The only examples I know of are commercial systems, and specifically "cutting edge" commercial systems that are completely IP-based and cloud-managed. These are honestly kind of a disaster and I hope they don't catch on; they can be cheaper to install than conventional commercial systems (with ACU cabinets) but they achieve that cheapness by abandoning most of the reliability and security features of conventional designs. That said some of these get installed fail-open (e.g. loss of management means they stay unlocked) for fire egress reasons.
