Wireless intrusion systems are sometimes shied away from as ideal commercial solutions due to the perception of them being complicated systems that require time-consuming installs, with potential for strong interference and increased on-site maintenance. However, there is wireless intrusion technology that has turned the security industry on its head in numerous parts of the world and is finally gaining momentum in North America.
There are several industry innovations that set PowerG wireless technology apart from other wireless possibilities. One of those distinctions is frequency hopping. Here’s how it works: the intrusion device, such as a motion detector, hops around channels within the specified frequency at a constant pace to find the clearest channel. It takes a large frequency band, such as the 912-918 Mhz band, and divides that into 50 channels, translating into less interference and increased robustness of communication. Frequency hopping enables for coverage of larger areas with fewer repeaters, extended ranges, stronger communication, and better signals.
Adaptive best path transmission power means that the intelligent intrusion devices continuously find easy, strong routes of communication to the panel. That means that PowerG’s high transmission ranges offer reliable communication within / up to 2km / 2187 yards line-of-sight and that systems can reliably send images and audio clips wirelessly.
Constantly hopping frequencies to find the best signal makes devices more efficient and cuts down on interference caused by other equipment or machinery. It also increases security, making it nearly impossible for listening devices to hack into a system. Coupled with 128-bit encryption, one of the most secure web-based encryption standards in place today, provides the highest level of protection against analysis tools and digital attacks.
PowerG technology employs the same, proven frequency technology that is used by Bluetooth and is part of 4G, the fourth generation of mobile telecommunications technology used in mobile devices today. Thanks to this approach, data interception is extremely difficult to achieve.
Another benefit of this technology is two-way synchronous TDMA communication. Two-way devices allow for back and forth communication – ensuring alarm signals aren’t missed and reducing information collisions. TDMA communication allows each device to talk and understand each other without talking at the same time–particularly useful for applications with a significant number of devices. Ordered time slots for each device minimizes collisions between signals and allow for more devices in an application. Full two-way communication also allows devices to receive orders back from a panel.
In addition, because of the efficiency of adaptive path technology and frequency hopping, the battery savings with such technology is significant. The intelligent intrusion devices find the easiest and closest way to speak with the panel therefore battery power isn’t wasted on inefficient paths of communication or signals that go nowhere. This way battery life ranges increase from five to eight years, depending on the device.
With significantly improved security and reliability, less interference and battery savings, wireless intrusion systems with PowerG technology make going wireless an ideal solution for a wide range of applications. Learn how PowerG is used in PowerSeries Neo from DSC.
