The EN1247 Glassbreak Sensor‑Transmitter has
patented GE ShatterPro II Pattern Recognition
Technology as well as the Inovonics EchoStream
platform. ShatterPro II provides a high immunity to
false alarms while covering several windows at once.
The Inovonics EchoStream platform uses diversity
reception and advanced signal processing to reduce
dead spots in transmission areas.

System overview

Powered by Inovonics

The Inovonics EchoStream platform, powered by
Inovonics wireless mesh network technology, ensures
superior range, reliability, and scalability for
commercial applications. Using a wide range of
transmitters and repeaters, this proven technology
provides flexibility and performance to meet the most
stringent requirements. This exclusive protocol is
available only on Inovonics EchoStream products.

Wireless 900 MHz Band

The Inovonics EchoStream platform sends redundant
information on several multi-frequency channels within
the FCC Part 15 900 MHz band, providing superior
range and reliability. In comparison, systems that use a
single frequency technology can only send information

u Recognizes the pattern of glass breaking across the

full audio band

u Low‑profile design

u Exclusive wireless protocol ensures maximum

performance and reliability

on one narrow band channel. Any interference within
the band can cause missed signals. With wireless
registration, it is easy to add this technology to any
application.
