500m Borehole Camera

Product Overview

For geological exploration, geotechnical engineering and water‑well maintenance, our 500m borehole camera delivers professional‑grade downhole inspection. Nevertheless, traditional borehole inspection brings notable drawbacks such as blind viewing angles and blurry footage. As such, field crews often struggle to identify hidden underground defects with full confidence. Fortunately, this field‑proven inspection hardware delivers stable real‑time HD monitoring and resolves these common pain points.

Specifically, it captures a wide range of underground failure modes: borehole wall cracks, casing misalignment, well collapse, filter‑pipe blockage and sand outflow. Apart from well‑repair assignments, operators can deploy this unit for oilfield inspection, freezing‑hole testing and construction‑quality acceptance. Accordingly, site operators, geological teams and engineering contractors frequently select this model for reliable underground site assessment.

Core Product Features

High‑Definition Low‑Light Imaging

High‑precision sensors pair with intelligently dimmable LED lights inside this borehole camera. Given this robust hardware setup, operators capture true‑color HD videos even deep within pitch‑dark boreholes. Furthermore, its soft‑balanced lighting eliminates shadows, blurriness and harsh light reflection. Thanks to this feature set, field staff evaluate underground conditions with outstanding precision.

Heavy‑Duty Pressure‑Resistant Probe

Strict factory pressure‑sealing validation is completed for every stainless‑steel probe. To begin with, it supports detection depths up to 3000 meters and withstands 25 MPa working pressure. In addition, tempered‑glass lenses and anti‑corrosion structures stabilize probe performance under high‑temperature, corrosive underground surroundings.

360‑Degree Zero‑Blind‑Angle Rotation

This compact 79 mm rotary probe supports vertical travel plus full 360‑degree horizontal spinning for flexible observation. Whenever close‑range inspection is needed, operators can pause rotation at any target position. For example, users can zoom in on fine cracks or blockages missed by ordinary inspection tools.

On‑Site Real‑Time Monitoring System

A 12‑inch LED display is built inside its matched aluminum‑alloy control box. Consequently, live downhole footage transmits directly to field workers on‑site. Beyond real‑time viewing capability, users may record and archive video files locally for engineering analysis and formal project documentation.

Field‑Friendly Portable Build

Military‑grade waterproof cables work alongside an automatic‑brake electric winch. As a result, the complete inspection system remains compact and easy to transport. Even across rough outdoor terrain, integrated waterproof and pressure‑proof construction greatly lowers unexpected equipment‑failure risks.

Reliable Data for Well Maintenance

Field teams gain intuitive visual reference for all on‑site operations from crystal‑clear real‑time footage. With these visual records in hand, engineering teams carry out fault analysis, defect positioning and quality verification. Meanwhile, overall detection efficiency rises substantially while human‑caused operational errors drop sharply.

Product Advantages

Flexible Depth Customization

Multiple cable‑length options exist to satisfy diverse project‑specific requirements. To illustrate, available specifications cover 50 m, 100 m, 200 m up to 2000 meters. Depending on actual site conditions, buyers can select suitable cable sizes for their respective assignments.

Multi‑Voltage & Low‑Power Design

DC 12V, AC 220V and AC 380V input standards are all accepted by our main control box. Even under unstable power‑supply conditions at construction sites, this unit maintains steady operation. What is more, total power consumption stays at merely 20 W to support hours of continuous field operation.

Adjustable LED Illumination

Eighteen to twenty‑four high‑power cold‑light LED beads are embedded into the probe body. These components produce uniform, flicker‑free illumination across the full field‑of‑view. Simultaneously, intelligent dimming logic avoids over‑exposure and dark dead zones in deep borehole environments.

Long‑Term Stable Performance

Potential circuit‑fault incidents get reduced by premium industrial‑grade electronic components. Furthermore, solid embedded program modules enhance long‑term system durability. For this reason, this hardware demands minimal routine maintenance for extended outdoor engineering assignments.

Typical Application Scenarios

Tangible practical value is delivered by our 500m borehole camera across many industrial projects. First and foremost, it serves water‑well inspection, oilfield downhole checking, geological survey, foundation assessment, freezing‑hole monitoring and construction‑quality acceptance. Above all, engineering firms, geological institutes and oil‑field contractors rely heavily on this inspection equipment.

FAQ

• What is the maximum detection depth and pressure resistance of this borehole camera?
  Capable of 25 MPa maximum working pressure, this inspection camera runs reliably for deep‑water detection as far as 3000 meters. Engineers may select customizable depth ranges spanning 50 m‑2000 m to match diverse shallow‑hole and deep‑hole engineering projects.
• Can the camera deliver clear images in completely dark boreholes?
  Eighteen‑to‑twenty‑four high‑power dimmable cold‑light LED beads are built within the probe. Thanks to its intelligent dimming system, users get uniform, flicker‑free and soft illumination. Over‑exposure and dark blind spots get effectively avoided, while high‑definition true‑color imaging holds steady within pitch‑dark underground surroundings.
• What power supply modes does the device support?
  Complex outdoor and construction‑site environments are well accommodated by the main control box via three universal power inputs: DC 12V, AC 220V and AC 380V. Only 20 W ultra‑low power is consumed during operation. Long‑hour continuous work becomes achievable, cutting energy‑consumption costs for field deployment.

• Is the probe durable for harsh underground working conditions?
  High‑grade stainless‑steel forms the full probe body, paired with shatter‑proof tempered‑steel glass lenses. Waterproof, high‑pressure and high‑temperature resistant performance comes after strict factory pressure validation. Zero water seepage and stable performance stay guaranteed amid severe underground operating scenarios.
• Does the 360° rotary probe support local detailed observation?
  Free 360° horizontal rotation plus vertical lifting come with this 79 mm rotary probe, with pause available at any arbitrary angle. Cracked walls, blocked pipes and other defect zones can be targeted by engineers for close‑up inspection. Such design eliminates blind‑spot drawbacks common to conventional fixed‑view cameras.
• Is the equipment easy to carry and operate on site?
  Compact lightweight construction defines this unit, alongside an automatic‑brake electric winch for effortless, low‑labor handling. Real‑time on‑site preview, video recording and data archiving are accessible through its integrated aluminum‑alloy control box with 12‑inch large screen. No sophisticated professional training is demanded for daily operations.
