Access Control Enterprise Server is server-client architecture based software solution for managing the users and their permissions to the premises, controlling the doors and having the video footage from surveillance cameras displayed right within access control software. The Enterprise edition manages access related events, such as Access Allowed, Access Denied, Access Expiration, Access Unknown, Denied Time Zone, Egress, Duress, Alarm, Arm, Disarm, Network Loss and Recovery. Upon the incident, it is possible to investigate the situation with just 1 click that pops up a video playback of up to 2 cameras per door, delivered from NVR 3 or ENR-series Standalone NVR servers. All the past events are easily searchable by event name, card number, card format, member name or access control device. The following access controllers and door stations are supported: R11-20, R11C-30, R12CP-30, R21CF-30, Q950, Q951.
