The K&F Concept is an endoscope camera with two lenses. It is delivered with a sturdy hard case. In addition to the actual endoscope camera, consisting of a control panel about the size of a mobile phone (with a 5" screen) and a mounted endoscope tube, there is a charging cable (USB 3), a mountable support for the control panel, a magnet attachment and a hook attachment for the camera, as well as brief instructions in various versions Languages. A no-name 32GB card is already inserted in the control panel and offers plenty of space for recordings (more on that later). A charger is not included, but any mobile phone charger with a USB port can be used without any problems. The 2600mAh battery was with me fully loaded, so that you could start testing right away. Since an apartment is being renovated in the circle of relatives, there were various possibilities for inspection and recording. The familiarization with the operation works almost without operating instructions. The upper gray rocker is used for the lighting controlled and the photo/video recording is carried out.In the middle of the control panel The mode button (photo/video/playback), the setting button for the camera functions (resolution, date, shutter sound, language, formatting, etc.), the two scroll buttons for the menu settings and the enter button are located in a circle in the middle. In the lower area is the yellow-green rocker with the on/off switch and the button for the rear lighting device (torch replacement for dark environments). For wet environments, the camera hose is well shielded against moisture, the 5 meter hose length is also sufficient for expeditions into remote areas of pipes, shafts, etc. The illumination of the front camera with the 6 LEDs (dimmable) is good, the illumination of the two side cameras consists of only one LED, but this is easily sufficient for close distances! When switching between the three lens systems, the lighting also changes. After you have unraveled the somewhat rigid endoscope tube, you can get started right away. I had set the highest resolution (HD 1920x1080). I took pictures of a cable basket on a ceiling, a narrow pipe, the end of an old water connection and an old chimney. The recordings are sometimes taken with the central front camera, sometimes with one of the two side camera lenses. All recordings looked flawless and perfect on the screen of the control panel. Accordingly, I was disappointed on the computer with a large screen. Depending on the recording, the images are just 50-110 KB in size, so the quality on the screen (despite Full HD) is not exactly great. The sound is also recorded during video recording, the maximum video resolution is 1280x720 (HD ready) According to the product page, the front camera is designed for a distance of approx. 3-10cm, the side cameras for a distance of approx. 1.5-3cm beyond that, it quickly becomes fuzzy. In cramped ducts, cable ducts, etc., this is sufficient to carry out a quick inspection and visual check, but here too the exact distance must be taken into account, because the camera systems seem to have fixed focus lens systems and are therefore set to a precise distance. At the end of the old water pipe you can see very well how quickly the image can become blurred. The somewhat rigid hose makes it extremely difficult to adjust to the correct distance in some tight situations. At larger distances, such as the cable basket or the chimney shaft, the performance of the camera system is exceeded, here you really have to examine the entire length piece by piece with the endoscope tube for the inspection. Handling the endoscope system is not easy. On the one hand, the rigid endoscope hose has to be brought to the right place, on the other hand, the control panel has to be held and operated. This is extremely difficult without a second person. Although there is a small thread on the back, it can only be used to attach a small bracket that serves as a support. The thread is too small to attach the control panel to a tripod, for example. The accessories in the form of a hook and a magnetic holder are interesting for fishing out a lost key in a gully or a screw in a drain. The camera then supports the search. Conclusion: Basically, I think the endoscope camera is good, the workmanship, the accessories and also the control panel and its operation make a very high-quality impression and definitely justify the current price of almost €129. Anyone in the private or commercial sector who is often instructed to carry out inspections in narrow areas is well served with the system. The resolution of the camera system is quite sufficient for a quick inspection or a search in the private sector. However, if you want to document damage with pictures, for example, or work in the commercial sector, you will definitely want a higher camera resolution and a further recording distance of the lens system. Despite all that, I still give it the full 5 stars
