The name Teslong has stood for quality and functionality in endoscope cameras for years. This three-lens camera, model GW45.0001, is no exception. In contrast to the cheaper endoscope cameras from Teslong, this camera is housed in a hard case and can be permanently protected and taken anywhere. Thanks to the supplied 32GB micro SD card, I can put the endoscope into operation straight away. The 2600mAh battery is also pre-charged and enables wireless operation. If the battery runs out, operation can be continued with a power bank. Thanks to the good operating instructions, I quickly became familiar with the functions. The device can be operated comfortably with German menu guidance. The areas of application are diverse. Water protection allows penetration into areas filled with water. So you can easily explore blocked pipes and get three different scenarios (straight ahead, left, right) of a situation through the three lenses. The integrated light on the probe moves with you when you change the camera and enables noise-free resolution for sharp photos or video recordings. The light can also be dimmed if required. The date and time are integrated into the medium for both functions. It is possible to view or delete the recordings on the control unit at any time. The panel has a microphone that records the sound during the video function. This way you can take notes during the inspection. The probe head measures almost 5.5mm. This means that the camera can easily get through pipes and winds its way through the engine compartment or through pipe routes in the wall with a 5 meter cable. What I might be missing on this unit would be a magnetic mount and a 1/4 inch thread for a tripod so I can fix the panel when running the 5 meter hose. Sometimes 2 hands are needed and then you look for a safe place to put the control panel, where you can also keep an eye on the screen. The screwable folding stand is not always helpful. If a 1/4 inch tripod thread would be used for the stand, you would have killed two birds with one stone. The accessories are very useful with this model. A hook or magnet can be attached to the probe. With these two helpers it is possible to fish small parts out of pipes. If I had had this achievement three weeks ago, I would not have had to unscrew the sink siphon to get a piece of jewelry. If the piece of jewelery had already ended up in the wall pipe, I would never have gotten it out without the hook. It may even be possible to solve blockages in the pipe with these attachments. With these two accessories, Teslong has thought along wonderfully.
