A multi-door access controller manages several doors simultaneously from a single hardware unit — typically 2, 4, or more doors — reducing cost and complexity compared to deploying one standalone controller per door.
The controller uses TCP/IP for uplink communication to the access management software (iProtect or HIKVISION management system), and Wiegand or RS-485 for downlink communication to card readers and biometric terminals at each door.
Controller kits provide all necessary hardware in one box — controller board (KT-300PCB or KT-300), transformers, and rechargeable batteries. Multi-Door Expansion Kits allow adding extra doors without installing separate enclosures for each controller.
Yes. HIKVISION multi-door controllers store access rules and cardholder credentials locally, making access decisions autonomously even if the network connection is lost. Events are synced to management software when connectivity is restored.
A standalone controller manages 1 door independently. A multi-door controller manages 2–4 doors from a single unit with one network connection, reducing hardware cost and cabling complexity for multi-door buildings.
