Test the K&F Concept endoscope camera. With a cable length of approx. 5 meters, this is aimed at semi-professional users, typical areas of application would be e.g. B. examining pipes, cavities in vehicles, hard-to-reach places in shafts or, as in my case, testing a pellet silo. In terms of quality, the endoscope makes a really valuable impression, is heavy and very solidly built, even the supplied case could also be suitable for professional users. In addition to the case, the scope of delivery includes the endoscope, the probe including a 5 meter cable, a 32 GB SD card, two holders and an easy-to-understand manual. Here are the specifications as per the item description: - 4.3-inch color screen - Video resolution: 1280x720 - Photo resolution: 1920x1080 - The probe is waterproof according to IP67 standard - Probe diameter 5.5 mm - Storage of the supplied SD card: 32GB ( for photos/video recordings) - Battery storage 2600mAh (lithium battery) - The probe has 8 LED lights I've used it a few times now and can mention the following points: - The battery was almost fully charged on delivery, there is a USB -Type-C charging cable included, but no charger itself. But that's not too bad - any USB charger can be used for this. So far I haven't managed to drain the battery in my few uses, so I can't make any statement about the runtime. - The endoscope cable is a bit stiff at first, but after unwinding it can be easily bent into shape. Don't expect a 90° bend though, it's definitely too tight for that. An introduction in z. B. Empty tubing is a little tricky, the cable holds its shape but then conforms to bends when resisted. As already mentioned, some practice is necessary here. Ideally, two people should do the insertion, so one person can insert the cable and a second person then holds the screen. Since it is IP67, the cable could also be coated with a lubricant, e.g. B. soap or similar provided to reduce frictional resistance. - The lens head is a bit large with its almost 5.5 mm, here it is e.g. B. with drain openings sometimes narrow. With our sink I couldn't put my head through the drain grate, I had to remove the siphon and then put the cord through here. - The front camera is designed for a maximum distance of 10 cm, the side cameras for a maximum of 3 cm, that's enough for pipes and cavities . B. to visually check the fill level. - The LEDs in the endoscope head emit good light, even the darkest pipes are illuminated and you can clearly see the surroundings on the display. Unfortunately, the image quality when viewing the recordings on e.g. B. a PC then a bit sobering, despite Full HD for photos and HD Ready for videos. - Nice feature: the scope of delivery also includes a hook and a magnet for attaching keys, screws, etc. to fish out of pipes. Conclusion: for the required €129 you certainly don't get a bargain, but a very robust device that does its job. I can't compare it to other devices, but I'm satisfied so far. The quality of the stored images and videos could have been better, but they are still ok. I would give it 4.5 stars but then round it up to 5 stars.
