THE BUYING GUIDE

Think beyond the door station.

Video intercom selection starts with how visitors call, how residents or staff answer and how the entrance is released. The door station, indoor monitor, power arrangement and any management software must suit the same installation. Check the exact architecture before replacing a single part: IP, two-wire and other intercom families are not automatically interchangeable.

Start with the application.

Describe the job, the installation environment and the equipment already on site. Compare the exact model specifications before choosing; a collection name alone does not establish compatibility or included features.
