Teslong 5mm Dual Lens Borescope Camera for Home/Automotive/Pipe/Car/Wall

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.

First I'd like to say that I'm not very good at using an endoscope. Often I'm looking at the screen thinking "what the heck is that?". Things I like: I've had several different units, and not having to mess with connecting to a phone is a great thing! No app or wrong USB connection since it just works out of the box. The screen is a good size and you can capture images or video without a problem and I just use the SD card to transfer the if needed. I've had "floppy" cabled units that require a wire or some kind of wizardry to move around. Instead this one is about as perfect stiffness as you can get (although going through multiple tight bends can be tricky). The smaller camera head is soooo much better than the earlier ones I've had that were just too big to fit through or around tight spots. The side camera is a "must have" now that I've used it. Instead of trying to bend the camera 90 degrees to try to see something, now you can focus on getting the camera to the right spot and if the forward camera isn't a great view, switch to the side camera. This was a lifesaver when I was checking the oil pump pickup in my truck going through the drain plug. I couldn't tell if there was any junk stuck in the screen with the forward camera, but the side camera showed a clear view of the screen. So the only thing I think that could be better on every unit I've owned including this one is a better way to manage orientation. I already have a hard time trying to figure out what I'm looking at, so add in the fact that maybe I'm looking at it upside down or sideways and I have no hope of figuring out what is going on. The side camera can help sometimes to figure out if the camera is pointed "up", but I think a good old yellow line on the cable indicating which way is up would be much simpler.

Works great. I dont need to use a borescope everyday but this one is good quality without spending 2 grand for a tool I only use occasionally.

I bought this for a specific project. I was surprised by how good the picture is. I have ended up using it several more times. It has made those jobs easier. It has some problems. The controls are not intuitive and the camera orientation is difficult to figure out which way you are looking. But, I like this borescope. I would definitely buy it again. I wish I had this long ago.

I was EXTREMELY impressed with the quality of this camera. I use this when doing safe/vault work, and it holds its own against the camera that is sold on locksmithing sites for upwards of $500, but I paid less that $100 for this one! I attached a few actual pictures from inside a vault lock body assembly to show the quality of the pictures!

Solved a problem with crisp clear images: I had a system with information stamped on its insides with a less than an inch clearance - was able to scoot the scope in a foot or more into that inch or less gap, then the side camera allowed me to get certainty in the contents I had to identify. Its boot up is pretty reasonable too - some other similar devices take forever.

Quite the leap forward from my first wireless borescope that requires an app and separate device. I just LOVE this camera! It meets all of my needs and then some. I'm a maintenance technician and don't have frequent enough cause to justify the "Pro" variations which cost more. The screen is glass, LEDs are bright, it has a zoom function, useful attachments, the camera is replaceable, you can order additional cameras of different lengths and different amounts of cameras from 1-3. The scope is as described and I'd gladly purchase/recommend Teslong moving forward. I included a video of my wife's hairdryer and pictures of slight mods. The label with the serial number and device details isn't very durable but that doesn't apply to the rest of the camera. Using my first camera; I found that the cable sheathing is easily torn up or gouged, so I used ¼ inch heat shrink to take the abuse instead of the camera. I would NOT shrink it, it's supposed to be a removable/replaceable barrier. The sheath almost never has to be pushed back or taken off because of tight openings. Read the instructions; if it's going to sit for anywhere near or beyond 3 months, it will be damaged unless you charge it in-between as per the instructions.

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.

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.
