5MP Auto-Focus Endoscope, Teslong 3rd Generation USB Borescope with 5.0 Megapixel Inspection Camera, 16.5ft Waterproof Semi-Rigid Cable & Adjustable Led Lights Probe for Android Phone Windows MacBook

It did the job. Used it once and on the shelf. But it will be there when I need it again

Works good. Happy with the purchase.

I didn’t know if I did, since most of the competitors were 2Mpix fixed-focus scopes. Would the auto-focus work reliably? Could I capture 5 Mpix images and videos, even with 3rd party apps? I decided to find out.The majority of scopes I saw in this price range had either USB or wireless connectivity. I’m okay with USB for its simplicity over wireless - in particular, the scope does not rely upon a battery.For my testing, I tried this scope on Android, Chrome OS, Windows, and Linux:____ Android 7.1, old HTC phone________ Teslong HD Camera / Endoscope Camera, app by Novotech________ USB Camera 9.9.1 by ShenYao____ Chrome OS 80, Acer Chromebook________ Chrome OS Camera app____ Windows 10 x64, HP laptop________ Endoscope HD Camera (download from Teslong site)________ Windows Camera app________ OBS Studio____ Mint Linux________ guvcviewI do think the 5 Mpix resolution is useful, even though my monitors are lower resolution. Positioning a scope accurately is not that easy, , and the extra resolution allows panning and zooming (without interpolation) while maintaining a sharp image on the display.The auto-focus does work well enough for the scope’s intended purpose. It’s not going to be as fast or accurate as a digital camera. The Windows Camera app also allows this scope to be focused manually – which is a nice feature when auto-focus picks the wrong subject.I was able to use this scope on all the devices mentioned previously, with all the apps listed. Capturing full (5 Mpix 2592 x 1944) still images and videos was possible, except for Chrome OS where I could not find an app that allowed changing the resolution. For all devices, the video capture frame rate was limited to 20fps.On Android with the Teslong app, the stills and videos were 3.8 Mpix (2592 x 1458). That matches my phone’s 16:9 aspect ratio instead of the camera’s native 4:3; but it crops pixels. However, the USB Camera app by ShenYao generated full 5 Mpix resolution stills and videos.Using the Camera app on Chrome OS, I was only able to capture 1920x1080 stills and 720p videos. There was no option in the settings menu of that app to change resolution.On Windows, the Teslong Endoscope HD app and Windows Camera apps work at full resolution, but see the notes section below for a quirk with the Windows Camera app. And if you want to get fancy, this Teslong camera works as a capture device in OBS Studio – I only tested 1080p projects in this case.FEATURES / PROS___ Still image capture up to 2592 x 1944___ Video capture up to 2592 x 1944 @ 20fps (with the right software)___ Auto and Manual focus___ Variable intensity ring light___ USB Video Class (UVC) device, no special drivers needed___ Waterproof___ Build quality is better than expected___ Carrying case includedCONS___ Windows and Android apps provided by Teslong need improvement in usability and stability___ USB combo plug has unproven reliability, does not fit tightly with full-size type A ports___ Camera head diameter not as small [as lower resolution options], may not be useful for some applications___ Not supported on iOS devices – you might get lucky using the Apple Ligthning to USB Camera adapter [mucho expensive] or a 3rd party version.NOTESImages captured in low light (without the LED ring light) are noticeably noisy, but expected for this class of device.Depending on the app and host device, the captured video output may be MP4, AVI, MKV, ... file format. In all cases, I was able to play back the video files without issue.In the Windows Camera app settings, I couldn't easily set the Video capture resolution for this scope. I had to switch to Still image mode, change the Still resolution back and forth, then switch back to Video mode in order to capture 1080p or 1944p video.Using Manual focus with Windows Camera app, the focus scale is inverted for this scope, but the focus slider does change the focus.Exiting the Settings menu in the Teslong Android app would hang – I had to unplug the USB cable and plug back in.If using the Endoscope Camera Windows program from Teslong’s web site, you may have to set the video compressor to MJPG, to get 20 fps rates.As reported by Linux v4l2-ctl, the maximum capture frame rate of this scope is 20 fps at 1944p, 1080p, 720p, and 480p.Holding a camera on the end of a wire steady is no easy feat. And I did get images with motion blur, due to the limited 20fps. At lower resolutions, there could have been options to capture at higher frame rates to reduce blur.DISCLOSUREI purchased this product with the help of a discount provided from Teslong. The opinions provided in this review are solely my own.

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.

The media could not be loaded. Kind of worked for about 3 minutes with two horizontal pixilation lines through it. The the whole screen view pixilated. I will exchange and hope for better. FYI - connected to a Mac laptop.

The media could not be loaded. I had an extremely cheap borescope/endoscope before that I mounted up to my 3d printer, and while the video was cool, it was low quality and out of focus due to the fixed focus distance. With this one, I mounted it, and then opened camera controller to set the focus distance and disable autofocus, and it looks fantastic. I've attached a clip to see for yourself!
