SDC IPPro® IP-based Single Door Access Controllers are now available with two Ethernet Ports for interfacing with an additional IP device. They allow expansion from one Standalone door up to a 100-door “Grid” without the headaches of costlier, more complicated enterprise solutions. Configure and manage every door from a single interface that grows with you.
