3. Setup Guide
3.1 Android Device Setup
- Check OTG Support: Ensure your Android device supports OTG (On-The-Go) functionality. Most modern Android phones do, but you can verify this with an OTG checker app or your device's specifications.
- Download Application: Search for and download a compatible borescope or endoscope application from the Google Play Store. Recommended apps include "USB Camera", "OTG View", or "AN98".
- Connect the Borescope:
- If your phone has a Micro-USB port, connect the borescope's USB plug to the provided USB to Micro-USB adapter, then plug the adapter into your phone.
- If your phone has a USB-C port, you will need a separate USB-A to USB-C adapter (not included) to connect the borescope.
- Launch Application: Open the downloaded borescope application. The app should automatically detect the borescope and display the live video feed. Grant any necessary permissions (e.g., camera, storage).

3.2 PC Setup (Windows/Mac)
- Connect the Borescope: Plug the borescope's USB connector directly into an available USB port on your computer.
- Access Camera:
- Windows: Open the built-in "Camera" application or a third-party webcam software. You may need to select the borescope as the active camera.
- Mac: Open "Photo Booth" or "QuickTime Player" (File > New Movie Recording) and select the borescope as the camera source.
4. Operating Instructions
4.1 Basic Operation
- Power On: The borescope powers on automatically when connected to a compatible device and the application is launched.
- Adjust LED Brightness: The borescope features adjustable LED lights around the camera lens. Locate the brightness adjustment wheel or button on the USB connector or cable. Rotate/press to increase or decrease illumination for optimal viewing in dark environments.
- Navigate: Carefully insert the camera probe into the area you wish to inspect. Guide the flexible cable to maneuver the camera.
- View Live Feed: Observe the live video feed on your connected device's screen.
4.2 Capturing Images and Videos
Most borescope applications provide options to capture still images and record videos. Look for camera and video recorder icons within your chosen application's interface.
- Take Photo: Tap the camera icon to capture a still image of the current view.
- Record Video: Tap the video recorder icon to start recording. Tap again to stop.
- Access Files: Captured images and videos are typically saved to your device's gallery or a specific folder within the application.

5. Maintenance and Care
- Cleaning the Lens: After use, especially in dirty or wet environments, gently wipe the camera lens with a soft, lint-free cloth. For stubborn dirt, a small amount of lens cleaning solution can be applied to the cloth (not directly to the lens).
- Waterproof Care: While the camera head is waterproof, avoid submerging the USB connector or the main body of the cable in water. Ensure the camera head is clean and dry before storing.
- Cable Handling: Do not bend the cable sharply or apply excessive force, as this can damage internal wiring. Coil the cable loosely for storage.
- Storage: Store the borescope in its protective case in a cool, dry place, away from direct sunlight and extreme temperatures.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or strong chemicals on any part of the borescope.
