Introduction
Many endoscope camera module samples fail not because the camera is poor, but because the wrong optical direction was selected.
A customer may ask for the highest resolution, the widest angle or the smallest diameter. But after testing, the real issue may be simpler:
The FOV does not match the inspection target.
The target is outside the focus range.
The fixed LEDs create reflection.
The host system is not tested.
The camera is used in an environment that requires waterproof support.
The SF-YL745-V2 is a D4.5 integrated USB endoscope camera module with GC1009 sensor, 1280×720@30fps output, 6 LEDs, 70° FOV and 30–80mm focusing range.
This article explains how customers should evaluate whether this model fits their inspection device before sample approval.
Start from What the User Needs to See
Experienced buyers do not choose a camera only by model number.
They start with the inspection task.
Ask:
What does the operator need to identify?
How large is the target?
How far is the target from the lens?
Does the user need a wide view or a focused view?
Is the surface reflective?
Is the environment dry or wet?
Does the host system support USB video input?
These questions help determine whether SF-YL745-V2 is the right direction.
Product Overview
The SF-YL745-V2 provides:
D4.5 camera diameter
GC1009 sensor
1MP imaging class
ALL integrated type
USB output
YUV / MJPEG format
1280×720@30fps
6pcs LEDs
Plastic lens
70° FOV
30–80mm focusing range
IP67: No
Dimming: No
Type-A / Type-C connection options
The model is best evaluated as a practical close-range imaging module, not as a waterproof or high-resolution inspection platform.
Customer Pain Point 1: "Should We Choose 70° or a Wider FOV?"
A wider FOV is useful when the user needs to navigate through a cavity or see more surrounding context.
But a wider FOV can also make the target appear smaller.
The SF-YL745-V2 uses a 70° FOV, which is more focused than many wide-angle endoscope modules.
This can be useful when the customer needs to observe a defined target area, such as:
A component
A hole
A blockage point
A local surface
A connector
A fixed internal structure
If the project needs broad navigation, a wider-FOV module may be better. If the project needs local inspection, 70° may be a more suitable choice.
Customer Pain Point 2: "The Target Must Be Clear at the Real Working Distance"
The focusing range is 30–80mm.
This means the module is better suited to applications where the target is not extremely close to the lens and not too far away.
Customers should not select the module only because it is D4.5 and 1MP.
They should first confirm:
Is the target normally within 30–80mm?
Does the distance stay stable?
Does the user move the camera closer or farther?
Is the target flat or curved?
Is the target large enough in the 70° frame?
If the distance does not match, another optical configuration may be more suitable.
Customer Pain Point 3: "The LEDs Help, but Can They Cause Reflection?"
The module includes 6 LEDs.
This is useful for dark cavities, but the catalog marks dimming as No.
Fixed LED brightness may work well when the working distance is stable and the target surface is not strongly reflective.
It may create problems when inspecting:
Wet surfaces
Polished metal
Glossy plastic
Curved reflective parts
Bright internal walls
Customers should test the real target material before confirming the model.
Customer Pain Point 4: "Is 1MP Enough?"
For many basic inspection tasks, 1MP can be enough.
It can support clearer observation than VGA-level modules when the user needs to see general structure, visible blockage, component position or obvious surface condition.
However, 1MP may not be enough for:
Fine crack detection
Precision measurement
Tiny defect classification
AI recognition
High-resolution documentation
Detailed medical imaging
The decision should be based on the smallest target feature that must be seen.
Customer Pain Point 5: "Can We Use It in Wet Environments?"
The catalog marks IP67 as No.
Customers should not position this model as a waterproof probe.
If the application involves liquid, cleaning, oil, wet pipes or high humidity, customers should either design a validated sealed structure or choose another module with confirmed IP67 support.
This should be clarified early to avoid sample mismatch.
Customer Pain Point 6: "Type-A or Type-C Does Not Automatically Mean Universal Compatibility"
The module offers Type-A / Type-C connection options.
This gives customers flexibility, but host compatibility still depends on the complete system.
Customers should test:
Host hardware
Operating system
USB support
Viewer software
Power supply
Cable routing
Product workflow
Do not assume that a Type-C version can connect directly to every phone or tablet without system verification.
Best-Fit Applications
This module can be evaluated for:
Basic industrial inspection
Equipment internal observation
Component position checking
Dry cavity inspection
Maintenance visualization tools
Automotive service inspection
Appliance repair tools
Portable USB visual inspection devices
OEM device-integrated viewing tools
It is especially useful when the customer needs a defined local view at 30–80mm rather than ultra-wide exploration.
Less Suitable Applications
Another module should be considered for:
Wet inspection environments
Very close focus below 30mm
Long-distance observation beyond 80mm
Ultra-wide navigation
High-resolution documentation
AI or measurement-level inspection
LED brightness adjustment
Harsh industrial waterproof use
Advanced medical visualization
Sample Evaluation Checklist
Before approving the sample, test:
Image clarity at 30mm, typical distance and 80mm
Target size in the 70° FOV
Whether 1MP shows enough detail
LED brightness
Surface reflection
Host compatibility
YUV / MJPEG output behavior
Type-A or Type-C connection stability
Mechanical fit
Waterproof or sealing requirement
This test should focus on the final user's inspection decision, not only whether the image looks acceptable on a screen.
RFQ Checklist
Before requesting samples, provide:
Application
Target object
Smallest feature that must be visible
Camera-to-target distance
Required FOV
Need for wide navigation or local inspection
Surface material
Lighting environment
Need for LED dimming
Waterproof requirement
Host device
Type-A or Type-C preference
Sample quantity
Estimated production volume
Mechanical constraints
Conclusion
The SF-YL745-V2 is a practical 1MP USB endoscope camera module for customers who need local close-range inspection at 30–80mm.
Its strongest value is not extreme resolution or ultra-wide viewing. It is the balance of D4.5 structure, 1280×720@30fps output, 6 LEDs, 70° focused FOV and USB integration.
For the right application, this model can offer a clearer and more practical option than VGA modules without pushing the customer into unnecessary high-end specifications.
