I needed an endoscope camera because I wanted to see where power cables were running under our suspended ceiling. That's when the Teslong camera came in handy.

The device from Teslong comes in a sturdy hard plastic case. The package includes the handheld with a 4.3" display, a 5 meter waterproof camera tube (with triple camera), a device stand, USB-C data cable, various attachments for the camera, a 32GB micro SD card, a mini-inbus key and a manual (incl. German language).

The camera is securely attached to the handheld, but can be removed using the mini-inbus key. The connection of the camera hose then turns out to be a USB-C cable (whether this can also be used on other devices like this, I could not check now). 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 operated via smartphone or notebook using an app (sometimes not entirely trustworthy). Depending on the Android or iOS version, you couldn't get the cameras to work at all, and handling a notebook in a tight corner isn't that easy either. Therefore, a huge plus point for the camera from Teslong.

The battery was already pre-charged and the SD card was already inserted and pre-formatted. So we could start right away. The camera hose is relatively rigid, so you can also drive through longer pipes or hard-to-reach areas. The rigidity is to my liking. In the past, the cables were relatively thin and usually snapped off and got wedged right after being inserted into a constriction or pipe.

The device itself feels good in the hand and you can act well with the device. 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 lamp (diameter of the camera housing approx. 8.5mm). Everything is clearly visible on the display and the pictures taken correspond to the display. The built-in LEDs are top and illuminate even a stock dark area well. The camera can be switched 3-fold (to the front, to the left and to the right). Thus, an area can be viewed almost 360° without turning the camera tube. In addition, there is a 2x digital zoom with 1.3x and 1.5x (although here the quality of the image, usually decreases due to the low illumination in a dark room).

The handheld also has an LED built in to get a good picture of the insertion port even in a poorly lit area.

Conclusion:
I am totally thrilled with the device and it greatly exceeds my expectations. I was able to do all the work I wanted to do with it without any problems (I found all the cables I was looking for in the ceiling). At first, the price seems a bit high, but you get a top device that is super processed delivered. Just unpack it and start looking: no more installing apps, looking for adapters for the smartphone or sitting in a tight corner or niche with a clunky notebook, thanks to the self-sufficient display. The pictures taken in HD quality are super and the endoscope is super flexible to use thanks to the 2 cameras. There is a clear purchase recommendation for home use.
