Standalone PIR Motion Sensor

The Amcrest SmartHome Standalone Alarm PIR Sensor adds wireless motion detection to a compatible alarm system. It is designed for indoor use in homes, sheds, offices or walkways. The sensor requires the Amcrest Alarm Hub, which is sold separately, to function.

Expands an Existing Amcrest Hub

This sensor upgrades a supported Amcrest Alarm Hub by adding a new detection zone. The system supports up to five sensors in total, so the jump is worth it when you need coverage for an additional room or entry point. Installation takes only a few minutes and the unit mounts on almost any surface.

Long-Range Wireless Detection

The sensor communicates with the hub at distances up to 100 metres (328 feet). Its passive infrared element detects movement up to 26 feet away across a 110-degree angle. This range is maintained during continuous operation rather than only in brief tests.

Questions about this item

What mounting options suit the sensor's 110° detection angle?

Mount the sensor on any flat surface so the 110° field covers the target area; the detection range extends to 26 feet indoors.

Which step do installers often miss when pairing the sensor with the Amcrest Alarm Hub?

The hub must be added first and placed within 100 m (328 feet) before the sensor will pair; skipping hub setup leaves the sensor unconnected.

When should the sensor's battery be replaced?

Replace the battery when the low-battery alert sounds or motion alerts stop arriving; the sensor is indoor-only, so temperature extremes do not accelerate drain.
