In industrial inspection, whether examining gear wear inside a transmission, hidden faults in a gearbox, or probing the inner walls of long-distance pipelines, storage tanks, and confined spaces, a flexible, efficient, and reliable visual inspection tool is essential. Traditional solutions often require multiple dedicated devices: one borescope for small pipes, one push-rod camera for long pipelines, another for rotating scans… resulting in high costs, complex operations, and equipment clutter. A new all-in-one controllable endoscope system can simultaneously connect a 150-meter-long push-rod pipeline inspection camera and a 360° rotating electronic video endoscope probe, solving various inspection needs with a single system: using 4mm or 6mm micro probes for transmissions and gearboxes, and 17-50mm larger diameter probes for pipelines and tanks.
Regardless of the probe diameter, the performance of the camera module at the tip—the system’s “eye”—always determines image quality and diagnostic accuracy. A miniature, high-definition, wide-angle, waterproof, plug-and-play camera module is the core soul of this all-in-one system. The camera module’s diameter, resolution, field of view, waterproof rating, and system compatibility directly determine whether inspectors can see every crack, corrosion spot, and foreign object in narrow, dark spaces.
This system must satisfy two extreme scenarios:
Micro-channel inspection (gearboxes, transmissions, engine interiors): Probe diameters ≤6mm, camera must be very slim (ideally ≤4mm), yet provide clear images to identify tooth wear, burrs, and debris.
Long-distance pipeline inspection (water mains, oil/gas pipes, ventilation ducts): Probes can be up to 50mm, but need ultra-wide field of view to cover large pipe wall areas, plus waterproofing for wet environments and support for long-range signal transmission.
Thus, an ideal camera module should have:
Miniature diameter (≤4mm): Fits into 4mm and 6mm probes, accessing narrow openings.
HD real-time imaging (720P@30fps): Clearly shows metal fatigue cracks, weld defects, and deposit morphology.
Ultra-wide field of view: Covers more pipe wall at close range, improving efficiency.
IP67 waterproof: Withstands standing water, condensation, and rinsing fluids.
Plug-and-play & cross-platform: Direct connection to tablets or phones, supporting iOS for on-site viewing and recording.
Based on our understanding of industrial endoscopes and embedded vision, a Mini Camera Module truly suited for this system achieves precise alignment across diameter, imaging, FOV, protection, and interface.
When inspecting bearing housings or hydraulic valve bodies with inspection ports of only 6-10mm, standard borescopes often cannot enter. This 3.9mm Diameter camera module features a round steel sheath with an outer diameter of just 3.9mm, easily embedding into the tip of a 4mm or 6mm controllable probe. It reaches deep into gear meshing surfaces and clutch plate gaps, transmitting HD video in real time.
Fatigue cracks on gear teeth may be only 0.1mm wide; corrosion pits on pipe walls may be partially covered by deposits. Low-resolution cameras easily miss these critical defects.
This 720P Camera Module features the OV9734 CMOS sensor, outputting 720P (1280×720) HD resolution at 30fps (YUV/MJPEG). At typical working distances of 5-20mm, it clearly shows:
Fatigue cracks, pitting, and galling on gear teeth
Casting porosity and burrs on gearbox housing inner walls
Lack of fusion defects and corrosion pit depth on pipeline welds
Deposit types and accumulation thickness at tank bottoms
720P@30fps ensures smooth, blur-free video during manual push-pull or rotating scans, helping inspectors pinpoint faults accurately.
For long-distance pipeline inspection, inspectors want a single frame to cover as much pipe wall as possible, reducing probe movement. Standard 60-70° FOV borescopes require multiple scans, lowering efficiency.
This module features a 105° diagonal ultra-wide angle (distortion well controlled). Advantages:
At 10mm from the pipe wall, covers about 25-30mm laterally, showing more than half the circumference in one shot.
For 100-200mm diameter pipes, positioned centrally, it simultaneously shows the opposite wall and both sides, greatly reducing blind spots.
Combined with the system‘s 360° rotating probe, achieves full coverage without dead angles.
Whether standing water in drainage pipes or residual cleaning fluid in industrial tanks, the camera must function submerged. This module features an IP67 waterproof steel sheath, fully sealed, tolerating immersion at 1 meter for 30 minutes. The steel sheath provides compressive and bending strength, preventing deformation during long-distance pushing (up to 150 meters) despite friction and pressure. The smooth surface is easy to clean and disinfect.
Inspectors need rapid deployment, displaying the画面 on tablets or phones. This module uses a USB2.0 Type-C interface with built-in UVC driver-free protocol, natively supporting iOS systems (via Lightning or Type-C adapter). Advantages:
Plug-and-play: Connect to iPad, iPhone, or Android tablet without driver installation; open an app and view instantly.
Low latency: 720P@30fps real-time transmission keeps画面 synchronized with probe movement, no lag.
When paired with long-distance cables (up to 150 meters, using USB extenders or repeaters), the front-end image is transmitted losslessly to the control terminal.
1. Transmission and Gearbox Endoscopic Inspection: Use 4mm/6mm probes to enter gearbox bearing holes and oil passages, examining tooth wear, bearing cage cracks, and debris. 720P HD clearly resolves cracks as fine as 0.1mm.
2. Long-Distance Pipeline Internal Inspection: Select 17-50mm larger diameter probes with a 150-meter push-rod cable for water mains, heat networks, or gas lines. 105° ultra-wide angle covers large pipe wall areas quickly, locating blockages, corrosion, and leaks efficiently.
3. Tank and Confined Vessel Inspection: Insert the camera through manholes or process ports; use the 360° rotating probe to scan tank weld seams and floor corrosion. IP67 waterproofing handles residual liquids.
4. On-Site Rapid Recording and Report Generation: Connect to an iPad; inspectors mark defect locations on the screen, capture key images, and generate inspection reports on the spot, boosting productivity.
The core value of this integrated controllable endoscope system lies in “one machine for multiple tasks, replacing multiple dedicated devices.” Adding a 3.9mm diameter, 720P@30fps, 105° ultra-wide angle, IP67 waterproof, iOS-supporting miniature camera module enables the system to deliver clear, true, blind-spot-free visual information across a vast range of scenarios—from tiny gearboxes to long pipelines. Inspectors no longer need to carry multiple systems; just change the probe and handle any task.
