8. User Tips
- Optimal Viewing: Experiment with the LED brightness settings to find the best illumination for your specific inspection environment. Too bright can cause glare, while too dim will obscure details.
- Focal Distance: Remember the optimal focal length is 4-10cm. Try to keep the camera lens within this range from the object you are inspecting for the clearest image.
- Cable Management: While the cable is durable, avoid sharp bends or excessive force when maneuvering it to prolong its lifespan and maintain stable image transmission.
- Battery Life: For extended use, ensure the device is fully charged. If performing long inspections, consider having a portable power bank available for recharging.
- Lens Protection: Although the lens is IP67 waterproof, always clean it after use, especially after exposure to liquids or debris, to prevent residue buildup that could affect image quality.
