What Is The Best Way To Position Cameras For a Stairwell Shot?

Just looking for people's perspectives on coverage of corridor & exit stairshafts. I have 6 stairwells, 10 stories each, not unlimited budget.

My thoughts are:

1. Best view of face if mounted on wall, however it seems like a waste of a camera view as it is not going to capture much except coming and goings.

2. Likely get a decent view of face when people exit from the one direction, might get a view of people when the leave from the other direction depending on how the turn into the stairwell. Also get a good view of what is going on down the corridor. Supplement this camera by ensuring that there are cameras at each ground level exit from the building capturing face. This way at least you can put the story together using the multiple views.

3. Probably the best overall, but doubles camera/licence count.

4. Advantages of #3 but less cost? Is this the best solution?

5. Others?

Thanks
