Technical specifications for the eMACROS system identify a proprietary 433MHz radio frequency protocol designed for high-fidelity signal transmission. The hardware features an IP65-rated weather seal and utilizes a solar-charged 18650 lithium-ion cell for energy autonomy. Performance metrics demonstrate a trigger-to-chime response time of less than 100ms, providing near-instantaneous local alerts.
Engineering teardowns indicate that while signal propagation exceeds 1,500 feet under line-of-sight conditions, the plastic housing is subject to UV-induced yellowing over extended multi-year exposure. The system utilizes a passive infrared (PIR) element for detection. Monitoring capabilities include a chime-base unit with specific tuning for its audible alerts, though these tones lack high-fidelity digital sampling.
- Ingress Protection: IP65 Rated
- Power Source: Solar + 18650 Lithium-ion
- Transmission Range: 1,500ft+ LOS
Operational data suggests that mounting the sensor at a height of 3 to 5 feet and applying a downward angle minimizes false positives from thermal shifts and moving shadows. The absence of digital encryption allows for signal interception by similar 433MHz devices in high-density RF environments. The hardware architecture is optimized for rural or long-driveway applications where Wi-Fi stability is insufficient for reliable monitoring.
The eMACROS Solar Wireless Driveway Alarm - Long Range Motion Sensor is recommended for long-range rural perimeters where traditional 2.4GHz signals cannot maintain a stable link. This product is a specialized component of the driveway and yard alarms hardware class.
