Kantech KT-400 is an Ethernet-ready four-door controller that provides 128-bit AES-encrypted communication with the EntraPass system and is a highly secure solution for any security-conscious business. KT-400 can easily be integrated into an existing EntraPass system with other Kantech controllers (KT-100 and KT-300) or can provide the foundation for a brand new security installation. With an embedded Ethernet port, IP connectivity is effortless. Initially available with 16 onboard inputs and four onboard outputs, KT-400 is easily expandable to 256 inputs and relay outputs. The expansion modules are added using removable SPI cables with built-in connectors for quick connectivity.
