Specialized Communications Tools

Products that fall under the Security Intercom category provide highly reliable and redundant means of controlling, communicating, paging and archiving events and vital information. Not only do they offer convenience in identifying visitors but also allow an additional measure of safety and security in various environments.

Security Intercoms are specialized communications tools used to enhance security and life safety. Although any intercom provides an element of enhanced security wherever it is installed, the units on the market offer the enhanced communication reliability that is essential to security. These intercom products offer features that make them of particular value to security system designers and allow them to provide their customers with the most effective and comprehensive security management solution possible.

Intercom systems play a vital role in, and enhance the overall security of, any facility whether it is a single home, multiple occupancy, business, campus or multiple site/building enterprise. The systems available today allow the user to communicate with visitors, staff and security personnel. They provide varying degrees of integration between surveillance systems, access control systems, and other security/control and life safety subsystems.

The manufacturers and products presented in this month's focus are leading the way in security communications by adapting all the cutting edge technologies you see revolutionizing other segments of the security and IT industries. These products serve a diverse range of applications, from single residence to enterprise applications. Their scalable design and interfacing flexibility enable virtually unlimited expansion, communications options and exciting integration possibilities.

The security dealer/system integrator can choose an entry point, so to speak, in the security intercom market. It is not, after all, a separate entity. Rather it is an integral ingredient in security, just as is the cabling used to connect these devices.

By examining the sampling of products, you should get a better understanding of what is possible. Let them inspire you to be creative on your next challenging project.
