Verkada’s Controller lineup offers 3 different kinds of Controller for any kind of use case. The AC42 4-Door Controller is great for small- to medium-sized deployments where space, scalability and simplicity are important drivers. The AC62, meanwhile, is an enterprise-scale Access Controller that can be used in large-scale enterprise deployments with tens or even hundreds of doors. Finally, the AX11 IO controller is great for access controlling elevators, IO devices and other inputs.
