The Main Controller

The main controller is a computer system that monitors and processes incoming signals from the other components. The computer is a solid state (fanless) computer that runs our proprietary M900 software in order to configure and control all the other SECURalert ™ components. The main controller works on a system of bidirectional communication, meaning that when another component sends a signal to the controller, the controller sends an acknowledgement back, providing incomparable reliability for the system.

The Radio

The SECURalert ™ radio device converts radio waves to ethernet signals. Every system requires at least one radio device, but for larger facilities, we recommend installing a radio every 30 meters when used indoors.

The Receiver

The receiver is a small, ultrasonic device mounted on the wall of each room. If someone presses a panic button in that room, that receiver will alert the main controller. We offer several models of receivers, including the popular battery-powered receivers that can be installed in minutes without needing to rewire the building. Batteries last an average of 5 years, and each receiver monitors its own battery status, and sends a low battery notification to the main controller.

The Transmitter

The transmitter is a small portable device that can be worn on someone’s wrist, belt or lanyard. Some models contain a test button allowing the user to verify at any time that the device is working. The transmitters are rechargeable and will run up to 4 weeks on a single charge. Battery operated transmitters are also available and can last up to 16 months.


SECURalert ™ is proud to have incorporated many innovations into our system. One of the most important features of our technology is that it does not run on your building’s wifi. This means that panic button transmissions will get through normally, even during peak wifi usage times. In addition, installing our product doesn’t require expensive servers for the backend.

YES! I Need Panic Alert Buttons.
Radio Frequency (RF)

Radio Frequency (RF) waves will penetrate walls, ceilings, floors and glass and therefore require a triangulation calculation to compute a location of the panic button location. The more radios used will help improve the accuracy. The RF application is perfect for outdoor areas such as courtyards, parking lots or for less critical indoor areas where exact room location is not required.


Since the behavior of ultrasonic waves prevents them from penetrating ceilings, wall, floors or glass, this technology is excellent for pinpointing the exact room when a panic button is pressed. The ultrasonic waves bounce off hard surfaces until they are reached by the in-room ultrasonic receiver within milliseconds. Ultrasonic technology is not suitable for outdoor applications.


The SECURalert ™ Hybrid solution combines ultrasonic and RF technologies to provide users with optimum reliability and accuracy in any environment. The Hybrid transmitter emits both signals simultaneously with the ultrasonic being the primary signal while the RF acts as a redundant technology to ensure that no signal ever gets lost and a location is always delivered. It is 2 systems in one!

Inovonics – Additional Hardware

SECURalert’s ™ core operating unit and XTendCall’s™ Integration & Mobile platform also works with legacy hardware and EchoStream Commercial Mesh Network from Inovonics. Several facilities use Inovonics wireless sensor networks for commercial and safety applications.

Our technology is second to none, but it will only help you if you get it installed before a crisis occurs. Contact us today to get started.
