The 21mm 9 Inch High Brightness Sewer Inspection Camera combines compact size with powerful performance, addressing the gap in small-diameter pipe diagnostics where larger 29mm cameras cannot fit. Its slender 21mm camera head—measuring just 0.83 inches in diameter—accesses tight spaces like 1.5-inch residential drains, narrow industrial micro-pipelines, and pipe fittings (like reducers or tees) that block larger devices. The 9-inch high-brightness LCD display (mounted on a portable, ergonomic handle) ensures clear visibility of defects even in low-light conditions, eliminating the need for external monitors or additional lighting. This all-in-one system integrates 1080P pipe inspection camera technology with user-friendly controls (like one-touch recording and zoom) and a rechargeable battery—making it ideal for both field inspections (by contractors) and on-site maintenance (by facility managers). Unlike bulky inspection systems, it weighs only 2.5kg, allowing operators to carry it up stairs or into tight crawl spaces with ease.
21mm Ultra-Compact Camera Head: Crafted from lightweight yet durable 304# stainless steel, the camera head navigates pipes as small as 1.5 inches (40mm) in diameter—including narrow residential drains, dental office suction lines, and industrial micro-pipelines. Its slim profile also allows it to pass through pipe reducers (from 2 inches to 1.5 inches) and tight fittings that would block larger 29mm camera heads. The head’s rounded edges prevent it from getting caught on pipe burrs or sediment.
9 Inch High-Brightness LCD: The display delivers 700 nits of brightness—outperforming standard 400-nit displays by 40%—and features an anti-glare coating that maintains visibility in direct sunlight (like outdoor construction sites) or well-lit industrial facilities. It also has a 178° wide viewing angle, enabling multiple team members to review footage simultaneously in the field. The screen’s resolution (1920×1080 pixels) ensures crisp, detailed images of even small defects (like 1mm cracks).
Scratch Resistant Sapphire Lens: The camera’s lens is made from synthetic sapphire, which preserves high-definition resolution by resisting scratches from sediment (like sand or gravel), pipe debris (like metal shavings), and rough pipe interiors (like concrete or clay). In field tests, the lens retained clarity even after being dragged across concrete pipes for 500 meters, while glass lenses showed significant scratching and image blurring.
Incorporated Light Ring: Surrounding the lens is a ring of 12 adjustable white LEDs (each with a lifespan of 50,000 hours) that offer 5 brightness levels (from 100 to 500 lumens). This ring illuminates pipe interiors up to 3 meters ahead, eliminating shadowing and ensuring even light distribution—critical for detecting leaks or corrosion in dark, narrow pipes. The LEDs are also energy-efficient, minimizing battery drain during long inspections.
Stainless Steel Housing & IP68 Rating: The camera head’s 304# stainless steel housing withstands corrosion from sewer chemicals (like hydrogen sulfide) and prevents rusting, while the full IP68 waterproof rating allows submersion up to 10 meters for 72 hours. This ensures the camera works reliably in fully flooded pipes (like storm drains after rain) or wet industrial environments (like food processing plants).
This camera excels in small-diameter pipe scenarios where precision and portability are key:
Small-Diameter Sanitary Pipes: Inspecting 1.5–6 inch household and commercial drains to identify common issues—like kitchen sink clogs from food particles, bathroom drain blockages from hair and soap scum, or toilet drain leaks caused by cracked pipes. It is also used by plumbers to verify repairs (like pipe patching or root removal) without re-excavating.
Storm Drain Laterals: Accessing narrow branches of stormwater systems (1.5–4 inches in diameter) to identify blockages that could cause urban flooding. The camera’s compact size allows it to navigate the small-diameter laterals that connect to main storm drains, while the high-brightness display ensures visibility in dark, wet conditions.
Industrial Micro-Pipelines: Diagnosing issues in small-diameter industrial pipes, such as pharmaceutical manufacturing lines (where detecting small leaks is critical for maintaining sterile conditions), automotive factory coolant lines (to find corrosion), or printing press ink lines (to locate clogs). The camera’s high-definition resolution and sapphire lens ensure it can detect even tiny defects that could disrupt production.
Q: What resolution does the camera capture?
A: It records video and takes still images in full 1080P HD resolution (1920×1080 pixels), ensuring crisp, detailed imagery for detailed defect analysis and reporting. The camera also supports 720P recording for longer battery life (when extended inspections are needed). Footage can be stored on a microSD card (up to 128GB, sold separately) or transferred to a computer via USB for further analysis or client reports.
Q: How long does the battery last during inspections?
A: The integrated 5,000mAh lithium-ion battery provides up to 6 hours of continuous operation (when recording in 1080P with LEDs at 50% brightness)—sufficient for full-day inspections. For longer projects, the battery can be swapped with a spare (sold separately) in under 1 minute. It can also be fully recharged in 2.5 hours using the included fast-charging adapter, minimizing downtime between inspections.
Q: Can the display be viewed in direct sunlight?
A: Yes, the high-brightness screen (700 nits) and anti-glare coating ensure visibility even in direct sunlight—unlike standard displays that become washed out. In outdoor tests (at midday in summer), operators could clearly view footage without using a shade or adjusting their position. The display also has a backlight adjustment feature, allowing operators to dim it in low-light environments (like crawl spaces) to reduce eye strain.
