NTS500B Dual Lens

After using this tool on multiple occasions I would highly recommend it to anyone needing to look into or retrieve items from narrow spaces. The diameter of this camera is very small and that helps in reach into areas that others would not be able to. The description says the camera is 5.5mm in diameter. I actually measured the diameter to be closer to 5.75mm with a micrometer but if the bezel that is threaded onto the end is removed then the width is only about 5mm. I got this camera to help me get a look inside the wall of my bathroom where there was water damage. Then when I didn't find anything leaking in the wall I used in to look inside the drain pipe of the shower and was able to see signs of water seeping in through the weep holes from the mortar bed under the tile floor which suggested the problem was water in the floor and that turned out to be the case. Later the water stopped coming out of the shower head. I eventually figured out the problem was with the shower hose and used the camera to verify that the lining of the hose was breaking down and causing the hose to get clogged. Most recently I was replacing my car battery and accidentally dropped a nut into a hidden area under the battery holder. The wire to the camera is flexible and will also to some extent hold its shape after bending it so I used that to make it a bit more curved at the end and was able to insert it under the battery holder through a narrow gap, see the nut there, and then with the magnet attachment I was able to retrieve it. The magnet is very small but was strong enough to hold on to the nut very securely while I pulled it out. Since there is both a forward-looking and side-looking camera I haven't used the right angle mirror yet but the hook attachment would be handy for retrieving things that the magnet cannot. I like that this camera comes with its own display rather than relying on phone software that may become obsolete over time. For the price and size I've been very impressed by the image quality and and the light illuminates the subject well.

This is a quality endoscope, I originally purchased to run in duct work to see if there were any leaks or openings. Didn't work that great for that as the further you insert the cable, the more control you lose. You can kind of turn the cable but it doesn't work that well when more than 3 feet of cable is extended. I did also use to check under my deck to see if there were any entry places in the house foundation to see any way for mice to gain entry. Also inside to see any evidence of rodents. Also used inside of ductwork to clean with a shop vac. You can insert the scope and also the shop vac end to make sure you get all the dirt you can see instead of just blindly vacuuming . I am planning on using to see in hard to reach places on my pickup frame so I can more precisely coat with oil to stop rust. It really is handy, there are more uses than you think. One recommendation for the buyer I ordered the 16.5 foot model, as mentioned, I don't see any way I would accurately use all 16.5 feet of the cable It just is not controllable when you push that much cable into whatever, So now I have a looped up cable that is always there, I may use some day but I am not sure for what, consider a shorter cable. The picture quality is very good, the light and the smallness of the camera end is very good, I would not go bigger, it will limit what you can use it for. The side light is good, but then again, you can't really turn the cable and side light where you want after 3 feet or so. I really do like the product, and highly recommend, The extra cable length ad lack of control are only minor inconveniences.

Let me start by saying that I'm impressed with the quality of this borescope and it has proven to be very useful. In particular, the small diameter (5mm) has allowed me to use it in really tight spaces with limited access. I wish I'd bought one long ago. It's easy to use, works as decribed, is very well packaged and I'm happy with it. That said, there are a couple of things I've learned from using it. These aren't complaints, just observations: - The 16' snake is much longer than I've needed so far and the stiff coil can be unwieldy to work with. I could easily get by with a 4-6' snake most of the time and will check with Teslong to see if a shorter snake is available. Changing it requires unscrewing it from the monitor, but it would be a rare occurrence so it shouldn't be an issue. - If you need to need to rotate the snake for a different view or to get past an obstacle, it can be difficult because it's rigidly attached to the monitor (plus you may have the coiled extra snake length to deal with). The side camera helps sometimes, but it's only a partial solution. With this experience under my belt, I would love to have a shorter borescope with a flexible head controlled by a joystick, but that's not what I paid for and I can't justify the higher price for my limited use. Again, I have no complaints with this product and I'm glad I have it.

I am an industrial maintenence technician and recently had need for boroscope. This teslong was the perfect solution. It has excellent photo and video quality for the price and it's easy to understand and operate. The only reason I gave it 4 stars is; no matter what I do, I can not get any photos or videos off the device. I've tried USB-C to USB-C to android, to apple, to a PC, I've tried USB to USB-C to a PC, I've tried an SD card reader, I've tried a new SD card, every time I either connect the boroscope to an external device, or remove the SD card, the photos are corrupted / deleted (they disappear from the SD card). This could be me not understanding technology, or it could be a faulty boroscope (?), but if getting the photos off the device isn't an issue for you, (and it's not an issue for me), this is a great boroscope to have.

Camera is high quality. I work in a dealership and I use this borescope camera for cylinder inspection and other parts inspection. I recommended my coworkers this product. So far 5 of them purchased it after borrowing this product from me.

Great scope. The value is unmatched (keep an eye on price, it can vary wildly). However, there are a few things not obvious in the ad that you should know… First, the cameras capture 1080p but the display is only capable of showing you 720p. Videos saved to review later (on a different device) will be much nicer than what you will ever see live on the included screen. Second, the scope uses a USB-C ish connector. I say -ish because you can’t plug the scope into any other device and expect it to work like a camera. A normal USB-C port won’t even power it. Windows Camera app does not detect it. Also, the connector is noteworthy because the similarly-named NTS500 uses a different connector. So Teslong’s range of accessories for the NTS500 do NOT fit the NTS500B! I believe an adapter is available directly from China but I have not seen it for sale domestically. My third, and biggest, complaint is that Teslong locked the display unit down so that you can’t plug it into a laptop to see 1080p video live. Connecting it simply charges the battery. If you put it in file transfer mode, connecting it is like connecting an SD card or thumb drive. You can see files, but the display on the unit locks out preventing you from recording anything while it’s connected. So that’s a bit of a bummer. None the less, it’s a great unit at a reasonable price. It comes in a perfect case. The battery lasts a long time and it can be used while it’s plugged in to charge. I’ve used it on some rough jobs and it stands up very well.

Very convenient and easy to use. I used it to help fish cat5 inside the walls. The semi ridgid camera cable needs some getting used to. Picture quality is very good and sharp at about 3-5 cm from the camera (remember it is fixed focus lens) and the Led lights is bright. The second camera was super easy to flip over to at a press of a button. The tool was ready to work right away, with a fully charged battery and included tf card. This was well worth the price to get something with better quality and a bigger and higher resolution screen

Clear picture i use it to scope engines. Side camera is awesome for checking condition of liners

Le produit est très bien fait avec de très bon produit de qualité.
