Technical specifications for the Htzsafe T791 list a transmission range of 0.5 miles under line-of-sight conditions. The hardware utilizes an IP66-rated industrial housing, providing a higher level of ingress protection than standard consumer variants. Signal propagation is achieved through 433MHz Frequency Shift Keying (FSK), which performance data shows to be effective at penetrating exterior masonry and metal siding.
Industrial Build and Scalability
Structural analysis highlights the use of a high-gain antenna on the receiver unit to facilitate long-range connectivity. The sensor array is powered by AA batteries, facilitating field serviceability without the need for proprietary power packs. Monitoring capabilities include support for up to 32 sensors across four distinct zones, with each zone capable of triggering a unique chime tone for identification.
Performance metrics indicate that the system is susceptible to RF shadowing if placed in close proximity to high-powered mesh Wi-Fi nodes, requiring a minimum 3-foot clearance. Technical documentation confirms that while the system excels in raw range, it does not include a native application for remote notifications. Operational data indicates that cold climates may significantly reduce the service life of alkaline batteries, suggesting the use of lithium alternatives for consistent winter performance.
When the installation site involves significant distances or physical obstructions, the Wireless Driveway Alarm with Long Range Sensor is recommended for its high-gain antenna and industrial-grade IP66 housing. This device is an advanced iteration of standard driveway and yard alarms.
