- Automotive Maintenance: Examining engine components, spark plug holes, or other confined spaces in vehicles.
- Appliance Repair: Looking inside washing machines, refrigerators, or HVAC systems.
- General Home Inspection: Checking behind walls, under floors, or in tight crawl spaces.
- Retrieving Lost Items: Locating and potentially retrieving small items dropped in inaccessible areas.
7. Maintenance
- Cleaning the Lens: After use, especially in dirty or wet environments, gently wipe the camera lens with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying. Do not use abrasive cleaners or solvents.
- Cable Care: Avoid sharp bends or kinks in the cable, as this can damage internal wiring. Coil the cable loosely for storage.
- Storage: Store the endoscope in a cool, dry place, away from direct sunlight and extreme temperatures.
- Water Exposure: While the camera probe is IP67 waterproof, ensure the USB/Type-C connectors and the inline control unit remain dry. If they get wet, dry them thoroughly before connecting to any device.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No image on screen / Black screen | Incorrect app/software, loose connection, phone OTG not enabled, incompatible device. | Ensure the correct app is open and selected. Reconnect the endoscope firmly. Check phone settings for OTG function and enable it. Verify device compatibility. Try a different USB port or device. |
| Image is blurry or unclear | Lens is dirty, object is outside focal range, insufficient lighting. | Clean the camera lens. Adjust the distance to the object (optimal focal length is 4-10cm). Increase LED brightness using the inline control. |
| LED lights not working | Brightness dial set to minimum, power issue. | Rotate the brightness adjustment wheel on the inline control unit. Ensure the endoscope is properly connected and receiving power. |
| Device not recognized by computer | Driver issue, USB port problem. | Try a different USB port. Restart your computer. Check Device Manager (Windows) or System Information (macOS) to see if the device is listed. |
