SS&Si Dealer Network has begun distributing the Telecom Design AJV4 jamming alarm across North America. The device actively monitors cellular, 915 MHz, Wi-Fi, and Bluetooth frequency bands to detect unauthorized signal interference.
Why it matters
The deployment addresses the rising use of signal jammers by criminals to neutralize wireless security systems. The U.S. Department of Homeland Security recorded an 830% increase in signal-jammer seizures between 2021 and June 2025.
The AJV4 utilizes machine learning algorithms trained on 10 years of radio frequency data to identify jamming attempts. It establishes communication through noise using multiple network paths in under 30 seconds.
The players
SS&Si Dealer Network
A distribution entity that provides security hardware and alarm system components to integrators in North America.
Telecom Design
A Bordeaux-based manufacturer specializing in wireless hardware, alarm systems, and sensor-based monitoring technology.
The details
The AJV4 acts as a secondary security layer by connecting to monitoring centers independently of an existing alarm panel. It monitors cellular, Wi-Fi, Bluetooth, and 915 MHz frequency bands for anomalies consistent with jamming. Beyond radio frequency detection, the unit includes an LCD display, an SOS emergency button, and integrated sensors for air quality, humidity, and temperature.
Timeline
2021: Period marking the start of signal-jammer seizure growth data.
June 2025: Date of U.S. Department of Homeland Security seizure reports.
October 7, 2026: Announcement of the North American distribution agreement.
The Tech Race
The AJV4 serves as a technical counter-measure to the increasingly accessible tools used to bypass wireless security protocols. It follows a shift in the security industry toward hardened, multi-network fail-safes designed to maintain connectivity even when primary RF bands are compromised.
The AJV4 is currently available to security dealers and integrators throughout North America for inclusion in client security deployments. It functions as a standalone hardware addition that does not rely on a building's primary alarm panel to report threats.
The takeaway
The AJV4 represents a shift toward independent, radio-aware security monitoring in response to the growing prevalence of jamming hardware. Integrators and commercial security operators should monitor the efficacy of these machine learning-based detections against emerging, high-power jamming devices.
