Quick Answer
A multi-camera endoscope is only useful if each viewing direction can actually see the target.
The SF-SPA65-3A34 combines one forward camera, two side cameras and distributed white LED illumination, providing a three-direction inspection option for dark confined spaces.

Why Illumination Must Match the Viewing Direction
Inside a pipe, cavity or machine interior, ambient light is usually limited. Adding more camera directions does not automatically improve inspection if the side cameras cannot illuminate the surfaces they need to see.
This is why the lighting layout should follow the optical layout. The SF-SPA65-3A34 places stronger illumination around the forward camera and dedicated white LEDs with the side cameras, helping each viewing direction receive local light.

Key Advantages of the SF-SPA65-3A34
Forward and Two Side Views
The three-camera structure supports inspection of the area ahead of the probe and two side directions. It is useful when the operator needs broader directional awareness without repeatedly rotating the camera head.
Lighting Distributed by Viewing Direction
The forward camera integrates eight white SMD LEDs, while each side camera has its own white LED. This design helps place illumination closer to the actual viewing direction rather than relying on one light source for every angle.
Different Focus Positions for Different Views
The forward and side cameras are designed around different close-range focus positions. This can be useful because the front target and side wall are not always located at the same distance from the camera head.
7.9 mm Integrated Protected Head
The integrated metal-sleeve structure supports IP67 protection, providing a practical direction for endoscope equipment used in dusty, damp or confined inspection areas.
Typical Applications
Pipe Wall Inspection
Useful when the front area and multiple side-wall regions need local illumination during the same inspection.
Mechanical Cavity Inspection
Helps inspect internal components or surfaces that appear at different directions around the probe.
Industrial Borescope Equipment
Suitable for inspection tools that need multi-direction viewing and integrated lighting in a compact head.
When Should You Consider This Camera Module?
Consider this model when your inspection path requires three viewing directions and side-view illumination is as important as the number of cameras.
FAQ
Why does each side camera need its own LED?
A side camera looks in a different direction from the forward camera. Dedicated local illumination can help light the side wall that the side lens is actually viewing.
Is more LED always better?
No. LED quantity should match the working distance, reflective surfaces and camera direction. Too much close-range light can also create glare or reflection.
Why can the camera views use different focus distances?
The forward target and side wall can be at different physical distances from the lens. Different focus settings allow each view to better match its inspection area.
What information is needed for selection?
Provide the access diameter, viewing directions, working distance for each view, target surface, lighting requirement and USB host information.
