Intercom systems are used in multiple locations for a variety of functions. On a smaller scale, a business that keeps the doors locked at all times can use an intercom system for visitors to notify them and to remotely open the door. Inner office communication is another application for an intercom system, allowing co-workers to communicate from their offices. Today's technology also include video intercom systems which allow the user to see and hear who is requesting entrance. The addition of video to the intercom system adds an extra level of security when it comes to whom is being remotely let into the facility. Wether it is stand alone or IP based, IACS Inc. has the experience to install all types of intercom systems to fit the needs of our clients.
