When it comes to protecting your property, intercom and telephone entry access control systems are great ways to manage who enters the premises. They are communication devices designed to limit who has access coming and going. With both, someone shows up to the front of the property, uses the device to communicate with someone inside, and the latter decides whether they are allowed to enter. While they're often used interchangeably, there are key differences. Here's what you need to know. 

What Are Intercom Systems? 

Commonly seen in homes and single structures like schools, hospitals, or offices, intercoms rely on two-way circuitry. Although most people think of it as a voice-only technology, these entry access control systems can also be set up with a CCTV video system that runs alongside. They can be used simultaneously, but they are not immediately connected. The intercom is a standalone system.

What Are Telephone Systems?

As for telephone entry access control systems, they're more popular on larger properties like apartment complexes, gated communities, and multi-tenant office buildings. They have their own network on the premises, with the base station at the entrance. With telephone systems, video can be directly integrated with the system.

Which Should You Choose?

From the user's perspective, both systems operate in practically the same way. Because of this, consider the size and spread of the property. By and large, most residential customers will benefit from an intercom, while larger complexes can benefit from a telephone system.
