Endoscope cameras: finally a glimpse into hard-to-reach areas

Endoscopy is known from the field of medicine, but in the meantime the technique of minimally invasive examination of technical cavities has also become common in trade and industry.
Manufacturers of endoscope cameras have specialized the respective models, so that everyone, from the hobby craftsman to the professional plant manufacturer, can find a suitable model for his purposes.

This is what the endoscope camera is all about

The structure of an endoscope camera is essentially always the same: In addition to light sources for illuminating dark areas and light guides, image guides and sensors for camera shots are always installed. A central component is also the optics with which the photo and video recordings are made.

In this guide we explain three typical application areas and show how these can best be used.


1. a clogged pipe

One of the classic applications of an endoscope camera is a blocked tube. If the drain cleaner no longer helps and you do not know exactly where the problem lies, you can look directly in the pipe and locate the problem.

The gooseneck of the camera is inserted directly into the tube – with the integrated lights, which are built into the devices, you can ensure sufficient exposure.

Once the problem has been found, cameras such as the RND 355-00009 allow you to attach a hook to the camera head and pull out the cause of the problem directly, for example if it is a tuft of hair. Otherwise it is advisable to photograph or film the problem area from different positions – and to consider the further procedure on the basis of the material.

A solution to this problem could be, for example, a dirt milling machine – a how-to on this topic can be found here.


2. car body construction

In addition to clogged tubes, endoscope cameras can also show problem areas in body construction. The small and flexible cameras are used to inspect difficult-to-view components on vehicles that would otherwise have to be removed at great expense.

Photographic or video recordings of these locations can be used to determine whether the components are still in order or whether corrosion or rust has already occurred.
If necessary, the component can be repaired while it is still installed. The progress of the repair can be documented with the camera.

Endoscope cameras such as the PEAKTECH 5600 are ideal for these activities because it is also IP67-certified – it is therefore particularly well protected against dust and dirt.

Another camera specially designed for vehicle inspection is the ENDO S12. This camera is operated on a small roller carriage and is therefore particularly suitable for inspecting underfloors.


3. machine and plant construction

In addition to car body construction and pipe inspections, endoscope cameras are increasingly used in industrial machine and plant construction. The cameras are not only used for fault detection, but also for maintenance, repair and quality control.

As in the previous examples, the endoscope cameras are used for non-visible plant sections that would otherwise have to be dismantled. Cameras with an integrated rotation control are preferred here in order to obtain a holistic image. In industrial rooms, care should also be taken to ensure that the camera is robust enough to withstand particularly high or low ambient temperatures.

In addition, the focus range of the camera should be very low, so that the photo and video recordings still have the necessary sharpness even in very narrow rooms.

The ENDO S06, for example, offers all these features. It can be used at temperatures between -10° and +60° C, can rotate up to 180° and has a focusing range of only 2 to 5 cm.

Investors can make long-term savings

Of course, the purchase of an endoscope camera means an investment for the time being – but the inexpensive models are already available from about 70€ to buy. In the long run one will be able to save by the employment of the cameras, since one can save for example the pipe cleaning company or the expensive removal of construction units.
