Teslong 5.0MP USB Auto-Focus Endoscope for Android Phone Windows MacBook

Buying this was a learning experience about this device and endoscopes in general. This scope's plusses are high resolution and automatic and close-up focus. But its lack of a wide viewing angle means having to reposition multiple times to get a view of a wide area. Its less rigid cable makes that difficult, but there's a workaround. (Update: After two years, I'm really glad I got this. I don't use it often enough to justify paying more, but every once in a while it makes an impossible job easy. My original review below talks a lot about the viewing angle, but I made it sound worse than it is. Its critical features are autofocus, which cheaper scopes don't have, and good illumination.) An endoscope seems like an attractive solution to viewing an inaccessible area. Just push it in and look around, right? Well, it's not that simple. I learned this trying to view a ceiling space through a light fixture hole using an Android tablet. The difficulties included finding a good app, placing and positioning the device, and getting a good view. I used ShenYao's USB camera Android app. It has multiple adjustments, touch zoom and pan, and respectfully unobtrusive ads. The Android app from this scope's manual couldn't find the camera. (Their Windows app worked OK.) Several "endoscope OTG" apps I tried were a morass of adware, despite 4.5+ ratings and thousands of reviews claiming "ad free". The camera's viewing angle is only about 55 degrees, creating two problems. One is that viewing something requires more exact positioning of the camera, and viewing a larger area requires repeatedly moving it. If the camera has to be pushed somewhere, the lack of rigidity in the cable makes it harder. Also, the image will be randomly rotated. A fix for all of these was to tape the camera into a cradle made from a vinyl coated wire coat hanger - see photos. It was easier to push into position, and the hook on the other end of the wire kept it level. (The camera case needs a mark at the top of the image.) The lack of wide angle also reduces the depth of field. The autofocus helps, but it takes a few seconds to focus, during which the camera has to be held steady. It shows sharp images as close as half an inch, making this a good camera for viewing and working on small objects. In dark areas, exposure is an issue. The light illuminates whatever is close to the camera. If you want to see something further off it will be dark. The apps have some brightness adjustment, but it would be helpful to find an app that could adjust the exposure by touching the desired spot. If I had to start over, I'd pay more attention to a wider viewing angle. But I might still wind up with this high resolution autofocus camera.

Been searching for this since I bought my first endoscope (another maker) which was fixed focus about 1/2 inch from the lens. Autofocus on this model works perfectly. I can examine unreachable objects from any distance. 5 MP lens gives great images. Works perfectly with my Windows laptop. Couldn't get the Google Play Teslong HD Camera app to work on my Note 9 but that was a permission issue. Couldn't grant camera permission to it no matter what I tried. Finally downloaded the apk from the site in the instruction manual and it works. USB C adapter gives a flimsy connection, probably will wrap it with tape if I use this with with my phone. This is a superior product for the price, if I ever need another I will definitely buy this brand. Note I did not try this as a borescope, no idea how useful this would be for pipe inspection but that's not what I bought it for. The cable is semi-rigid so it's much easier to maneuver in tight spaces. Yes, this is a real review. No one gave me anything or even asked me to write this review. Wayne Davis

Pleased with it, works with generic USB web cam drivers, good enough resolution, good light control. Cables a bit to stiff for me to be comfortable directly connecting to a device, but a short flexible extension takes the load of your device. Autofocus can be a pain in the ass at macro lengths.

When I first got this camera in 2019, I downloaded the OTG app and it worked great. I have used it several times and was very pleased with its function. However, the app recently updated to OTG view 2 and now it no longer works. I have eyed everything. All I can get it to do is what I the screen shots show. That's it. Nothing & "restarting camera". No other apps that I can find work either. Sketchy website... does not lead to an app to enable use of this camera! I no longer would recommend this camera!

I bought this unit after I could not find the endoscope I had purchased about a year ago. This scope is far better than the one I couldn't find, and if I do find it, it's going on Craigslist. There are two primary reasons. One - the autofocus is works very well. With my old scope, I had about a 2 inch focal length. This means that one can only see about 2 inches away with clarity, making it difficult to gain an overall view of your search area. With this endoscope, I can look at objects as far away as 15 inches and that means it's possible to see the overall scene before coming in for a closer look. For example, I was looking for a collapsed spot in a 4 inch sewer line. I was able to clearly see the entire sewer pipe as I inserted the scope, then was able to take a closeup look where the pipe had collapsed. Two - Very good image quality, much better than my old scope. I don't know what they mean by 5 MP but the resolution is more than satisfactory. I gave a three for ease of use. First, the endoscope is very stiff. I understand that it needs to be stiff to push 16 feet of scope wherever you want it to go. My old endoscope is the same way so this is not a product complaint, just noting that it can be challenging to get this to go where you want if there are curves and bends. And second, while the Android software works, you have to download an ad laden app, then apply a code so that it works without ads for this product. I would much rather see an app in the store, ready to download, without getting a third party app. For Win 10 the camera app that comes with the OS works fine although it doesn't offer many image manipulation options. I've not tried the available Windows apps since the Camera app met my needs on my Surface tablet.

I mounted this camera to my 3D printer to monitor the extrusion. I must say I am not disappointed. Even though autofocus doesn't work as well up close. It does have the option for manual focus In software. Which I am very impressed with. Image quality is top-notch. I would've liked more functional access other than focus and brightness. But other than that I have no complaints. It comes with a very long cord that is very stiff which is good if you snaking it into types of other hard-to-reach places such as pipes and access spaces. The only thing I would've changed is the ability to turn the LEDs on from the software rather than from a potentiometer on the cord next to the USB plug which is actually inconvenient.For use with a computer.

This is a tricky review to write: it depends on your frame of reference. Compared to other consumer-grade borescopes (based on my limited experience) this Teslong model is a significant step up in build quality, picture quality, and functionality: 5 stars right? On the other hand, compared to the experience I'd like and expect to have, there are several disappointments which make me want to leave 1 star. I'll split the difference at 3 stars. Here's the bad stuff: 1. [ App availability ] Although a 1st party Teslong app exists, I could not install it on my stock Android (Pixel) up-to-date phone for a long time. Apparently, something about the app made Google Play believe it was incompatible. While this was eventually resolved, it did force me to get by with different OTG photo/video apps in the meantime, most of which were total garbage full of aggressive ads and lacking basic functionality. FYI if you also cannot install the Teslong app: the least-bad of these 3P apps seemed to be "OTG View" 2. [ Reliability of phone/app connection ] If I plug this into a computer I can use it reliably with camera apps, but I want to use this on the move-- with my phone. Unfortunately, even with the Teslong app installed on my up-to-date stock Android phone, the connection between the app and the camera is highly fragile. The app seems to lose connection with the camera at random several times per minute. The app will be showing the camera image, then switch to a message that you need to connect the camera, and a few seconds later start showing the camera feed again. This is incredibly frustrating. 3. [Reliability of operation ] Sometimes after I have been using the camera for a few minutes, it will stop working and the LEDs will just flash a few times. I assume this is some kind of overheating tripwire or something similar, but it is not a great experience. Trying again later in the day it will usually be working again. 4. [ Reliability of auto-focus ] I've had trouble getting it to focus on items less than a foot away. I can see the camera is trying to focus, but often it will bring focus to some objects in the background of the frame, while the object in the foreground remains blurry. It seems to be a problem of depth or object detection. When the auto-focus does manage to focus on my foreground object, the picture can be impressively sharp.

My 4th borescope camera and the only one with a clear picture. FORGET THE OTHERS! This camera will close focus for a look at a piston and it will refocus if you are looking at distance wide spaces such as an attic! Cord is rigid allowing you to snake fish the camera. Consider ordering a soft and flexable female USB to male mini USB that fits your phone. The cord is too rigid for safe flexing at the point it plugs into your phone. The App works but is mediocre. I will look for an app that has a better interface. Forget the other borescopes. This one is what you need!

Great product! the picture quality and auto focus stand out, compared with other two popular seller amongst the top 100 in Amazon. Good enough, but would be even better if the lights are brighter.

Ultimate

A quick delivery, needed to activate the OTG feature on my cell phone to get it to work, but after that it works great, found it has a good auto focus with a good depth of field.

Out of the few endoscope I bought, this one has highest image quality. The only downside is that the diameter is large (12.5mm).

Having autofocus makes this camera actually useable unlike others that have a very limited field of view
