GT75BXA PTZ manhole inspection camera — the pole camera system designed for complete visual inspection of manholes, tanks, containers and pipes with diameters ranging from 80mm to 6000mm, without lowering personnel into the space. With a 75mm or 90mm PTZ head, 10x optical zoom combined with 10x electronic zoom and infinite 360° rotation with 180° tilt, this PTZ manhole inspection camera fully covers the interior surface of any inaccessible enclosed space, from municipal manholes to large industrial storage tanks.
Unlike crawlers that advance along the bottom of the pipe or push rods that follow the tube axis, a pole-mounted PTZ manhole inspection camera descends vertically from the surface and rotates the camera in all directions — providing a complete image of the walls, floor and lateral connections of the manhole or tank without any movement by the operator. Corrosion resistance and IP68 sealing allow use in manholes with toxic atmospheres, flammable gases or aggressive chemical environments in the petrochemical and gas industries. Key Advantages of the GT75BXA PTZ Manhole Inspection Camera
• Maximum diameter 6000mm — the widest range in the entire Jiutai lineup: GT75BXA inspects spaces with diameters from 80mm to 6000mm — from narrow pipes to industrial tanks 6 meters in diameter. No other system in the Jiutai lineup available at Uzinex covers diameters above 3500mm. This makes the GT75BXA the only PTZ manhole inspection camera suitable for storage tanks, large containers and the technical galleries of municipal infrastructure.
• 10x optical zoom + 10x electronic zoom — ultra-detailed viewing: Combining 10x optical zoom with 10x electronic zoom delivers a total magnification of 100x relative to the normal field of view. Tiny defects on tank walls, incipient cracks in liners and pitting corrosion on internal metal surfaces become visible and documentable from a distance, without physically bringing the camera closer.
• Infinite 360° rotation + 180° tilt — zero blind angles: The PTZ head rotates continuously 360° and tilts 180°, fully covering the interior surface of the manhole or tank from any angle — vertical walls, floor, top cap and lateral connections — without repositioning the pole or changing the descent depth.
• Confined space inspection without personnel at risk: Occupational health and safety regulations restrict or prohibit personnel entry into manholes with hazardous atmospheres (H₂S, CH₄, CO, solvent vapors). This PTZ manhole inspection camera fully documents the interior condition of any confined space from the surface, eliminating the risk of accidents from asphyxiation or explosion and reducing the duration of preparation work for confined space entry.
• Corrosion resistance for petrochemical and gas applications: The camera body and pole are anti-corrosion treated, withstanding atmospheres with hydrocarbons, H₂S, acid vapors and other industrial gases present in industrial sewer manholes, hydrocarbon tanks and petrochemical pipes. IP68 ensures sealing against full immersion for manholes with a high liquid level.
• 75mm or 90mm camera head — fits through standard access openings: The 75mm or 90mm diameter of the PTZ head allows insertion through the standard openings of municipal manhole covers (500mm) and through the inspection ports of industrial tanks and containers, without removing the cover or modifying the access opening.
• 6 adjustable LEDs — adaptable lighting: The 6 LEDs with adjustable brightness provide uniform illumination of large interior spaces, from small 80mm manholes to 6000mm tanks — adapting the light intensity to the size and type of the inspected interior surface.
• Portable, battery-powered — autonomous field operation: The system is battery-powered and fully portable, with no need to connect to the power grid in the field. Control is handled from the 10 inch screen, with all PTZ, zoom and lighting functions accessible directly from the control unit.

Applications — Where the GT75BXA PTZ Manhole Inspection Camera Is Used
A PTZ manhole inspection camera from the GT75BXA series is the standard tool of water and sewer companies, gas network operators and industrial inspection firms for checking the interior condition of manholes without personnel entry. Municipal sewer manholes 1–5m deep, with toxic H₂S or CO atmospheres, are fully assessed from the surface in 5–10 minutes: the pole descends, the PTZ camera rotates 360° and documents the condition of the walls, lateral connections and floor of the manhole with 10x zoom for fine detail defects.
In the petrochemical, natural gas and industrial chemistry sectors, this PTZ manhole inspection camera inspects the interior of storage tanks, process containers and large-diameter pipes (up to 6000mm) without fully opening the tank or preparing a confined space entry. The corrosion resistance of the body and pole allows use in environments with hydrocarbon vapors, H₂S and acid vapors where equipment without anti-corrosion treatment deteriorates rapidly. Explore the full range of Uzinex industrial equipment for inspection solutions across all types of pipes and enclosed spaces.
Builders accepting newly built manholes, underground infrastructure rehabilitation companies and municipal technical departments use systems such as the GT75BXA PTZ manhole inspection camera to document the internal condition at project handover and for annual maintenance audits, in accordance with international standards for video inspection of pipes and confined spaces. Video reports with dual 10x+10x zoom provide the detailed documentation required for technical files and insurance reports. How It Works — Manhole Inspection with the GT75BXA
• Preparation and lowering of the pole: The operator opens the manhole cover or the access port of the tank and inserts the pole with the 75mm or 90mm PTZ head from the surface. Personnel entry into the space is not required — the operator remains at ground level throughout the inspection.
• PTZ control from the 10 inch screen: The pole is lowered to the desired depth, and the operator commands the 360° rotation, 180° tilt and zoom from the 10 inch control screen. The live Full HD image is displayed in real time on screen with all the details of the inspected space.
• Systematic inspection with dual 10x+10x zoom: The operator rotates the camera 360° at each depth level, documenting the walls, joints, lateral connections and floor of the manhole. When a suspect defect is identified, the 10x optical zoom allows close-up viewing for precise documentation without changing the pole depth.
• Adaptive lighting adjustment: The 6 adjustable LEDs are tuned for optimal illumination depending on the size of the space and the type of internal surface — lower intensity for small spaces with high reflectivity, maximum intensity for large, dark tanks.
• Recording and documentation: Video recordings and photos are saved to a USB disk for archiving and reporting. All documented defects — cracks, corrosion, infiltration, deposits, faulty connections — are captured clearly thanks to the dual zoom.
Frequently Asked Questions about the GT75BXA PTZ Manhole Inspection Camera
What is a pole-mounted PTZ camera and how does it differ from a CCTV crawler?
A pole-mounted PTZ manhole inspection camera descends vertically from the surface and rotates the PTZ camera in all directions to inspect a wide space from above — ideal for manholes, tanks and containers. A CCTV crawler advances horizontally through the pipe to inspect the tubular run. The GT75BXA covers spaces with diameters up to 6000mm that a crawler cannot inspect efficiently, and it allows inspection without personnel entering the confined space. Can the GT75BXA be used in manholes with hazardous atmospheres (H₂S, CH₄)?
Yes. This PTZ manhole inspection camera — with an anti-corrosion treated body and pole and IP68 sealing — operates in atmospheres with H₂S, methane vapors, CO and hydrocarbon vapors, without exposing the operator to risk. The operator remains at the surface throughout the inspection. Compliance with the safety procedures specific to confined spaces is recommended when preparing access. What is the maximum diameter the GT75BXA can inspect?
The GT75BXA inspects spaces with diameters up to 6000mm — industrial storage tanks, large process containers and technical galleries with a circular cross-section. This is the maximum limit across the entire Jiutai lineup and far exceeds that of any crawler in the lineup (maximum 3500mm on the GT108 and GT108Pro). What is the minimum access opening diameter for inserting the pole?
The 75mm PTZ head requires an access opening of at least 80mm internal diameter — smaller than the standard diameter of municipal manhole covers (500mm) and of the inspection ports of industrial tanks. The 90mm version requires a minimum of 95mm. Both versions fit through all standard access openings in sewer, petroleum, gas and chemical industry infrastructure. How does the GT75BXA compare with the lineup's CCTV crawlers for manhole inspection?
CCTV crawlers — GT108, GT108Pro — are the optimal solution for inspecting the pipe section between manholes. The GT75BXA is the solution for inspecting the interior of the manhole itself: walls, floor, lateral connections, the condition of ladders and guide rails — documentation required for the structural assessment of sewer infrastructure, complementary to inspecting the pipe section with the crawler.
