The QY6688-13.3inch-21mm-5.3mm pipe inspection system is a cutting-edge solution designed for precise diagnostics in sewer, drain, and plumbing systems. Equipped with a 13.3-inch high-definition LED screen (1920*1080 resolution) and a 21mm camera head with 1080P resolution, it delivers crystal-clear visuals even in low-light environments, thanks to 12 high-light LEDs and 8x zoom. Its standout features include a self-leveling function and optional 512Hz transmitter, ensuring stable, accurate imaging during inspections. The system’s 5.3mm fiberglass cable (available in 10M-50M lengths) offers flexibility for navigating pipes 2” to 6” (50mm-150mm) in diameter, while the detachable camera head simplifies field maintenance. Built for durability, the camera housing uses 304# stainless steel with an IP68 waterproof rating (resistant to 3bar pressure, ~30 meters depth), making it ideal for harsh industrial and municipal environments.

The 1080P resolution (1920*1080) of both the screen and camera ensures sharp, detailed visuals of pipe interiors—critical for identifying cracks, blockages, or corrosion. The 12 high-light LEDs eliminate shadows in dark pipes, while 8x zoom magnifies small defects, such as biofilm growth or minor leaks, that might otherwise go unnoticed.
The 5.3mm fiberglass cable balances flexibility and strength, navigating bends in pipes without kinking. Its 10M-50M length options suit projects ranging from residential plumbing to large-scale municipal sewer inspections. The 304# stainless steel camera housing and sapphire front lens resist corrosion and scratches, even in acidic (pH 1-14) or slurry-filled environments.
A wireless PC keyboard simplifies control, while the self-leveling camera head automatically adjusts to keep footage upright—reducing operator fatigue during long inspections. The system supports meter/feet unit switching, and its 9000mAh battery provides 5-6 hours of runtime, with a car charger option for extended use.
Built-in DVR functionality records audio, video, and photos, stored on SD/USB drives (up to 1TB). This streamlines reporting for engineers, contractors, or municipal teams, ensuring easy tracking of pipe conditions over time.
Ideal for inspecting municipal sewers, residential drains, and stormwater pipes, the system identifies blockages, root intrusions, or structural damage—helping prioritize repairs and prevent overflows.
Used in commercial buildings, factories, and hospitals to check water mains, HVAC ducts, and milk pipes. Its compact 21mm camera head navigates narrow plumbing lines, detecting leaks or scale buildup.
Valuable for inspecting offshore risers, geothermal well casings, and fuel hydrant systems (e.g., airport runways). The IP68 rating and corrosion resistance ensure reliability in harsh, high-pressure environments.
Equipped with an optional UV module, it detects illegal pollutant discharges in municipal sewers—supporting environmental agencies in enforcing regulations.
The large 13.3-inch 1080P screen provides clearer, more detailed visuals than smaller displays, reducing eye strain during long inspections and making it easier to spot minor defects.
Yes, the camera head is detachable and field-serviceable, allowing quick replacement if damaged—minimizing downtime on job sites.
It is optimized for pipes 2” to 6” (50mm-150mm) in diameter, making it versatile for both residential plumbing and medium-sized municipal sewers.
The 9000mAh Li-ion battery offers 5-6 hours of continuous use. A car charger is included for recharging on the go, ensuring uninterrupted operation during full-day projects.
Yes, the camera head has an IP68 rating and withstands up to 3bar pressure (~30 meters depth), making it safe for submerged pipe inspections.
