OKIOCAM S2-4K Ultra HD 8MP USB Document Camera for Teachers & Classrooms with OKIOPoint AI-Tracking, Capture Near-Ledger Size, Great in Low Light, Support Mac, USB-C iPad, Interactive Display

Love this!! This was exactly what I was looking for and works great!! No problems. Easy to use and projects a clear, fantastic image.

This is a small document cam with weighted base. It is basically a nice webcam on a pivoting/extending arm. It has a few built-in controls for exposure, zoom, flip, and auto-focus.== Build ==The unit feels substantial out of the box, but all the weight is in the base. It's about 430g (15.2oz) total. It packs pretty small, but I don't like how the cable exits the top of the cam module. The base, and first section of the arm are very stout. After that things get a bit flimsier. You can't really touch the arm during use without it wobbling.== Webcam features ==This is a USB 2.0 webcam. It has 4 buttons.Sun: cycles through exposure/brightness, 6 levels.Magnifying glass: Zooms 5 levels.Outline: re-focus.The side button flips the image. Supposedly it does a single auto focus in document mode, but I haven't figured out what document mode is.The webcam image modes are primarily MJPEG. It has 4:3, and 16:9 aspect ratios. These all support 30 or 25 FPS.4:3 resolutions: 640x480, 800x600, 1024x768, 1600x1200, 3264x2448, 2048x1536, 2592x194416:9 resolutions: 1280x720, 1920x1080, 3264x1840Additionally, it does have an uncompressed/YUYV mode with more limited resolutions, and much lower framerates at high resolutions. They are 640x480@30, 800x600@25, 1024x768@15, 1280x720@10, 1600x1200@5, 1920x1080@5, [email protected] webcam exposes a number of software controls. There are the standard brightness, contrast, saturation, hue, and gamma sliders. There are toggles for automatic white balance, and continuous auto focus. Then there are controls for white balance temp, sharpness, backlight compensation, and absolute focus.The microphone is usable for voice, but it does have some low level noise (hiss and crackle).Okiocam appears to release firmware updates for their products, but there aren't any for this new model yet.The webcam chip is SunplusIT SPCA2680A 4K2K/8M USB 2.0 Web Camera controller. Seems to fit the bill. Dunno about the sensor.== Apps ==The live presentation software is available on Win, Mac, Chrome (extension), and iOS. It is necessary for the Okiopoint QR tool to work. Depending on the computer it can be a little slow at following the QR code, but it is functional enough. It has the ability to overlay a second webcam which worked on Win/Mac, but I could not get it to work in the Chrome version. Otherwise it lets you zoom the camera fluidly, pan around, freeze the image, rotate, mirror, and draw on top of the image. Simple enough, but full of features. The native apps (Win/Mac) seem to expose some extra controls like exposure, and re-focus without touching the physical buttons.While the main Live app is mostly for presentations, there's also a surprising amount of other webcam tools available from Okiolabs. Such as snapshot and recorder, time-lapse, stop-motion, and separate camera control apps. I played with the time-lapse and stop-motion. They seem a little less polished, but they work, and could let you do some neat videos.It seems like it would make a reasonable book/document scanner, but no software for this is provided. I played with it a little bit on Linux with capturing some images, and running pdfsandwich. Initial results make it seem feasible, but requires more tuning than I want to do right now. I tried CamScanner on Windows, and it can do a basic job, but did not embed OCR'd text.

Setup is a snap. Free software. Works perfect for remote math tutoring. Much easier than using a touch screen with stylus. Just what I needed.

This is a great item. I was able to use it right out of the box. Installation was super easy. I would buy again and consider other items form this company.

The camera has good resolution. Very convenient to use, easy to handle.

setup was a headache and not well explained in the instructions . there's no power indicator, so you can't easily tell if the camera is on or if it's malfunctioning. I had to search online to discover that there’s no LED to show the camera’s status. it also doesn’t work with linux unless you use a virtual machine. there’s no clear signal when a photo is taken, which is inconvenient. the quality of photos is decent, but the user experience is lacking. the included QR code stick is puzzling until you figure out what it does

I was interested in this strange camera projector because it can be hard for me photograph documents with my smartphone.My environment doesn't have the right lighting and my smartphone doesn't do well with low lighting conditions.So I thought this camera would be a happy medium between a traditional photo-scanner printer and a digital camera.Unfortunately, it didn't quite measure up to my expectations.The privacy disclaimer included with the product was strange and got stranger when I went to download the tie-in app. The user agreement mentioned that I would still have to take certain precautions from having my documents seen by other parties when using the camera.As near as I could tell from all the legal-ese, it meant that whatever I was broadcasting could be intercepted by another party, like remote-viewing.I wasn't too happy with that, so I opted not to use the app.You can still kinda scan documents with the camera and have them appear on-screen on your desktop, but the picture quality is kinda mediocre.And for the price you're paying (about $90 when I acquired it), I feel like that's too many pitfalls to use this product in any serious capacity.I can't recommend this.3 stars.

I should start by saying I'm a pretty critical reviewer, and this would easily get 5 stars for me if they ditched the smart-pointer or implemented it differently. The smartpointer is literally a QR code on a stick. If you're in love with it and you lose yours, just print a copy of the QR code form the images and tape it to a pencil. Tah dah! You have another matchbox with a QR code on it shoved on a wooden stick...I mean you have another smartpointer.If you're going to take the time to try and implement something like this, make it gesture based and have the software look for and track any old writing utensil. This wouldn't even be hard since the utensil shaped object would be the only thing like it in motion in the frame. You could even track it over a box of pens and pencils since those would be static and ignored by the motion tracking system.Sorry for the rant. That's the only reason I took a star off. The doc camera itself is FANTASTIC. You know how ELMO doc cameras have always been pricey but good at consistent light levels, autofocus, and crisp pictures? If you hid the cable to make it look just little more polished and slapped an elmo logo on the side, I wouldn't even think twice about this being an elmo cam. It's that good. The software is pretty good too, to the extent that I'm going to see if it locks to their hardware IDs or if I can use it with a few other cameras I have too.
