needed an endoscope camera because I wanted to determine where power cables were running under our false ceiling. Teslong's camera came at just the right time. The Teslong device comes in a sturdy hard plastic case. The scope of delivery includes the handheld with a 4.3" display, a 5 meter waterproof camera hose (with triple camera), a device stand, USB-C data cable, various attachments for the camera, a 32GB micro SD card, a mini Allen key and instructions (incl. German language).The camera is securely attached to the handheld and can be removed using a mini Allen key.The connection of the camera hose then turns out to be a USB-C cable (whether this can also be connected to other devices I couldn't check whether it can be used in this way). I was immediately enthusiastic about the model, since it comes with a self-sufficient handheld. I already had various endoscope cameras. However, they always had to be controlled using an app (sometimes not very trustworthy ones). Depending on the Android or iOS version, it was not possible to get the cameras to work at all and it is also not possible to handle a notebook in a narrow corner t that simple. So a huge plus point for the Teslong camera. The battery was already pre-charged and the SD card was already inserted and pre-formatted. So it could start right away. The camera hose is relatively rigid, so you can drive through longer pipes or areas that are difficult to access. The rigidity meets my taste. In the past, cables were relatively thin and most often snapped and jammed immediately after entering a choke or duct. The device itself is comfortable to hold and easy to use. The buttons are large enough to operate the device with one hand and guide the camera with the other. During the test, I stood on a ladder under the ceiling and inserted the camera through a small opening in the ceiling light (diameter of the camera housing approx. 8.5mm). Everything is easy to see on the display and the pictures taken also correspond to what is shown on the display. The built-in LEDs are great and also illuminate a pitch-dark area well. The camera can be switched 3 times (to the front, to the left and to the right). In this way, an area can be viewed almost 360° without rotating the camera tube. There is also a 2x digital zoom with 1.3x and 1.5x (although the quality of the image decreases here, mostly due to the poor illumination in a dark room). The handheld also has an LED installed in order to get a good picture of the insertion opening even in a poorly lit area. Conclusion: I am totally enthusiastic about the device and it exceeds my expectations. I was able to do all the work I wanted to do with it with no problems (I found all the cables I was looking for in the ceiling). At the beginning the price seems a bit high, but you get a top device that is super processed. Simply unpack and start looking: no more installing apps, looking for adapters for your smartphone or sitting in a tight corner or niche with a bulky notebook, thanks to the self-sufficient display. The pictures taken in HD quality are great and the endoscope can be used very flexibly thanks to the 2 cameras. For home use, there is a clear purchase recommendation.
