The present invention is an access control door controller which utilizes three relays, 16 alarm inputs, tamper switch, a Weigand reader, a RS 232 reader and a IP core module to enable access control alarm monitoring, inter locking of doors and/or energy management for a room with the help of a software. The present invention utilizes a distributed communication (peer to peer) thus creating a door access controller System network with a truly distributed intelligence permitting exchange of information between all controllers which may be situated in a single site or over multiple sites connected on a common network. The full system can be configured on the widely used TCP/IP network thus avoiding the need for extensive wiring traditionally required for Access Control System. The controller, with its associated software can support multiple types of readers and can directly interface IP cameras for an integrated TCP/IP based Access Control/CCTV Solution.
