Hardwired & Wireless Burglar Alarm Systems

Ten years ago, “wireless commercial alarm” meant a compromise. That’s no longer true. Modern encrypted, supervised wireless — particularly PowerG-based systems — performs reliably enough that the choice comes down to your building and your budget.

PowerG — found in DSC and Qolsys systems — uses frequency hopping to avoid interference, adaptive transmission power, and encrypted two-way communication with full device supervision.

Practically, this means we can now propose wireless for buildings where we’d have insisted on hardwiring a decade ago, and the customer saves real money on labor without accepting a weaker system.

We hardwire the panel, keypads, sirens, and perimeter openings, then go wireless for interior devices and anywhere a cable pull costs more than it’s worth.

A typical retrofit: hardwired contacts on the front door, back door, and overhead dock door; hardwired keypads at both entrances; wireless motions throughout the interior; wireless glassbreaks in the showroom; wireless water sensor in the server closet.
