use an endoscope camera as a do-it-yourselfer mainly to explore hard-to-reach corners. The main area of application is the search for leaks in our caravan or other pipes. For this purpose, I once bought an endoscope camera for 200 euros, which fully serves its purpose. So of course I was curious to test what an endoscope camera that is five times as expensive can do and whether such a precious part is worthwhile for me as a hobby craftsman. The professional part is clearly better in terms of image quality and handling. It's all better lit and easier to see. The professional part scores particularly well with the color representation. The operation is very simple and you can control the camera well with the hose. The images on the display are clear and differentiated. You can record photos and videos on a memory card. However, my old endoscope camera also has this function. What the pro part has exclusively is the wifi connectivity. Images can be transferred to a smartphone using an app. This function is very useful when I want to show the images to an expert in a specialist workshop, for example. The workmanship and material quality are very good, plus there's a plus point for the robust and practical transport box. Conclusion: The significantly higher price is reflected in better image quality and more functions. The normal home user will not really need this as a rule and can therefore get by with a cheaper camera. However, if you use such an endoscope camera frequently and would like to pass the images on to third parties, you will find a high-quality tool here at a not cheap but reasonable price.
