Intercoms for IP Systems

Intercoms for Door Access Control

The IP intercom is a device that connects to the network and provides two-way audio communication to a central location. It is excellent for controlling visitors at the door. Many IP intercoms use PoE for power, which makes installation easy.

Intercom Management Software is used to manage and talk to many intercoms. For example, the person at the computer can control door entry or talk to each classroom in a school.

There are several types of IP intercoms. There are indoor and outdoor type IP intercoms. Some intercoms include video so you can see the other person.

Intercoms can be used to control door access. Network-attached IP Intercoms can connect to a central safety control person. For example, the apartment intercom connects to all the tenants to control visitors.

Kintronics provides a choice of intercom systems, from simple audio units to advanced systems that include integration with access control and IP camera systems.

How the IP Intercoms Work – The Systems Diagram

Electric Door Locks

Electric strikes or magnetic locks are required to control the door. There is a choice of electric strikes or magnetic locks (maglocks). In many cases, the electric strikes are better to use because they stay locked even if power is lost. Maglocks are used for special situations such as when it is not possible to use the electric strike or when you want to control access from both directions.

Electric Strikes

The strike replaces the fixed strike plate in a standard lock. This electric strike latch allows the door to close and latch just like a fixed strike would. To exit from a secured area, the door can be opened by using a knob or level.

Magnetic Lock

Magnetic locks are used when electric strikes can’t be used. They are also used in high-security areas where you need to monitor the movement of people. Since people are required to use their access cards in both directions, you can track who enters and leaves a secure area. Maglocks should be used with care because they prevent people from leaving an area as well as entering an area. Special exit mechanisms are usually required to make sure people can exit in emergencies.

Kintronics provides total integrated solutions that include IP camera systems, Video Management Software, IP door access control readers, door access control software, electric locks, and fully integrated video intercoms. Everything attaches to the network, making installation very simple.

Which Intercom is Best for you? Here are the Pros and Cons.

These new intercom systems connect directly to the network or integrate with IP cameras. Powered by PoE, they are very easy to install. They are especially good for multi-building organizations since they connect wherever you have a network. They also open an electric lock (with additional relay) or the latest IP door access control readers creating a complete door control system. The video-enabled door access control system provides complete control of your environment. Authorized people can gain access using their credentials or even using biometrics, while visitors can be monitored for controlled entry. These complete systems enhance your total security assuring a safe environment in this uncertain world.

When someone comes to the door, the visitor can push the call button which notifies a person at a computer. The control person can talk to the visitor and make a decision to grant entry or not. Here is an overview of the different systems available.



Connects to the network and provides two-way audio. It connects to an electric lock or IP door access control reader. The system uses Talkmaster intercom software on your Windows computer to provide notification and two-way audio as well as remote door release. The intercom connects directly to the network and can be part of a central emergency alert system. Take a look at our network attached PA systems for more details about paging systems. This system does not provide as much protection as those that use video.

They are best used when you have other video surveillance cameras that are viewing the door.


This intercom integrates with an IP camera. It includes easy to use CAT5 connections between the interface unit and intercom panel as well as the IP camera. Leads from the interface box, with 3.5 mm plugs, connect directly to the IP cameras audio in and audio out connectors. Power is provided by PoE and powers both the camera and intercom with a single drop point, making this a very easy to install the system.  It can easily integrate with an IP door access control reader, providing both automated and manual control of all your doors. The system can be monitored and controlled using Windows Explorer but requires Video Management Software (VMS) to provide doorbell notification. When these systems are used with an IP camera that is viewing the doorway, they provide more security by allowing you to view and identify visitors.
