Hi-O – the intelligent electronic door locking solution Hi-O (Highly intelligent Opening) is a new concept for electronic door locking solutions that simplifies installation, service and upgrade. Based on the ISO-standard CAN data communication network, it enables connected devices to exchange and share encrypted information. Any device, whether an electric strike, proximity reader, door automatic, can be connected to a network through a four-wire cable. When connected, devices can automatically start sharing information. Intelligence is built into each device, instead of one centralized logic unit, creating a highly secure plug- and-play system. Hi-O (from the initials HiO as in Highly intelligent Opening) is a scalable and future-proof system that allows all components in a door environment to handle access, identity control, code reading, alarms and service indicating, to be connected and controlled by IP-based technology.
