In some cases, the intercom is the first communication with a party trying to enter your facility
The intercom allows security personnel to remotely gather information to determine access to the premises.
Audio-only Intercoms can incorporate connections to public address loudspeaker systems, portable radios, telephones, and to other intercom systems. Some intercom systems incorporate control of devices such as signal lights and door latches.
Video Intercom systems offer the enhanced functionality to enable the person being called not only to speak with the individual at the door but also see (via a CCTV camera) them as well. Additionally (if desired) this video and audio can be recorded. As with the above audio only intercoms, video intercoms traditionally report back to a fixed location.
Cloud Based/3G/4G technology not only takes the intercom from a fixed location connection to a full function mobile tool, but also can now provide building management reports and analytics.
Additionally, systems have the capability via a web portal to send building-wide messages, update tenant records, and record photo/time-stamp access events.
Mass Notification Systems, Emergency Communication, Blue Light Systems, Area of Rescue Communication systems provide the ability to communicate through multiple forms of notification systems to push out a variety of alerts and warnings to prompt as many people as possible to react appropriately.
