Material analysis of the SimpliSafe Motion Sensor (Gen 2) confirms the use of a Fresnel lens array designed to isolate heat signatures at human height. This physical lens masking is calibrated to filter thermal masses equivalent to pets under 50 lbs when the unit is installed at a vertical clearance of 6.5 feet. The device operates on a sub-GHz encrypted frequency to facilitate wall penetration in large-scale residential structures.
Technical specifications indicate a power requirement of one CR123A lithium cell, which supports an operational duration of 3 to 5 years. The internal electronics are configured for a closed-loop proprietary RF protocol, restricting interoperability with open standards such as Matter or Thread. Performance metrics indicate that rapid temperature fluctuations near HVAC vents can trigger the PIR element, resulting in non-verified alert states.
Monitoring capabilities for this unit include:
- Sensing: Single-purpose passive infrared detection.
- Environment: Optimized for indoor climate-controlled spaces.
- Protocol: Sub-GHz secure transmission.
Aggregated data suggests the absence of auxiliary environmental sensors, such as light or temperature modules, which are frequently found in multi-purpose alternatives. System integration is limited to the proprietary manufacturer hub for all automation and professional monitoring functions.
Those seeking a dedicated PIR solution with integrated pet-shielding logic may utilize the SimpliSafe Motion Sensor as a primary detection node. This device is positioned within the motion and presence sensor hardware class, specifically for high-security internal environments.
