G4K Autofocus Usb Camera Module Dual Microphone Webcam,Ultra HD 2160p 30fps Web Camera Module with Dual Audio,IMX415 Webcamera Module with 100 Degree No Distortion Lens for Windows,Mac,Raspberry pi

So we managed to get a whole collection of these and i must say each one is different to the next one. We have the G1000fps, G4k Autofocus, G4k UHD, G webcamera and the G Global shutter. Using a rasp Pi you can make these work wonders. I didn't think i would be so into the science of photography but, using these has introduce that to me. They were fairly simple to get up and running and doesnt take to long. The G4k autofocus is probably the one i use the most for cropping purposes.

This web cam was easy to set up, attaching it to an iMac system (ultimately it’s going on one of our Raspberry Pi 4s, but for testing purposes I set this up with my iMac). I followed the instructions in the little supplied instruction booklet for using this with QuickTime, and it connected without issue.The image quality is really very good, with clear, crisp image and true to life colours (as long as there isn’t light coming in through a window directly in front of this, which messes with the saturation).The camera module comes with a lens cap, and has a 1m USB cable. The module is designed to be mounted into a device, but doesn’t come with any fixingsOne thing I didn’t like about this is that the cable smells quite bad. Not normally something I’m conscious of in electronics devices, but this has quite an acrid, chemical smell to it that lingers on hands where they’ve been in contact with it. Hopefully this will dissipate over time.

The picture quality is surely good but I honestly had similar results with top level webcams from major brands that are already protected in a case and possibly with better after-sale support. Audio is also really good but at £90 I feel that it is a bit too expensive

By the time this arrived for review the product was marked "Currently unavailable" so I'll keep this brief.This is a UVC-compliant plug and play webcam with autofocus. It is delivered in a small box with a set of Windows-specific instructions. I don't use Windows but tried it on both a Mac and Raspberry Pi, both of which it should work on.And it does.On Rasbian it is reported by libcamera-jpeg --list-cameras as a "4K USB Camera: 4K USB Camera [3840x2160]", offering 10 different resolutions ranging from 320x240 to 3840x2160. Using fswebcam I was able to take images at the stated resolutions. Autofocus worked well. Images were quite markedly overexposed and would need post-processing to be acceptable. In addition, and more seriously, there were image artefacts, with lines across parts of the image, or heavily pixelated areas. These could not be easily corrected.On a Mac I managed to take images and videos using - respectively - Photobooth and Quicktime. By default the former were 720x480, poorly exposed (overexposed again, probably by 1+ stops) but well focused. Quicktime movies were also overexposed, though perhaps by only 1 stop, but focus was again good. QT movies were 1280x720 and H.264 encoded.It also worked with Zoom on a Mac. Depedning upon your Zoom setup the field of view of the lens might be too wide. It is significantly wider than the integral webcam in a Mac laptop or desktop monitor, and wider also than my current webcam. To give a better proportioned 'head shot' you have to sit uncomfortably close to the camera.At the offered price of £89 this is not good value for money due to the image artefacts and overexposure. The autofocus is pretty quick and works quite well, but doesn't make up for the other shortcomings of the camera. The absence of any detailed instructions for platforms other than Windows (there is some Mac troubleshooting info for mirrored images etc) loses it a star, as does the image defects and the overexposure.I'm going to try and manually tweak the image quality and exposure using libcamera on the Raspberry Pi and will report back if I end up with something more usable.

I ordered this 4k camera module along with 2 other module cameras for use on my 3D printers running Octoprint from a Raspberry Pi4b, unfortunately these module are larger than I had thought so they don't fit into the PiCam mounts so I need to design and print new mounts for them. For testing purposes I have used this on my MacBook Pro.On opening, this camera comes as a module so it will require some sort of case for prolonged use. The board and lens look to be of a very high quality and a lens cap is included along with a USB2 power cable fitted with a USB-A connector at one end and a four pin JST connector at the camera end.I found that the lens itself can be turned but this only seemed to throw everything out of focus so keeping it as it comes seems to be best which works with the autofocus very well.After connecting this to my MacBook and handling the module carefully I tested distance and macro images, the different distances all worked perfectly with the autofocus until I got down to below 6cm at which time the camera couldn't focus properly. The photo I captured of an ornament shows a good deal of detail and was taken at a distance of 20cm. I think with some decent software this camera will be much better than just using the basic MacBook programs however it was still surprisingly good and worked straight away without requiring further drivers.The one downside to this unit is that the instructions are very lacking and seem to be written for the whole range of modules so there is no detailed information on settings or operation.Once I have sorted out a mount for this I will be fitting it to one of my 3D printers as the picture quality is far better than that of the PiCam, as it will be fitted to an RPi4 it might require drivers which I will need to source if necessary.This camera could have many uses out of the box and with the 4k image quality it will make a very good video or stills camera but not really for macro use.At the time of this review it is listed as unavailable so I don't know the price therefore I can't comment on the value for money although I don't see this being a cheap option due to the high quality.Terrific camera module.Recommended.
