As a home inspector, my toolbox includes a variety of testing and measuring tools: screw drivers, nut drivers, framing square, concrete and wood moisture meters, temperaturehumidity meters, multi-meters, GFCI & AFCI testers, infrared and probe thermometers, binoculars and a couple of really nice digital cameras to document the appearance of the residence or structure.

Two hands required for a thermal temperature picture, one holding a digital IR thermometer directed at the object while aligning the camera with my other hand to “capture” the reading works well enough; however, a lightweight IR camera attachment to my cell phone is quicker and gives my client a true visual representation of temperature variance.

During a recent home inspection with the house temperature set at 75 and the exterior temperature 61 (picture 1), I felt a breeze several inches away from the chipped plaster above the receptacle and wanted to know more. Placing my anemometer meter at the opening, a 3 mph wind speed was recorded, the draft I felt several inches away. A wide view of the wall was provided by the K&F Concept IR camera that displayed a 9 degree wall temperature difference within 24” inch span (lack of or missing insulation). Removing the cover and receptacle (outlet), I was able to easily insert the lens for a look behind the wall. As the pictures captured, there was no insulation directly behind the receptacle box, above (bent the lens cable upward) and below using the side view camera. The red, yellow, blue, green IR picture is the outside (fiber cement siding). The exterior outlet aligns with the cold spot to the right of the interior outlet and the blue in the upper right corner is the interior outlet. I did not attempt to locate the source of the air leakage, annotating in my report further evaluation by a licensed contractor for options and cost. The nine pictures provided by the K&F Concept and IR camera provide a more comprehensive visual understanding than a mere draft from the outlet.

What is the water bottle for?
I drilled a hole on each end, passed the cable through secured with tape making a lens “stand off” for better observation looking in HVAC duct. With the rounded bottle, I’ve gone 14 feet without getting stuck.

The IR camera comes in a protective small semi-hard case, easy to use with the ability to annotate comments directly onto each picture.

The scope is lightweight and easy to use. All functions (picture, video, light, etc.) controlled by your thumb, except for the side view camera switch which is at the base of the cable. Packaged in a protective hard plastic case, with two metal latches and top and bottom foam padding cut to fit the cable, camera, USB cable and three included lens attachment options is more than adequate. A small magnet, 90 degree mirror and hook to fish wire, or “I dropped my ring in the drain” recovery tool are nice additions.

Providing two options for image transfer (one via the provided USB cable or by removing the mini SD card) gives the user flexibility.

As a home inspector, having a “third eye” is nice to answer any lingering questions regarding temperature and other issues: wall cavities, HVAC units, duct, vents, smoke chamber, chimney…

Adding the K&F Concept infrared thermal camera attachment to my tool inventory will allow more accurate reporting. Well worth the investment.

The Teslong endoscope is delivered in a practical hard case. The scope of delivery includes the device itself, a USB cable for charging and data transfer, a 32GB SD memory card, two additional tips that can be attached to the probe, one with a hook and one with a magnet, a small Allen key, the you need to remove the probe hose, a suitable spare screw, a folding stand and operating instructions in different languages. In terms of quality, the device makes a very good impression, both the case and the keys feel very high quality. The operation of the endoscope is relatively simple and after a short reading of the, unfortunately somewhat poor, operating instructions, the device can be used. The picture quality of the is not outstanding, but more than sufficient for the actual use of the device. The 5 meter long probe hose is a bit stiff, but has the advantage that it can be maneuvered and pushed through narrow pipes better. What is also quite positive is that you can dim the LEDs on the lens, so you can counteract overexposure on reflective surfaces such as stainless steel pipes. In my opinion, the supplied folding support is useless, as soon as you use the rather stiff probe cable, the support no longer offers any support and the endoscope flies around. A magnetic holder or the possibility of attaching the device to a tripod would be desirable here, as this would make the work much easier. Unfortunately, the supplied manual leaves a lot to be desired. Only the essential operation of the device is explained, but how to attach the additional tips, for example, you have to find out yourself, this is absolutely not discussed. It also explains how to remove or attach the camera probe, if you follow the instructions exactly, the device is then ready for scrap. The attachment of the probe is like a USB-C connector, which is additionally fixed with a screw, if you insert it as instructed in the instructions and then turn it clockwise until it clicks, you will break the connector, so be careful. There was probably something sloppy in the translation, because on the English pages it is described in much more detail. The built-in microphone is a nice feature for leaving any comments while working, but unfortunately it also records all the button operations, which then become noticeable as a very loud click on the video. Overall, I would describe the Teslong endoscope as quite useful, both for the do-it-yourselfer and for semi-professional use. A little more effort in translating the manual and possibly a possibility to attach the device to a tripod would be desirable. In my opinion, the price is justified.

Great product for my electrician son to use when running cables. Has a flexible endoscope cable with good rigidity that allows for good camera control. 2 camera positions, one at the very end and others on either side; all have individual LED lights. Cameras display high-quality images up close. These images can be captured by photo or video. Also records sound. A button to switch between cameras. Waterproof SD card included. Overall fit for purpose, well made and easy to use.

use this as part of my PPI (Pre-Purchase Inspection) kit. It has a great screen that is very clear. I like the ability to take pictures and videos to avoid hassles. This allowed me to look deep into areas of the car to reveal damage and mechanical issues.

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.

I've been testing the endoscope camera offered here for almost a month and I'm absolutely thrilled. I have never had such a sensational endoscope camera. I particularly liked the following properties: +Very good processing quality +Rock solid +Easy to set up +Foolproof handling +Sensational recording quality +Ultra-precise control +Great display +Perfect for tube endoscopies +Very good price/performance ratio Consequently, I can't avoid buying the endoscope camera with the Maximum score of 5 stars. I would get them again anytime!

The IPS display is bright and high-contrast enough for indoor and outdoor applications without direct sunlight. The color rendering is crisp. The usability is good and easy to understand and the display modes (both lenses, only front lens, only side lens) are easy to set and always well marked on the display. The function of rotating the images on the display is also practical. All in all, good and practical for our applications.

Easy to use and very good quality picture for what we needed it for.

Youl have hours of hot fun with this gadget.
