New York licensing proposal draws criticism; concerns over fire protection districts getting into the monitoring business


The PowerG network uses Two-Way Low-Power Frequency Hopping Spread Spectrum (FHSS) technology-similar to military communication systems. The network hops between multiple frequencies spread over the entire assigned frequency band, ensuring transmissions arrive uninterrupted. Frequency hopping is achieved using a unique encrypted pseudo-random sequence known only to the devices enrolled in the alarm panel.

Similar to the GSM cellular network, PowerG employs full two-way synchronized Time Division Multiple Access (TDMA) communication technology: each device in the PowerG network is allocated unique timeslots for full two-way data transmission with the panel, streamlining communication and increasing channel efficiency.

PowerG employs advanced radio and diversity antenna technologies that, when combined with FHSS and synchronized TDMA communication, result in a transmission range of over 2000m (6,000 ft.) line of sight and uses AES encryption.

Reed Sensors: Old Dog with New Tricks and More Security!

Founders of Magnasphere(r) Corp., Waukesha, Wis., have taken decades-old Reed switch detection technology for security contacts to new heights. Originally developed by Bell Labs in the late 1930s, Reed switches had three weaknesses: easy potential defeat with magnets; permanent contact weld failure from lightening and power surges; and fragile glass construction. Concealed and surface-mount sensors with Magnasphere's magnet ball contact technology are resistant to these weaknesses, making it a higher security application product.
