Introduction

Not every endoscope camera module needs to be ultra-wide angle or high resolution.

In many real inspection devices, the user does not need to see the whole cavity. The user needs to focus on a small target area at a fixed close distance.

This is where the SF-U4530-SL-V3 becomes relevant.

It is a D4.5 integrated USB endoscope camera module using the BF2013 0.3MP sensor. It supports YUV / MJPEG output with 640×480 image output, includes 6 LEDs, uses a plastic lens, provides a 45° FOV and is designed around a 15mm focusing distance.

Its strongest value is not “high resolution.” Its value is focused close-range visual checking for OEM devices where the target distance is short, the viewing area is controlled, and the application needs practical live observation rather than wide-area navigation.

Why a 45° FOV Can Be Useful

Many buyers assume that a wider FOV is always better.

That is not true.

A 120° or 140° endoscope camera module can help users see more surrounding context, but the target may appear smaller in the image. This is useful for navigation, but not always ideal for focused inspection.

The SF-U4530-SL-V3 uses a 45° FOV.

This narrower viewing angle can be useful when the device needs to observe a specific target area, such as:

A small component

A connection point

A local surface area

A defined cavity feature

A fixed inspection position

A short-distance target

For projects where the user already knows where the target is, a focused view can be more useful than a very wide view.

Product Overview

The SF-U4530-SL-V3 is an integrated USB endoscope camera module.

Key specifications include:

D4.5 camera diameter

BF2013 sensor

0.3MP imaging class

ALL integrated type

USB output

YUV / MJPEG output

640×480 image output

6 LEDs

60mm front length

Plastic lens

45° FOV

15mm focusing distance

IP67: No

Dimming: No

Type-A connection

The catalog does not confirm standard cable length, maximum cable length, frame rate or main board size for this model. These details should be confirmed during project communication if they are important to the final product.

Customer Pain Point 1: “We Need to See a Specific Target Clearly, Not the Whole Space”

In many inspection tools, a very wide FOV is unnecessary.

The user may only need to check one area:

Is the component aligned?

Is the hole open?

Is the part damaged?

Is there visible contamination?

Is the surface condition acceptable?

For these tasks, a narrow FOV and close focusing distance may be more practical than an ultra-wide camera.

The SF-U4530-SL-V3 is suitable for this type of focused observation because it combines a 45° FOV with a 15mm focusing distance.

Customer Pain Point 2: “The Working Distance Is Fixed and Very Close”

Some endoscope applications do not require a broad focus range.

The device may be designed so the camera always stays close to the target.

In this case, a fixed 15mm focusing distance can be useful because the optical design is centered around one close-range viewing condition.

However, customers should not choose this model if the working distance varies greatly.

Before sample selection, confirm:

Is the target normally around 15mm from the camera?

Will the user move closer or farther during operation?

Does the device structure control the viewing distance?

Is the target flat, curved or reflective?

If the actual distance is much shorter or much longer, another module may be more suitable.

Customer Pain Point 3: “The Inspection Area Is Dark”

The module includes 6 LEDs to support local illumination.

This is useful for enclosed spaces where external light cannot reach the target.

However, the LEDs do not support dimming.

That means sample testing should include the real target surface. If the target is wet, metallic, glossy or strongly reflective, fixed LED brightness may create white spots or overexposure.

For stable close-range inspection, fixed LEDs may be acceptable. For highly variable lighting conditions, another model with dimming support may be better.

Customer Pain Point 4: “We Need Simple USB Output”

The SF-U4530-SL-V3 uses USB output and a Type-A connection.

This can be useful for simple OEM inspection devices, portable visual tools and systems designed around USB image input.

However, Type-A connection should not be treated as universal compatibility with every host.

OEM teams should test the module with the actual:

Host device

Operating system

Viewing software

Power supply

Cable routing

Device workflow

before confirming sample approval.

Customer Pain Point 5: “We Need an Integrated Front-End Structure”

This model is listed as an ALL integrated type.

For OEM projects, an integrated front-end camera module can be easier to evaluate mechanically than a separate camera head and remote board structure.

The 60mm front length is an important mechanical detail. Customers should confirm whether this length fits the probe, handle, tube, housing or insertion structure of the final device.

A compact diameter alone does not guarantee mechanical fit.

The full front length also matters.

Suitable Applications

The SF-U4530-SL-V3 can be evaluated for:

Focused close-range inspection tools

Equipment internal visual checking

Component position inspection

Small cavity observation

Portable USB inspection devices

Maintenance visualization tools

Appliance repair inspection

Automotive service inspection

OEM close-range visual checking devices

It is better suited for fixed-distance visual confirmation than broad navigation, high-detail imaging or waterproof inspection environments.

When This Module Is a Good Fit

Choose this model when your project needs:

D4.5 camera diameter

USB output

640×480 image output

6 built-in LEDs

45° focused FOV

15mm close focusing distance

Integrated camera structure

Type-A connection

Simple close-range visual inspection

Controlled target distance

It is especially suitable when the device is designed around a known close target position.

When Another Module May Be Better

Another model may be better if the project needs:

Wide-angle navigation

Higher resolution

Adjustable LED brightness

IP67 waterproof support

Working distance longer than 15mm

Flexible focus range

Medical high-detail visualization

AI inspection

Measurement-level defect analysis

A finished plug-and-play endoscope device

The correct selection depends on the task, not only the camera diameter.

Sample Testing Recommendations

After receiving samples, customers should test:

Image clarity at 15mm

Target size in the 45° FOV

LED brightness at the real working distance

Reflection on actual surfaces

Host compatibility

YUV / MJPEG output behavior

Mechanical fit of the 60mm front section

Type-A connection stability

Environmental protection needs

Real user operation workflow

The best sample test is not a general image preview.

It should answer one question:

Can the user clearly see the target that matters in the final device?

RFQ Checklist

Before requesting samples, provide:

Application scenario

Target object

Required camera diameter

Exact working distance

Target size

Need for focused or wide view

Lighting environment

Target surface material

Need for dimming

Waterproof requirement

Conclusion

The SF-U4530-SL-V3 is a compact D4.5 USB endoscope camera module for focused close-range inspection.

Its value is not high resolution or wide-angle navigation.

Its real value is the combination of D4.5 diameter, BF2013 0.3MP imaging, 640×480 output, 6 LEDs, 45° FOV, 15mm focusing distance and integrated USB device structure.

For OEM customers who need to inspect a known target at a fixed close distance, this model can be a practical imaging choice.
