Many endoscope camera projects are not limited by resolution. They are limited by viewing direction.
A standard single-lens endoscope camera can work well when the target is directly in front of the probe. But in real industrial inspection, pipe inspection, equipment maintenance and cavity observation, the target may appear on different sides of the inner wall.
The SF-SJT720 is a D7.9 USB endoscope camera module designed with a three-lens structure. It uses the OV9734 1MP sensor platform, supports YUV / MJPEG output, includes a 2+6pcs LED arrangement, provides 80°×3 FOV as listed in the catalog, and supports a 20–60mm focusing range.
Its main value is not simply “1MP.” Its real value is helping OEM customers build inspection tools that need multi-angle observation inside a compact space.
A single-lens camera sees one direction.
That is enough for many front-view inspection tools. But it may be inefficient when users need to inspect multiple surfaces inside a cavity.
A three-lens structure can help customers evaluate devices where the operator needs more viewing direction coverage without constantly repositioning the probe.
This can be useful for:
Pipe inner-wall observation
Cavity surface checking
Equipment internal inspection
Multi-direction maintenance tools
Industrial borescope devices
OEM inspection systems where side visibility matters
The customer should still confirm the exact optical layout and viewing direction before sample approval, but the three-lens design is the key reason this model should not be treated as a normal single-camera module.
The SF-SJT720 is an integrated USB endoscope camera module.
Key confirmed specifications include:
D7.9 camera diameter
OV9734 sensor
1MP imaging class
ALL integrated type
USB output
YUV / MJPEG output
2+6pcs LED arrangement
Plastic lens
80°×3 FOV listed in the catalog
20–60mm focusing range
IP67: No
Dimming: No
Type-A connection
Three-lens structure
The catalog does not clearly confirm output resolution, frame rate, standard cable length, maximum cable length, front length or main board size for this model. These details should be confirmed during project communication if they are important to the final device.
This is the strongest reason to evaluate SF-SJT720.
In pipe or cavity inspection, the operator may need to observe multiple directions. A single front-view camera can require more rotation, repositioning and repeated checking.
A three-lens module can help customers develop a device direction where multiple viewing areas are considered from the beginning.
For OEM projects, this may improve inspection workflow when the target is not always centered in front of the probe.
The model uses a 1MP OV9734 sensor platform.
This makes it more suitable for general visual observation than high-resolution documentation or measurement-level inspection.
It can be evaluated for tasks such as:
Wall condition checking
Blockage observation
Visible contamination
Internal structure checking
General surface condition review
Component position confirmation
For fine cracks, AI defect recognition or detailed measurement, another imaging platform may be more suitable.
The catalog lists a 2+6pcs LED arrangement.
For a three-lens module, lighting should not be evaluated only from one forward-facing view. Customers should test whether the lighting supports the actual viewing directions and target surfaces.
Key testing points include:
Brightness around each viewing area
Shadow between viewing directions
Reflection from inner walls
Light balance inside the cavity
Surface material response
Because dimming is marked as No, fixed brightness should be tested carefully before project approval.
The model lists a 20–60mm focusing range.
This makes it suitable for close-range visual inspection, but not every application will match this distance.
Customers should measure:
Closest expected target distance
Typical inspection distance
Maximum inspection distance
Distance from each lens direction to the target
Whether the operator can control probe position
If the actual target is normally closer than 20mm or farther than 60mm, another module may be better.
The catalog marks IP67 as No.
This is important.
SF-SJT720 should not be positioned as a waterproof endoscope probe. If the final application involves water, cleaning, oil, wet pipes or harsh moisture conditions, the customer should either design and validate a sealed final device or choose an IP67-supported model.
SF-SJT720 can be evaluated for:
Dry pipe inspection
Industrial cavity observation
Equipment maintenance tools
Multi-direction visual inspection
Machinery internal checking
Automotive service tools
Portable USB borescope devices
OEM three-lens inspection systems
It is best suited to dry or protected environments unless the final device includes its own validated sealing structure.
Choose SF-SJT720 when your project needs:
D7.9 camera diameter
Three-lens viewing structure
1MP-class image output
YUV / MJPEG USB output
80°×3 FOV direction
20–60mm working distance
Built-in LED arrangement
Type-A USB connection
Multi-angle visual inspection
No IP67 requirement at module level
Choose another model if the project needs:
Confirmed IP67 waterproof support
LED dimming
Higher resolution
Single-lens compact structure
Smaller diameter
Longer viewing distance
Known frame-rate requirement
AI or measurement-level inspection
Finished plug-and-play consumer device
Customers should test:
Actual viewing directions
Image clarity at 20–60mm
Lighting balance across lens directions
Reflection from the real inner wall
80°×3 viewing coverage
Host compatibility
YUV / MJPEG output behavior
Type-A connection
Mechanical fit of the D7.9 structure
Waterproof requirement at final device level
The sample should be tested inside the real cavity or a close simulation, not only on a flat desktop target.

SF-SJT720 is a D7.9 three-lens USB endoscope camera module for OEM customers who need multi-angle close-range visual inspection.
Its value is not only the OV9734 1MP sensor. The key value is the three-lens structure, 80°×3 viewing direction, LED arrangement and 20–60mm close-range observation for inspection devices where one viewing direction is not enough.
