Automatic Chicken Doors: Inside or Outside?

[jennyf]

Those of you that have automatic chicken doors, did you install inside or outside? I'm seeing that many seem to recommend outside installation but couldn't a raccoon theoretically pull the string? Or not without a thumb? Am I overthinking this? Mounting outside would work better in terms of our coop design. I've read probably 100 reviews of various externally mounted doors and no reviewer seems to have had any raccoon issues.

I have the Ador 1 door, mounted on the outside. It's been in use for over a year, no issues at all.
