5.5mm BF20A6 Sensor Integrated USB Endoscope Camera Module For Drain Inspection
Guangzhou Sincere Information Technology Ltd. is one of the most professional 5.5mm bf20a6 sensor integrated usb endoscope camera module for drain inspection manufacturers and suppliers in China. Welcome to wholesale discount products for sale here from our factory. Customized orders are welcome.
A blocked drain entrance, a concealed clip or an object behind a panel can be difficult to assess without bringing a camera close to it. This module combines imaging, processing and local illumination in a compact assembly, providing equipment manufacturers with an integrated camera option for small inspection probes.
The lens is designed for observation within 20–60mm, with a 72° diagonal view for examining the area ahead of the probe. Its 640 × 480 video at 30fps supports visual checks of object presence, position and visible condition.
The Steel Shell protects the camera head, while built-in LEDs illuminate areas that external lighting cannot easily reach. When brightness adjustment is needed, the optional dimming module allows users to change the illumination by turning a hardware wheel.
Features

• Integrated Camera Design for Compact Probes
The imaging and processing sections are combined within the module, reducing the need to accommodate a separate DSP board elsewhere in the inspection device. This structure supports compact probe assemblies with USB 2.0 output.
• 5.5mm Camera Head with Steel Shell and IP67 Protection
The 5.5mm camera head combines a small diameter with Steel Shell and IP67 dust and water protection. It provides a protected viewing head for inspection tools used around dusty equipment gaps or damp drain openings.
• 6 Built-In LEDs with Optional Wheel-Controlled Dimming
6 LEDs bring illumination directly to the observation area. An optional hardware dimming module lets users adjust brightness with a wheel as the viewing distance or surface reflectivity changes.
• Close-Up VGA Viewing at 30fps
The BF20A6 CMOS sensor delivers 640 × 480 video at 30fps. Combined with a 72° lens and a 20–60mm working range, it supports close-up checks of obstructions, debris, component positions and other visible conditions.
• Optional 4.5mm Bare Module
A 4.5mm Bare Module is available for products that provide their own Shell and require a smaller camera assembly. The Bare Module does not carry the IP67 protection of the 5.5mm Steel Shell version.
Application of Endoscope Camera Module
• Drain Entrance and Short Pipe Inspection
The camera can support tools used to locate hair buildup, residual material and visible obstructions near drain entrances or within accessible short pipe sections. Built-in illumination brings light to the target, while the protected camera head supports inspection around damp areas.
• Air-Conditioning Drain Pan and Outlet Checks
Condensate drain outlets and nearby equipment gaps can be difficult to view directly. A small camera probe can help users examine accessible areas for debris, accumulated dirt or visible blockage. The optional brightness control allows illumination to be adjusted as the camera moves between dark recesses and nearby reflective surfaces.
• Behind-Panel Automotive Inspection
The module can provide a viewpoint behind dashboard trim and interior panels to check visible cable routing, clip positions or dropped objects. Its integrated construction suits small probe assemblies, while close-up viewing helps users locate the area that needs attention before deciding how to access it.

Customization Options
Steel Shell or Bare Module
Choose the 5.5mm version with Steel Shell for a protected camera head, or discuss the 4.5mm Bare Module when the finished product provides its own Shell. This allows the camera configuration to be matched to the available probe space and protection requirements.
Optional Wheel-Controlled Dimming Module
The camera includes 6 LEDs. Add the optional dimming module when users need to adjust brightness during inspection. The wheel position and its arrangement within the finished device can be reviewed around the intended operating method.
Cable and Connector Arrangement
Cable length, connector requirements and cable routing can be discussed to suit the probe, handle and viewing-device layout. These choices help coordinate the camera assembly with the physical arrangement of the finished tool.
Lens and Working-Distance Matching
The standard configuration provides a 72° diagonal view and a 20–60mm working range. Different viewing-angle or working-distance requirements can be reviewed to determine suitable optical options.
Probe and Shell Fit
Requirements for fitting the camera into a probe or the product's own Shell can be discussed during configuration selection. The review can cover available space, cable exit direction and the protection needed for the intended use.

FAQ
Q: How Can I Tell Whether VGA Resolution Is Enough for My Inspection?
A: Evaluate a sample using the actual object and viewing distance. Check whether the image shows the obstruction, component position or surface condition you need to assess. The size and contrast of the target matter alongside the camera's resolution.
Q: What Should I Order to Evaluate Adjustable Lighting?
A: Specify the optional wheel-controlled dimming module with the camera sample. The 6 LEDs are part of the camera configuration; adjustable brightness requires the additional dimming module.
Q: Does the Camera Include a Display or Recording Function?
A: This product is a camera module with USB 2.0 output. Viewing requires a compatible host and application. Recording and image capture depend on that viewing setup, so they should be checked as part of sample evaluation.
Q: Can IP67 Protection Be Treated as Approval for Cleaning Chemicals?
A: No. The camera-head IP67 rating does not establish compatibility with detergents, solvents or other cleaning chemicals. Discuss the intended cleaning method when selecting the assembly, including protection for the cable connections and the rest of the device.
Q: Can I Compare Both Diameters Before Choosing a Configuration?
A: Discuss samples of the 5.5mm Steel Shell version and the 4.5mm Bare Module. Comparing their fit in your probe design can help determine whether the protected camera head or the smaller bare assembly better suits the product.
