The Portable Drainage Inspection Camera is a professional-grade video inspection system designed for visual assessment of drainage pipes, sewer lines, and confined pipeline environments.
Built around a 23 mm compact camera head, an 8-inch control unit, and a 50-meter push rod cable, this system provides reliable, repeatable inspection results for municipal services, plumbing contractors, industrial maintenance teams, and inspection professionals.
The system is engineered to support accurate condition assessment, fault identification, and documentation, helping technicians make informed maintenance and repair decisions based on real visual data rather than assumptions.
Main components and features
1). 23 mm Compact Camera Head – Designed for Confined Pipelines
The system uses a 23 mm diameter camera head, a proven size widely adopted in professional drainage and sewer inspection equipment. This diameter allows smooth entry into small and medium-diameter pipes, including branch lines and household drainage systems, while maintaining sufficient space for optics, lighting, and sealing.
Technical characteristics:
Camera diameter: 23 mm
Recommended pipe diameter: from approx. 25 mm and above
Viewing angle: wide-angle lens for comprehensive internal coverage
Illumination: integrated high-intensity LEDs for low-light environments
Waterproof rating: IP68 (suitable for fully submerged operation)
The camera housing is manufactured using corrosion-resistant materials to ensure long-term reliability in wastewater and damp conditions.
2). High-Visibility 8-Inch Control Unit
The inspection system is equipped with an 8-inch color display control unit, enabling operators to clearly observe internal pipe conditions in real time.
Display & Control Features
Real-time live video monitoring
Video recording and still image capture
Adjustable brightness and contrast for varying site conditions
Time and date overlay for inspection documentation
Simple, field-friendly interface suitable for gloves and outdoor use
The screen size strikes a balance between portability and visibility, allowing technicians to identify cracks, blockages, root intrusion, corrosion, joint displacement, and other common drainage issues directly on site.
3).50-Meter Push Rod Cable – Optimized for Practical Inspections
The system includes a 50-meter push cable, which is one of the most commonly specified lengths for professional drainage inspections in residential, commercial, and light municipal applications.
Cable Construction
Core material: fiberglass push rod
Outer jacket: abrasion-resistant protective layer
Balance of stiffness and flexibility: supports pushing through bends while maintaining directional control
This cable length allows sufficient reach for most drainage inspection tasks without compromising portability or handling efficiency.
Typical Inspection Applications
This Drainage Inspection Camera is suitable for a wide range of professional applications, including:
◆ Drainage and sewer line inspection
Used for routine inspection and fault identification in residential and commercial drainage systems.
◆ Plumbing maintenance and troubleshooting
Helps plumbers quickly locate blockages, cracks, or installation defects without unnecessary excavation.
◆ Municipal pipeline assessment
Supports inspection of lateral connections, small sewer branches, and maintenance verification.
◆ Property and facility management
Provides visual evidence for condition reporting, maintenance planning, and contractor coordination.
◆ Construction and renovation projects
Used for pre-handover inspections and post-installation verification of drainage lines.
Why Video Inspection Matters in Drainage Systems
Visual inspection using CCTV-based drainage cameras has become a standard method in modern pipeline maintenance.
Compared with guess-based diagnosis, camera inspection allows technicians to:
- Identify the exact location and nature of defects
- Reduce unnecessary digging or pipe replacement
- Improve repair planning accuracy
- Provide clear visual reports to clients or authorities
This system is designed to support those objectives with stable imaging and reliable operation.
Manufacturing & Quality Control Process
To ensure consistent performance and durability, each inspection system follows a structured production and inspection process:
1. Component Selection
Camera housings, lenses, cables, and connectors are selected based on corrosion resistance, mechanical strength, and long-term stability.
2. Camera Assembly & Sealing
Each camera head is precisely assembled and sealed to meet IP68 waterproof requirements.
3. Optical & Lighting Calibration
Lens alignment and LED illumination are tested to ensure uniform brightness and clear imaging.
4. Cable Stress Testing
Push cables undergo bending, pulling, and torsion tests to verify durability in real inspection conditions.
5. System Integration Testing
The complete system is tested for signal stability, recording functions, display performance, and connector reliability.
6. Final Inspection & Documentation
Each unit is inspected before shipment, ensuring functional consistency and traceability.
FAQ
Q1: What pipe diameters is this drainage inspection camera suitable for?
A: The 23mm camera head is designed for inspecting pipes with inner diameters from approximately 30mm to 150mm (1″–6″). It is well suited for residential, commercial, and light industrial drainage systems.
Q2: Is the camera head fully waterproof for sewer inspections?
A: Yes. The camera head is rated IP68, allowing it to operate safely in wet, submerged, and sewer environments commonly encountered during drainage inspections.
Q3: What is the maximum cable length available?
A: The standard configuration supports a push cable length of up to 50 meters (164 ft). If you require a longer cable, our other models push rod inspection cameras are more suitable.
Q4: Does the system support video recording and image capture?
A: Yes. The control unit can be equipped with DVR recording and SD card storage, allowing users to record inspection videos and capture still images for reporting and documentation.
Q5: Can the camera navigate bends and joints inside pipes?
A: The fiberglass push rod cable provides a balanced combination of rigidity and flexibility, enabling the camera to pass through standard pipe bends, elbows, and junctions commonly found in drainage systems.
Q6: Is a locating transmitter (sonde) available?
A: A 512Hz sonde transmitter can be integrated as an optional feature, allowing the camera head to be located from the surface using compatible pipe locators. Our this model 23mm portable drain camera supports 512Hz locator and slef leveling function.
Q7: Is this system suitable for professional and commercial use?
A: Yes. This drainage inspection camera is designed for professional plumbers, municipal maintenance teams, contractors, and inspection service providers requiring reliable and repeatable inspection results.
Q8: Do you support OEM or bulk orders for distributors?
A: Yes. We support OEM branding, bulk procurement, and distributor partnerships. Please contact us for MOQ, customization options, and commercial terms.
