Teslong Inspection Camera, Dual Lens Borescope Camera with Light, NTS300 5" IPS Industrial Endoscope, 1080P Waterproof Flexible Mechanic Fiber Optic Snake Scope Cam for Wall Automotive Engine (16.5FT)

I bought this to chase down a plumbing leak above a kitchen ceiling, Good picture quality. The ability to adjust the LED light intensity helps this when near something white that would cause reflection back and wash out the image. I really like the side looking lense to help orient where you are and for the ease of looking in a different direction than just directly off the end of the probe.The instructions leave a lot to be desired. Didn't even say how to activate the side lense. It's a button at the base of the flexible probe.

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, temperature\humidity 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 Teslong 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 NTS300 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 Teslong NTS300 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 NTS300 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 NTS300 Teslong infrared thermal camera attachment to my tool inventory will allow more accurate reporting. Well worth the investment.

Ordered this camera last night & it was on our porch this AM. Love this thing! Stand alone no app necessary.Wow! a game changer; no more "guessing" where wires & pipes are in the walls. Don't have to worry about my husband drilling into pipes or wires anymore. The cable is semi rigid so it's easy to go up inside walls as well as down.

Kinda cheaply made but works great, nice case, easy to use. I'd recommend it

As an HVAC tech I have to say this is a money making tool. Makes heat exchanger inspections a breeze. I can easily spot failed heat exchangers and take pictures to show customers. If you’re an HVAC Technician do yourself a favor and buy 2. The only complaint I have is the camera lens isn’t very durable and scratches easy. Sticking it into a hot furnace on a daily basis also puts a toll on it. I go through about 2 lenses per heating season and always keep a back up. You will not regret having this on the truck!

Very pleased with both the quality of construction and the quality of the images produced. As a serious DIYer I appreciate high quality tools. I put this endoscope in that category. During my 40+ years of experience I have learned it is typically worth the extra money to buy quality tools designed to do a specific job. Such tools typically operate with fewer problems, produce better results, are more durable, and are a pleasure to use, instead of being a source of frustration and regret one often has when buying inferior tools.I really like most everything about this unit.- The dual camera. Being able to see straight ahead and at 90 degrees, without having to use some sort of mirror attachment, is really helpful. And being able to switch between the two views without moving the probe is invaluable (obviously can’t do that if using a mirror attachment).- The semi-rigid cable. It is flexible, yet rigid, once bent to the desired shape. It retains its shape until you change it. It doesn’t flop around like many of the less expensive units do.- The high quality image produced by the camera and screen combination. The clarity is amazing and the details you can see is impressive. The images produced have been more than adequate for any inspection that I have done.- The adjustable lights built into the probe work well. They provide sufficient light for the camera to capture a clear image. In addition, being able to reduce the intensity of the light, at times, improves the image quality. The flashlight built into the hand-held unit is handy.- The simplicity and intuitiveness of the unit operation is welcomed. Since I don’t use the unit very often, being able to take it out of the case and immediately have it up and running providing images in a matter of minutes is great. Having a unit with more “bells and whistles” but one that I would have to refer to the instruction manual, to refresh my memory on how to use it, would be a real pain. Likewise, having to depend on establishing communication with a cell phone, and the inherent challenges that can come with the software on the cell phone recognizing and communicating with the camera, etc. is not a complication I need.- The case is very nice and appropriate for a professional/industrial piece of equipment such as this.Among other inspections performed, I was able to inspect my home’s HVAC ductwork to confirm the ducts were clean and free of any mold or mildew, saving hundreds of dollars by not hiring a specialty cleaning company to clean the ducts when they really didn’t need it. I cut diametrically opposed slits in a tennis ball and pushed the probe through the slits until the end of the probe was slightly protruding from the outside of one side of the ball. Then I was able to push the probe/tennis ball through the inside of the ductwork with the tennis ball keeping the probe about 1 ½ inch (i.e. radius of the tennis ball) off the surface of the ductwork. This technique worked well and allowed a thorough inspection to be performed.
