About Inspection Cameras

Inspection cameras, also known as borescopes or endoscopes, are essential diagnostic tools that allow tradespeople and engineers to visually inspect hard-to-reach or enclosed spaces without costly dismantling work. These sophisticated devices feature a flexible or rigid probe with an integrated camera head and LED lighting, connected to a display screen or mobile device, enabling visual examination inside pipes, cavities, engines, electrical conduits, and other inaccessible areas. Modern inspection cameras have revolutionised fault-finding and preventative maintenance across numerous trades, saving both time and money on site work.

The selection at Tooled-Up.com includes everything from compact handheld models perfect for quick inspections to professional-grade systems with advanced features such as Wi-Fi connectivity, dual cameras, thermal imaging capabilities, and interchangeable probe heads. Leading manufacturers like Bosch, Ridgid, Sealey, and Draper offer inspection cameras with varying probe diameters from 3.9mm for extremely tight spaces up to 8.5mm for enhanced image quality and durability. Whether you're a plumber investigating blocked drains, an electrician checking conduit runs, or a motor mechanic examining engine cylinders, there's an inspection camera suited to your specific requirements.

Many modern inspection cameras now feature rechargeable batteries for cordless convenience, high-resolution displays for clear image quality, and recording capabilities that allow you to capture photos and videos for client reports or quality assurance documentation. The latest models from Bosch Professional include innovative thermal imaging cameras that detect heat signatures, ideal for identifying electrical faults, insulation problems, and water ingress issues that wouldn't be visible to a standard optical camera.

Jargon Buster

• Borescope/Boroscope – A rigid or flexible inspection device with an optical system or camera for viewing inside confined spaces. Often used interchangeably with inspection camera.
• Probe Diameter – The width of the camera head, typically ranging from 3.9mm to 17mm. Smaller diameters access tighter spaces but may compromise image quality and durability.
• IP Rating – Ingress Protection rating indicating the camera probe's resistance to dust and water. IP67 or IP68 ratings are common for professional inspection cameras used in wet or dirty environments.
• Articulation – The ability to control the direction of the camera head, usually via a joystick or control mechanism. Articulating probes allow you to navigate bends and look around corners.
• Field of View (FOV) – The observable area visible through the camera lens, typically measured in degrees. Wider angles (120°+) capture more of the inspection area but may distort the image at the edges.
• SeeSnake Technology – Ridgid's proprietary push-rod camera system designed specifically for plumbing and drainage inspections, featuring durable construction and sonde transmitters for pipe location.

How to Choose the Right Inspection Cameras

Selecting the appropriate inspection camera depends on several key factors:

Probe Diameter and Cable Length: Consider the smallest access point you need to navigate and the depth of inspection required. Draper's range includes 3.9mm probes for extremely tight spaces, 5.5mm for general use, and 8.5mm for improved durability and image quality. Cable lengths typically range from 1 metre for basic inspections to 5 metres or more for deep drainage work or extensive cavity investigations.

Display Type: Choose between integrated LCD screens, tablet displays, or smartphone connectivity via Wi-Fi. Models like the Sealey VS8113 offer Wi-Fi connectivity, allowing you to use your existing mobile device and easily share images with clients or colleagues. Dedicated screens provide better visibility in bright sunlight on site work.

Image Quality and Lighting: Look for cameras with adequate resolution and adjustable LED lighting. Higher-end models from Bosch Professional offer superior image sensors and powerful illumination for clearer diagnostics in dark environments.

Camera Head Features: Some models available from Tooled-Up include articulating heads for steering around bends, dual cameras for simultaneous viewing angles, or specialised thermal imaging capabilities like the Bosch GTC 400 C for detecting temperature variations.

Recording Capability: If you need to document findings for reports, insurance claims, or quality assurance, ensure the camera can capture photos and videos to internal storage or SD cards.

Durability and Protection: Professional tradespeople should prioritise robust construction with high IP ratings (IP67 or IP68) for waterproofing and dust resistance. The probe cable should be reinforced to withstand site conditions.

Power Supply: Rechargeable lithium-ion batteries offer cordless convenience, whilst mains-powered units provide unlimited runtime for extended inspections.

Safety Information

When using inspection cameras, always observe these safety precautions:

Electrical Safety: Never insert inspection camera probes into live electrical equipment or panels without first isolating the power supply. Even though many cameras operate on low-voltage rechargeable batteries, the probe could create a short circuit or expose you to dangerous voltages. Always follow safe isolation procedures in accordance with BS 7671 wiring regulations and verify 240v circuits are dead before inspection.

Contaminated Environments: When inspecting drains, sewers, or areas potentially containing hazardous substances, be aware of COSHH regulations. Wear appropriate PPE including gloves and eye protection. Thoroughly clean and disinfect probe heads after use in contaminated environments to prevent cross-contamination and health risks.

Confined Spaces: If using inspection cameras as part of confined space work, ensure proper risk assessments are completed and all HSE guidelines for confined space entry are followed, even if the camera reduces the need for physical access.

Probe Damage: Avoid forcing probes into spaces where they become stuck or bent, as this can damage the delicate internal components and create sharp edges that may cause injury during extraction.

Frequently Asked Questions
