The Flex Door and I/O module brings all the access capabilities of the key-centric CyberLock solution to doors: brisk communications, location graphics, access scheduling by the door and person, audit reporting of lock and key activity, and email alerts. Hardwired system hardware and CyberLock hardware can be mixed and matched to create a wholly integrated access control system. A facility can have door and I/O modules on their exterior doors, eCylinders on interior doors and cabinets, and smart padlocks on gated areas, all operating under one web-based access management software.
