I am very interested in SaaS in access control, but I have serious doubts that "HaaS" is going to work, at scale...unless it includes the hardware maintenance to the doors themselves. Here's why:
People don't like to "rent" their own doors. They don't mind paying for a monthly service that is tangible, like never having to do database backups or software upgrades, or never having to service a door, but HaaS sounds like just hardware rental. People will take a risk with one new model in this industry (SaaS based head-ends), but simultaneously with a subscribtion based door-hardware model?
What if someone decides not to renew a contract? Are you going to go in an remove all the door hardware (at your own additional cost)?
This is very similar to the mobile phone model in the United States, where carriers subsidize hardware costs through higher monthly rates, even down to Brivo's promise to upgrade hardware. However, access control product lifecycles are longer, and the improvements not as inherently obvious as with mobile handsets.
Also, who is going to "be the bank" in this scenario? Is Brivo or their integration partners going to bear the upfront costs?
I think this may see some success, but only with very small businesses; systems less than 10 doors, who are very sensitive to price.
