Love this product!
This product is perfect for what I was looking for. Great quality for the price and stores small and compact. Many settings to adjust focus and lighting and the “wand” to zoom in and out is so cool! Highly recommend!

Compact document cam. Packs down for portability. Well designed software.
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: 640×480, 800×600, 1024×768, 1600×1200, 3264×2448, 2048×1536, 2592×1944 16:9 resolutions: 1280×720, 1920×1080, 3264x1840Additionally, it does have an uncompressed/YUYV mode with more limited resolutions, and much lower framerates at high resolutions. They are 640×480@30, 800×600@25, 1024×768@15, 1280×720@10, 1600×1200@5, 1920×1080@5, 3264×2448@1.The 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.

FANTASTIC document camera. Gimmicky “smart”pointer.
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.

I am unsure as to who the target audience of this item is. It is a supremely expensive document visualiser. As expected for the price, this tool is easy to setup, delivering a brilliant qualiity of picture at crisp 4k resolution. I was amazed by the stark similarity in quality between this and my logitech Brio webcam – the difference between the two is that the Okio has some issues with exposure, although this doesn’t show up during intended use. Overall, this is a brilliant piece of tech for someone who is to use a visualiser on a daily basis.

This document visualiser is fantastic for remote teaching and presentations. The 8MP camera delivers crystal clear images, and the 4K resolution makes it perfect for showing detailed documents or items on a large screen. Setup was simple, and it works seamlessly with both my Mac and Chromebook. The included OKIOPoint software adds useful annotation features, and the smart pointer is a nice touch for guiding students during online lessons. It’s lightweight, compact, and folds away easily when not in use. Definitely a great tool for anyone doing web demos or educational work.

I needed a visualizer especially for my online meetings and presentations because it has a 4K resolution, the quality that it provides is outstanding, the image is clear and sharp and it makes a difference when I am sharing documents or doing live demonstrations. The details that this visualizer can pick or clear so it is easy for my colleagues to see exactly what I’m showing and this has significantly improved the quality of my presentations. I find the setup process to be quick and easy and the great part is that it is compatible with all the devices that I’m using, I personally have a Macbook but at work I have a Chromebook and I didn’t have any issues so far to connect this visualizer. The camera`s arm is adjustable and this allows me to position it exactly what I have to and because it is compact when folded down, it is easy to store it in my bag especially when I’m traveling to work. I can simply use it without having to install any software because I just plugged the USB port into my laptop and then I start the camera app which is straight from windows and I can already see the image which is great. This is an effective tool that has made my online presentations way better, limit quality is great and it is also very easy to use.
