Management/owners have no motivation on their own to install this. They have already satisfied their insurance company by having a locked gate, any kind of locked gate. It's a plus that they can put in their consumer ads. And that's it. They have no pain.

Individuals have the pain.

Total guess, if you can get enough individuals to like it for free or cheap, then the hue and cry may motivate a manager somewhere to subscribe for $WORTHWHILE.

Or you might sell it to the lock companies.
