GT104WS Ultra HD sewer inspection camera — the top of the Jiutai range, designed for teams that accept no compromise on image quality or field reliability. With a 4-megapixel sensor and 2560×1600 resolution, this Ultra HD sewer inspection camera delivers detail twice as fine as standard Full HD systems, allowing the identification of incipient defects before they become costly structural failures.
The six-wheel drive, the camera head with 180 mm electric lift, the wireless transmission between tablet and crawler, and the battery with an 8-hour runtime make the GT104WS an Ultra HD sewer inspection camera built for long-duration missions, over long sections, in networks with complex geometry. It covers pipes with diameters between 150 mm and 3.000 mm — from secondary collectors to large-diameter main channels. Key advantages of the GT104WS Ultra HD sewer inspection camera
• 4-megapixel camera, 2560×1600 Ultra HD resolution: Compared with the Full HD 2MP standard of the other systems in the range, this Ultra HD sewer inspection camera offers twice as many pixels — microcracks, weld defects and incipient corrosion become clearly visible, without ambiguity, directly on the 12-inch tablet screen.
• Camera head with 180 mm electric lift (Elevator): The exclusive Elevator function allows the camera head to be optically raised by up to 180 mm above the crawler's travel axis. The result: complete viewing of the upper wall of the pipe in large-diameter pipes, without repositioning the robot and without blind angles at the upper crown.
• Hexapod drive — six independent drive wheels: The six-wheel system ensures superior grip and traction force on surfaces with deposits, in pipes with compact sediment or irregular geometry, overcoming the obstacles that block four-wheel crawlers.
• Wireless transmission between tablet and crawler: Unlike systems with a fixed wired connection to the controller, the GT104WS transmits the image and commands wirelessly — the operator can move freely around the manhole without being constrained by the position of the control box.
• 8-hour runtime — the longest in the range: The integrated battery of the 12-inch tablet provides 8 hours of continuous operation — enough for a full day of inspection across several sections, without recharging pauses and without an additional generator in the field.
• Automatic defect recognition (integrated software): The system includes defect-interpretation software that automatically identifies cracks, deformations, blockages and ruptures by type, marks them in the recording and includes them directly in the inspection report generated with a single click.
• One-click defogging function: In pipes with vapour or wall condensation, the one-click defog function clears the image instantly, eliminating the need to stop and reposition the crawler to re-document the affected area.
• 150 kg Kevlar cable — up to 300 m: The professional Kevlar cable (150 kg tensile strength, resistant to water, oil and abrasion) ensures connection integrity over sections of up to 300 m in networks with difficult environmental conditions.

Applications — where the GT104WS Ultra HD sewer inspection camera is used
An Ultra HD sewer inspection camera from the GT104WS series is the tool chosen by infrastructure operators with a legal obligation to precisely document the condition of domestic, stormwater and industrial sewer networks, in accordance with the DIN EN 13508-2 standards and national video inspection standards. The 4MP resolution allows the identification of grade-I defects — microcracks, point infiltrations, incipient joint separations — that Full HD systems lose in image noise.
In the petrochemical, energy and natural gas industries, this Ultra HD sewer inspection camera is used for integrity audits of process pipes with diameters between 150 mm and 3.000 mm, in difficult environmental conditions — steam, hydrocarbon vapours, dense sludge — where the defogging function and the Ultra HD resolution are decisive for the quality of documentation. The hexapod drive overcomes the obstacles that block standard crawlers, reducing failed sessions and costly repeats. Explore the full range of Uzinex industrial equipment for complementary diagnostic and intervention solutions.
Local authorities, county water companies and contractors carrying out EU-funded works use Ultra HD sewer inspection camera systems for the final acceptance of new works and for the pre-rehabilitation assessments required by PNRR procedures, in accordance with international standards for non-destructive video inspection. The reports generated automatically with a single click include Ultra HD video, marked images, GPS localization of defects and the real-time gradient chart. How it works — workflow with the GT104WS
• Launch and wireless connection: The crawler is inserted into the pipe through the manhole. The 12-inch tablet connects wirelessly to the crawler — the operator can stand 5–10 m away from the manhole, without being constrained by the controller's signal cable.
• Navigation with hexapod drive: The six independent drive wheels provide forward/reverse travel and free steering, overcoming thresholds, compact deposits and irregular geometries that would block a four-wheel crawler.
• Ultra HD inspection with electric lift: The operator electrically raises the camera head by up to 180 mm to view the upper crown of large pipes, rotates 360° and adjusts the 10x zoom for precise documentation of any suspect defect.
• Automatic recognition and defect annotation: The integrated software automatically identifies the defect type and marks it in real time. The operator validates or completes the annotations directly from the 12-inch tablet, without external software.
• Defogging and continuation of inspection: When condensation or steam appears in the pipe, a single click on the defog function restores image clarity, without stopping the session or repositioning the crawler.
• One-click report generation: At the end of the session, the complete report — Ultra HD 4MP video, marked images, defect localization, gradient angle, distance travelled — is generated automatically and exported via HDMI or stored on the 128 GB internal memory, ready to hand over to the client.
Frequently asked questions about the GT104WS Ultra HD sewer inspection camera
Why 4MP versus 2MP — what is the real difference in the field?
A 4MP Ultra HD sewer inspection camera (2560×1600) records twice as many pixels as the 2MP Full HD standard (1920×1080). The practical difference: microcracks under 0,5 mm, point infiltrations and incipient joint separations become clearly visible and documentable. With 2MP systems, these grade-I defects appear as image noise or are completely invisible, requiring a second inspection session with higher-performance equipment. What does the Elevator function mean and when is it used?
The Elevator function electrically raises the camera head by up to 180 mm above the crawler's travel axis. It is used in large-diameter pipes (over 600 mm), where the camera at ground level does not visually cover the upper crown of the pipe. The electric lift eliminates the need to introduce a second piece of equipment or to reposition the crawler in order to document the upper area of the cross section. How many hours can the GT104WS operate without recharging?
The integrated tablet battery provides 8 hours of continuous operation — the longest runtime in the Jiutai range. This allows the completion of an entire daily inspection programme across several sections without recharging pauses. The crawler is powered through the Kevlar cable from the external source of the electric reel. How does automatic defect recognition work?
The integrated software analyses the Ultra HD image in real time and automatically identifies the standard defect types: longitudinal cracks, circumferential cracks, deformations, blockages, ruptures and infiltrations. Each detected defect is marked with type, location (footage) and orientation, and automatically included in the inspection report generated with a single click — without manual post-processing and without external software. How does the GT104WS compare with the GT102B or GT108?
This Ultra HD sewer inspection camera is the top of the range: 4MP versus the 2MP Full HD of the other systems, six wheels versus four, the Elevator function, wireless transmission and 8h runtime. The GT102B is the portable 6 kg solution for 150–2000 mm, optimal for routine inspections. The GT104WS is the choice for projects where Ultra HD documentation and automatic reports are contractual or regulatory requirements.
