It sounds like you're dealing with internal IR reflections—this is a known issue with the RLC-410WS, especially when installed near reflective surfaces like walls or eaves. These artifacts can definitely trigger false motion alerts at night. Make sure the lens is clean, angle the camera slightly away from flat surfaces, and try enabling 3D-NR to help reduce the false triggers. Also, consider using the Reolink mobile APK version for more precise control and real-time tweaks—it’s often more responsive than the web interface.
