Centurion® Defender

Portable, Flexible, and Powerful
For almost 50 years law enforcement agencies around the country have relied on dated technology such as Voice-Activated Radio-Dispatched Alarms (VARDA) and other devices to expand their policing reach. While groundbreaking at the time, technological advancements and evolving radio systems have made much of this technology outdated and less effective today. While a need still exists for technology (better than VARDA) that can improve response times and give law enforcement agencies an expanded reach, these needs must be balanced with oftentimes limited budgets to work with. Here Centurion® Defender was found by us.

The Centurion® Defender brings tried and proven policing technology into the next generation. With the most advanced sensor offering of any product on the market, there is no policing task too specialized for the Defender to tackle. Cellular connectivity ensures that the Defender will work wherever you may need it.


The Centurion Defender (the replacement of VARDA) leverages an internal cellular router to relay wireless alarms back to the Centurion Elite®. When paired with a cellular connection, the Centurion® Defender acts as a portable router of our 900mhz wireless sensors. The Defender receives the alarm packets then forwards them across the cellular infrastructure to the Centurion Elite®. The Centurion Elite® then receives the packets and initiates the proper response. Each Centurion® Defender’s health is monitored by the Centurion Elite® allowing customers to be instantly notified in the event a unit is off-line or if it has switched over to battery backup.


  • Portable packaging allows for limitless deployment opportunities and removes Elite use’s geographic boundaries, which is better than VARDA.
  • Allows use of all current and future wireless sensors remotely. Although, VARDA doesn’t support the new technological era by calibrating with the sensors.
  • Single law enforcement radio can support multiple Defender units.
  • Remote deactivation of alarms from the web interface.
  • Management of multiple Defenders can be done from a single user interface.
  • Unit health status alarms include lost connectivity, battery switchover and low system battery.
