A1710-B Network Door Controller from Axis Communications. This multi-door controller is designed to control and grant access to four doors via up to eight OSDP (multidrop) or Wiegand readers and locks. Up to 250,000 credentials and 250,000 event logs can be stored locally on the A1710-B. Thanks to PoE compatibility, only a single cable is required for installation and operation. Tamper detection provides an additional layer of security.
