SECURES LIVES & FACILITIES

Keystone is a trusted provider of Bogen Nyquist. With over 40 years of experience in designing and installing intercom and clock systems, we offer an integrated solution tailored to your needs. Telecenter U combines emergency notification, event management, and everyday communication in one user-friendly, web-based platform. Our expertise, coupled with trusted manufacturers like Bogen Nyquist, ensures seamless message delivery across your educational campus or factory floor.

Verifying visitors with a simple voice intercom is functional but not always reliable, especially if there is a lot of street noise or other interference.  With a video intercom system, the guesswork is removed.  You will always know who is entering your facility, which is as easy as pushing a button.  Intercom systems can also be used to communicate more effectively between offices or other areas of your building.

Our advanced nurse call systems are designed for Critical Alert patient monitoring and notification. Give residents an easy way to call for assistance with just a push of a button. With multiple alerts, your residents can rest assured that every concern will be addressed in a timely manner. Need to upgrade? Replacing your outdated system?
