QY6689D Dual Reel Sewer Camera Inspection System

System Configuration

13.3-Inch 1080P HD Screen

The QY6689D is equipped with a 13.3-inch 1080P high-definition screen, helping operators view pipe conditions more clearly during inspection. The larger display makes it easier to identify cracks, blockages, root intrusion, grease buildup, pipe deformation, joint separation and other internal pipe problems.

Dual Reel Compact Structure

The dual reel design integrates two inspection cable systems into one compact unit. Operators can choose the inner cable or outer cable according to pipe diameter, inspection distance and jobsite conditions. This design helps one system cover both medium pipe inspection and larger pipeline inspection tasks.

Inner Cable System

Cable Length: 30m / 98ft
Push Rod Diameter: 5.3mm
Camera Head: 21mm camera head
View Angle: 120° wide viewing angle
Suitable Pipe Diameter: 2"–5" / 50mm–125mm
Optional Functions: 512Hz sonde and self-leveling

The inner cable system is suitable for medium pipe inspection tasks. The 5.3mm push rod offers flexible handling, while the 21mm camera head provides a 120° wide viewing angle for sewer laterals, commercial drainage lines and residential pipe inspection.

Outer Cable System

Cable Length: 80m / 260ft
Push Rod Diameter: 7.2mm
Camera Head: 29mm camera head
View Angle: 150° ultra-wide viewing angle
Suitable Pipe Diameter: 3"–8" / 80mm–200mm
Optional Functions: 512Hz sonde and self-leveling

The outer cable system is designed for larger and longer pipe inspection tasks. The 7.2mm push rod provides stronger support for deeper inspection distances, while the 29mm camera head with 150° ultra-wide viewing angle helps operators capture more pipe wall information in large drainage and sewer pipelines.

Removable and Replaceable Camera Heads

The camera heads are removable, replaceable, detachable and field serviceable. This structure helps reduce downtime when inspection, repair or replacement is required. For professional sewer inspection contractors, field serviceability is important because it helps keep the equipment ready for frequent use.

Multi-Functional Camera Holders

The system is equipped with multi-functional camera holders for different pipe conditions. These holders help protect the camera heads, improve centering inside the pipe and support smoother camera movement during inspection.

Brake System and Turntable Design

The handy brake system and turntable design help operators control reel rotation during cable release and retrieval. This prevents the reel from spinning freely, reduces cable tangling and improves operation safety during sewer and drain inspection work.

Double Spinner Wheels

The QY6689D uses double spinner wheels with shock absorption, anti-slip and anti-corrosion design. This improves mobility when the system is moved between inspection areas, service vehicles, municipal worksites and commercial maintenance locations.

Level Telescopic Handle

The level telescopic handle supports double gear adjustment. The first gear extends approximately 25cm, and the second gear extends approximately 50cm. This makes the system easier to pull, transport and store during field operation.

Ergonomic Design

The system includes an automatic padlock, camera holders, plastic handle, spinner wheels and level telescopic handle. These ergonomic details help improve jobsite handling, reduce operating burden and support repeated professional inspection work.

Key Features

Two Camera Heads for Wider Pipe Coverage

The QY6689D combines a 21mm camera head and a 29mm camera head in one inspection system. The 21mm camera is suitable for medium sewer and drain pipes, while the 29mm camera is better for larger pipelines and longer inspection distances.

21mm Camera Head for 2"–5" Pipelines

The 21mm camera head works with a 30m 5.3mm push rod and provides a 120° wide viewing angle. It is suitable for 2"–5" / 50mm–125mm pipelines, including residential sewer laterals, commercial drainage lines and standard plumbing inspection tasks.

29mm Camera Head for 3"–8" Pipelines

The 29mm camera head works with an 80m 7.2mm push rod and provides a 150° ultra-wide viewing angle. It is suitable for 3"–8" / 80mm–200mm pipelines, making it useful for larger sewer lines, stormwater drains and municipal pipeline inspection.

80m Long-Distance Inspection Capability

The 80m outer push rod supports longer pipeline inspection distances compared with compact short-range systems. This makes the QY6689D suitable for deeper sewer lines, underground drainage routes and professional pipe survey projects.

Optional 512Hz Locating Function

The optional 512Hz sonde helps operators locate the camera head position from above ground when used with a compatible locator. This function is useful for identifying blockage points, pipe routes, repair locations and damaged pipe sections before excavation or repair.

Optional Self-Leveling Function

The optional self-leveling function helps keep the video image upright during inspection. This reduces confusion caused by camera rotation and makes pipe condition analysis easier for operators and customers.

13.3-Inch HD Display for Field Diagnosis

The 13.3-inch 1080P screen provides clearer viewing during pipe inspection. A larger display helps operators identify defects more efficiently and supports better communication with property owners, facility managers and maintenance teams.

Professional Dual Reel Cable Management

The dual reel structure allows operators to manage two different push rod systems in one compact unit. The brake system, turntable design, camera holders and telescopic handle help improve cable control, transport convenience and jobsite workflow.

Field Serviceable Camera Design

The detachable camera head structure supports easier replacement and maintenance. This is valuable for contractors who need to reduce downtime and keep inspection equipment available for daily sewer and drain service work.

Applications

Residential Sewer and Drain Inspection

The QY6689D can be used to inspect residential sewer laterals, basement drains, kitchen drainage lines, bathroom pipes and household plumbing systems. The 21mm camera head is suitable for many medium-sized residential pipe inspection tasks.

Commercial Drainage Maintenance

The system is suitable for hotels, office buildings, shopping malls, hospitals, schools, apartment buildings and other commercial facilities. The dual camera configuration helps maintenance teams inspect different pipe sizes with one equipment set.

Municipal Sewer Inspection

For municipal sewer and drainage maintenance, the 29mm camera head with 80m push rod is useful for larger pipelines, stormwater drains and underground sewer lines. Optional 512Hz locating can help teams identify problem positions more efficiently.

Long-Distance Pipeline Survey

The 80m outer cable system is suitable for longer inspection routes where compact short-cable cameras may not be sufficient. It supports pipeline condition assessment, route tracing, defect detection and maintenance planning.

Drain Cleaning and Blockage Diagnosis

Before or after drain cleaning, the QY6689D helps operators inspect blockage positions, grease buildup, sediment accumulation, foreign objects, pipe collapse and root intrusion. This supports more accurate cleaning and repair decisions.

Pipe Repair and Maintenance Service

Inspection service providers can use the QY6689D to document pipe defects, confirm repair points and provide visual evidence for customers. The 1080P display, dual camera heads and optional self-leveling function improve inspection efficiency and reporting clarity.
