The door is the front entrance to a small warehouse. It's in a mixed use office/industrial area, so when they built the building, all the front doors were put in so it could be an office or showroom, but they are using for warehouse. It is so they can leave it locked and unattended. Then I will put a buzzer in too. The active side has a manual latch that can be activated from the inside for egress.
The door has an upper glass panel and lower glass panel with a frame member across the middle with a hand bar. I figured I'd fish right down the center (I hope it's a clean shot).
I'm kind of leaning toward the armored cable loop, but undecided right now. Thank you both again for the helpful input.
