Pros and Cons of Different types of IP Intercoms
There are two types of intercoms. The first type connects many intercoms to a number of central computer stations, while the second type connects one intercom to many smartphones or VoIP phones.
In general, IP intercoms can be used to notify you that someone is at the door or provide communication between many locations (like schoolrooms) and a central office. The intercoms are all wired to the local area network.
These complete systems enhance your total security, assuring a safe environment in this uncertain world. Here is a comparison of the different systems available.
Intercom to Central Station:
This Digital Acoustics IP intercom connects to the network and provides two-way audio. The system requires one or more central command computers that are attached to the same network. It is used in two types of applications. It can be used at doors to control access, or it can be used in various locations around an organization to provide general communication.
In the door control application, the intercom can be wired directly to an electric lock to control door entry, or it can be connected to an IP door access control reader. This network-attached intercom system is usually used by large organizations that have a designated person(s) to control access to the facility. You can also have more than one person (and computer) controlling entry. When a person pushes the call button, a sound at the computer notifies the control person that there is a person at the door. The control person can talk to the visitor, and make a decision to grant entry or not. Authorized people can gain access using their credentials or even using biometrics (like a fingerprint reader), while visitors can be monitored for controlled entry.
In the centralized communication application, the intercoms are used to communicate back to a central office. For example, classroom teachers can communicate with the administration office. When the teacher pushes the call button, an alert sound occurs at the office computer. The intercom system can also be used to listen to a specific classroom at any time. This type of intercom system can also be part of a central emergency alert system. Take a look at our network attached PA systems for more details about paging systems.
Audio-Video Intercom to Central Station:
This audio-video intercom system is an extension of the audio-only intercom. It adds the ability to display video, from an IP camera, at the central intercom command station.
