GTV300 Borehole & Well Inspection Camera | Alloy Steel | 360° | Patented LED | AC/DC

GTV300 borehole & well inspection camera — the portable Full HD system for the visual inspection of water wells, geotechnical boreholes, hydrogeological observation piles and underground bores, with an alloy steel housing resistant to pressure and high temperatures, a 120° wide-angle field of view with a patented angle wider than equivalent imported equipment, and 360° rotation for complete documentation of the borehole walls from the surface. With a 38mm camera head lowered on the electric drum, this borehole & well inspection camera delivers a real-time Full HD 1920×1080 image on the 10 inch IPS screen, at any depth accessible from the surface.

Unlike telescopic pole systems and periscopes that inspect manholes and horizontal pipes, a GTV300-type borehole & well inspection camera descends vertically into the narrow circular geometry of boreholes and wells — where neither a crawler nor a telescopic rod can enter. The alloy steel housing protects the camera against impact with the borehole walls and against the hydrostatic pressure of the water column, while AC/DC compatibility ensures autonomous field operation without mains power. Key Advantages of the GTV300 Borehole & Well Inspection Camera

• Anti-collision alloy steel housing — designed for boreholes and wells: The camera body in alloy steel withstands impact with the borehole walls during descent, the abrasion of mineral deposits and the hydrostatic pressure of the water column in deep wells. Unlike the plastic or aluminium housings of sewer cameras, this borehole & well inspection camera handles the mechanical stresses specific to vertical descent into 38mm-diameter boreholes.

• Resistance to high temperatures and pressures: The high temperature and pressure resistance specification allows use in geothermal boreholes, in wells located in zones with a high geothermal gradient and in bores with significant hydrostatic pressure at great depths — conditions that exceed the limits of standard sewer or manhole inspection cameras.

• Patented 120° field of view — wider than imported equipment: The 120° wide-angle optics is a patented Jiutai technology, with a field of view explicitly wider than that of equivalent imported equipment. In 38mm-diameter boreholes, a wider field of view means more wall is visible simultaneously and fewer descent positions are required for complete documentation of the cross section.

• Patented LED lighting — maximum clarity at depth: The LED lighting system with adjustable brightness is a patented Jiutai technology, designed to ensure image clarity at great depths where natural light is zero and where uncontrolled reflections would degrade the quality of the visual documentation of geological formations and borehole wall defects.

• 360° rotation + wide-angle view — complete borehole documentation: The camera head rotates continuously 360° for complete documentation of the internal circumference of the borehole at every depth level. Combining 360° rotation with the 120° wide-angle field of view ensures total coverage of the borehole walls without repeating the descent position.

• Electric drum with depth counter — precise footage: The electric drum lowers and recovers the camera with an integrated depth counter — critical information for correlating visual anomalies and defects with the exact depth in the geological profile or in the borehole casing column.

• AC/DC compatibility — full field autonomy: The GTV300 operates both from mains power (AC) and from its own battery (DC) — essential for field inspections of geotechnical boreholes and water supply wells in rural or remote areas without electrical supply on site.

• Multiple patents with imported German components — certified quality: The GTV300 integrates Jiutai's own patents and quality components imported from Germany. This combination — patents on wide-angle optics and LED, German precision components — delivers the clearest image available in this category of equipment for borehole and well inspection.

Technical Specifications — GTV300 Borehole & Well Inspection Camera

Applications — Where the GTV300 Borehole & Well Inspection Camera Is Used

A GTV300-series borehole & well inspection camera is the standard tool of geotechnical engineers and drilling companies that carry out inspections of hydrogeological observation boreholes, foundation piles and groundwater table monitoring bores. The 38mm camera descends into standard boreholes with diameters from 50–75mm, documenting the geological formations crossed, the condition of the casing, mineral deposits, cracks and dislocations of the borehole walls — information essential for geotechnical projects, hydrogeological studies and groundwater quality monitoring programs.

Emergency services, seismic search-and-rescue teams and civil protection units use this borehole & well inspection camera for the detection of survivors in wells, boreholes and underground spaces after earthquakes or building collapses — an application explicitly documented by the manufacturer Jiutai. The 38mm camera enters any opening or crack of sufficient diameter, delivering a live image of the underground space without putting rescue personnel at risk.

Aquaculture companies, water supply well operators and irrigation system maintenance service providers use GTV300-type borehole & well inspection camera systems for the annual inspections of groundwater wells — assessing the condition of submersible pumps, intake screens, casing and the level of clogging, in accordance with international standards for video inspection of underground infrastructure. AC/DC compatibility allows field inspections without a generator, using the system's own battery. How It Works — Borehole Inspection with the GTV300

• Equipment preparation and depth counter calibration: The operator positions the GTV300 unit at the mouth of the borehole or well and resets the depth counter to zero. The 38mm camera is checked visually — the alloy steel housing and the IP68 sealing are inspected before the first descent.

• Controlled descent on the electric drum: The electric drum lowers the camera at a controlled speed into the inspected borehole or well. The depth counter displayed on the 10 inch IPS screen continuously tracks the exact depth of the camera head — information saved automatically on the video recording.

• Inspection with 360° rotation and patented LED lighting: At the desired depth, the operator of this borehole & well inspection camera activates the 360° rotation and documents the complete circumference of the borehole. The adjustable LED lighting is calibrated for optimal image clarity at the inspected depth and diameter — a critical setting for visualizing fine geological formations and cracks in the borehole casing.

• Photographing and recording with depth marking: The identified anomalies — cracks, dislocations, mineral deposits, screen blockages, foreign objects — are photographed and video-recorded. The exact depth is marked on each capture for correlation with the geological profile of the borehole or with the casing plan.

• Drum recovery and report generation: The camera is recovered on the drum at a controlled speed. The Full HD recordings with the depth markers are available immediately on the 10 inch screen for field analysis or for export into the geotechnical or hydrological report of the borehole.

Frequently Asked Questions about the GTV300 Borehole & Well Inspection Camera

What types of boreholes and wells can the GTV300 inspect?

The GTV300 inspects any borehole or well with a minimum internal diameter of 40mm: geotechnical and hydrogeological observation boreholes (50–100mm standard diameter), water supply wells (100–300mm), foundation piles with internal casing (100–300mm), groundwater table monitoring bores and geological exploration boreholes. This GTV300 borehole & well inspection camera is not designed for the inspection of horizontal pipes — for those, the Uzinex range of crawlers and push rods is the appropriate solution. Is the alloy steel housing necessary compared to aluminium or plastic?

Yes. During vertical descent into narrow boreholes, the camera periodically strikes the borehole walls — especially in boreholes with deviated casing or with irregular mineral deposits. The alloy steel housing of the GTV300 withstands these repeated impacts without deformation or damage to the IP68 sealing. Plastic housings break on impact; aluminium ones deform permanently, altering the geometry of the camera head and compromising the sealing. Alloy steel maintains structural integrity and IP68 throughout the entire service life of the equipment. The 120° field of view is wider than the competition — what does that mean in practice?

In a borehole with a diameter of 50–75mm, the distance between the camera and the walls is 5–20mm — extremely small. A 90° field of view (standard on sewer cameras) shows a narrow strip of the borehole wall; the patented 120° field of this borehole & well inspection camera covers a larger area of the borehole wall at each position, reducing the number of rotations needed for complete documentation of the circumference and making the inspection faster and more thorough. Can the GTV300 be used for seismic rescue — how does it work?

Yes — the manufacturer explicitly documents the application in seismic rescue and the detection of survivors under rubble. The 38mm camera enters through any crack, breach or opening with a minimum diameter of 40mm in collapsed structures, delivering a live image of the interior space without putting rescue personnel at risk. The patented LED lighting ensures visibility in completely lightless spaces, and the 10 inch IPS screen allows the rescue team to analyze the live image from the surface. How does the GTV300 compare with the GTW06 and GTW106 telescopic pole cameras in the range?

The GTW06 and GTW106 are systems for top-down inspection of manholes and tanks accessible through standard access points (50–600cm diameter). The GTV300 is designed exclusively for boreholes and wells with diameters of 40–300mm and depths of tens or hundreds of metres — geometries inaccessible to telescopic periscopes. The alloy steel housing, the resistance to high hydrostatic pressure and the patented 120° field of view structurally differentiate it from the pole systems intended for surface manholes.
