Technical specifications confirm the Dakota Alert system utilizes the Multi-Use Radio Service (MURS) band, operating within the 151.820 MHz to 154.600 MHz frequency range. Aggregated data indicates that the 2-watt output capacity of this VHF hardware allows for signal propagation across a verified 2-to-4 mile line-of-sight distance. Material analysis of the sensor housing identifies heavy-duty ABS construction integrated with silicone gaskets to provide environmental resistance.
Signal Architecture and Modulation
Performance metrics demonstrate that the system employs Frequency Modulation (FM), which establishes a higher threshold of immunity against electromagnetic interference compared to standard AM-based consumer units. Monitoring capabilities include compatibility with handheld VHF transceivers, as the analog signal is transmitted on open MURS channels without digital encryption. Structural configurations for the Passive Infrared (PIR) sensors require a 6-month maintenance cycle for battery replacement in high-traffic deployments.
Standardized testing protocols show that the sub-GHz frequency utilized by this unit maintains signal integrity through dense foliage and structural barriers that typically attenuate 2.4GHz or 433MHz signals.
The hardware interface is designed for offline operation, ensuring that monitoring remains functional during network outages. System expansion is supported for an unlimited number of MURS-compatible receivers. Technical documentation confirms the inclusion of a relay output on the base station, which allows for mechanical bridging to secondary notification hardware.
Those requiring a similarly robust wireless infrastructure might consider the Dakota Alert Long Range Wireless Driveway Alarm System for its specialized high-wattage VHF transmitter array. This hardware is classified within the broader ecosystem of driveway and yard alarms, which serve as foundational components for perimeter access monitoring.
