have caught them. If coming out of a bedroom/Bathroom then the landing would get them anyway. The whole point is to avoid the entry route as I said. If the system is well thought out at design stage then "traps" will be everywhere.
Not sure what point your trying to make here.
If you mean where there is a window halfway up the stairs as is common on a semi detached, the getting to the landing and or going down would be immediately caught by the afore mentioned.
If the detectors were fitted as per manufacturers recommendations there is no reason to have them tilted. Height and with certain detectors the position of the PCB compensate for this.

Depends on exactly what you are intending to detect.
If it is is people moving up or down the stairs then the location will be different to the location for detecting people moving along the landing.
Detecting people on the stairs could be best achieved with the the sensor mounted on the inside corner of the stairs about 4 feet above the stair. ( mid way between the red dots in your sketch ) .
If placed on the outside corner then people on the stairs will be walking towards or away from it most of the time they are on the stairs and that will not trigger the sensor until they are actually passing across the face of it as they go round the corner.
I am trying to workout if a ceiling mounted or corner mounted PIR is best.
Ive done a v crude mockup of upstairs hallway with some stairs graphics borrowed from Mr Google.
Any opinions on position?
Thanks in advance!
Just an update - 360 ceiling mounted is installed and works a treat, it catches just as you walk up stairs and then anywhere in the Landing. Its a Pyronix Octopus ( http://www.pyronix.com/octopus-ep-ceiling-pir.php ) and works a charm - is also a very small unit.
Thanks again for feedback.

LOL, you never mentioned a 360!
Have used them in the past, not bad little things. Thanks for getting back.

No worries
