| False alarms. | Sensor picking up unwanted movement (e.g., pets, swaying objects, sunlight changes). | Adjust sensor placement or angle. Ensure sensor is not facing direct sunlight or heat sources. |
| Short detection or wireless range. | Obstructions (thick walls, metal objects), electromagnetic interference, low transmitter batteries. | Relocate units to minimize obstructions. Avoid placing near large metal objects or strong electrical devices. Replace transmitter batteries. |
| Receiver constantly goes silent. | Internal malfunction or interference. | Try unplugging and replugging the receiver. If the issue persists, contact customer support. |
