2. Safety Information
- This product is designed for indoor use only. Do not expose to water or high humidity.
- Ensure the power adapter is connected to a suitable 12V DC power source.
- Do not attempt to repair or modify the product. Contact support if issues arise.
- Keep out of reach of small children. While the strip operates at low voltage and produces minimal heat, proper placement is advised.
- Unplug the power adapter before installation, cleaning, or when not in use for extended periods.
3. Setup and Installation
Follow these steps for proper installation of your HOUHUI Dual Motion Sensor LED Strip Lights:
- Prepare the Surface: Ensure the installation surface is clean, dry, and smooth. Wipe the area with a clean cloth to remove dust or debris. For optimal adhesion, you may use rubbing alcohol to clean the surface and allow it to dry completely.
- Plan the Layout: Determine the desired path for the LED strip. The strip is flexible and can be routed around corners. Consider the placement of the two motion sensors to cover the intended detection areas (e.g., both sides of a bed, top and bottom of stairs).
- Cut the Strip (Optional): The LED strip can be cut to your desired length at designated cutting marks (usually indicated by a copper pad and a scissor icon). If cutting, ensure the power is disconnected. Use the included 3-PIN connecting cables to rejoin cut sections if needed.
- Attach the Strip: Peel off the backing from the self-adhesive tape on the back of the LED strip. Carefully press the strip onto the prepared surface, applying firm pressure along its entire length to ensure good adhesion.
- Connect Power: Connect the 12V power adapter to the LED strip. Ensure a secure connection. Plug the power adapter into a standard electrical outlet.

4. Operating Instructions
The HOUHUI Dual Motion Sensor LED Strip Lights are designed for automatic operation:
- Motion Activation: The LED strip will automatically illuminate when motion is detected by either of the two integrated sensors. The sensors have a detection range of approximately 10 feet (3 meters) and a 120-degree field of view.
- Dual Sensor Functionality: With a motion sensor at each end of the strip, the system can detect movement from two different directions. This is ideal for areas with multiple entry points, such as under a double bed or along a staircase.
- Automatic Shut-off: After motion ceases, the lights will remain on for approximately 60 seconds before automatically turning off to conserve energy.
- Continuous Operation: If motion is continuously detected within the sensor's range, the lights will remain on.

5. Maintenance and Care
To ensure the longevity and optimal performance of your LED strip lights, follow these simple maintenance guidelines:
- Cleaning: Gently wipe the LED strip and motion sensors with a soft, dry cloth to remove dust. Do not use liquid cleaners or abrasive materials.
- Environment: As the product is non-waterproof, avoid installing it in areas prone to moisture or direct water exposure. Maintain a dry indoor environment.
- Power Connection: Periodically check the power adapter and connections for any signs of damage or loose fittings.
- Heat: The LED strip operates at a low voltage (12V) and generates minimal heat, making it safe to touch. Ensure proper ventilation around the power adapter.
