Powered by PowerG — the professional-grade wireless standard.
PowerG is a proprietary long-range, encrypted wireless technology developed by DSC (Johnson Controls) for commercial and law-enforcement installations. It's why Altium 360 ships PowerG on every eligible sensor instead of consumer-grade 319/345 MHz radios you'll find at big-box retailers.
Up to 2 km range
Line-of-sight from panel to sensor — one hub covers the whole property, even large lots and outbuildings.
128-bit AES encryption
Bank-grade encryption on every transmission. Virtually un-jammable and un-spoofable.
Two-way sync
Sensor and panel confirm every message. You'll know instantly if a device loses touch.
Up to 8-yr battery
Fewer service calls, lower total cost of ownership over the life of the system.
