What are C@llDoor values and offers to you?
I am Risto, founder of C@llDoor. I had “access pain” with my rentals and I couldn’t find any suitable solutions in the market. Not any of the existing smart locks and systems were good enough for me.
Since I have been working with IT, security and access systems for 17 years already. I decided to solve this problem and I built C@llDoor system.
