Endoscope probe Voltcraft BS-3.9 3.9 mm Ø, 1 m length, QVGA camera, waterproof, swivel function, LED lighting

The Voltcraft BS-3.9 endoscope probe is a compact inspection camera with a 3.9 mm diameter head and a 1 m flexible cable. Equipped with a QVGA sensor in a waterproof housing, the probe delivers live visual access to narrow or confined spaces. Integrated LED lighting ensures illumination of dark areas, while the swivel function allows adjustable viewing angles for precise inspection and diagnostics.

Advantages

The small 3.9 mm diameter head enables entry into very tight openings and narrow bores. The QVGA camera provides sufficient image detail for general inspection tasks while keeping data and power requirements low. A waterproof housing increases durability and allows use in damp or wet environments. The swivel function offers flexible orientation of the camera for thorough visual coverage without repositioning the entire probe. Built-in LEDs provide adjustable illumination close to the inspection area.

How to use

Connect the probe according to the device compatibility instructions and power it on. Gently insert the 3.9 mm camera head into the inspection area, guiding the flexible cable while observing the live image on the connected display. Use the swivel function to change the camera orientation and direct the integrated LEDs to clearly illuminate the target. Withdraw the probe slowly after inspection, rinsing or drying the camera head if it has been exposed to liquids.

Usage recommendations

For reliable results, verify compatibility with your display or recording device before use. Avoid excessive bending or twisting of the cable; use the swivel to adjust view rather than applying force to the probe head. After exposure to liquids, dry the probe thoroughly and inspect the housing for damage. Store the cable coiled loosely to maintain flexibility and prevent kinks.
