5.0 out of 5 stars OKIOCAM S2-4K: A Versatile Tool for Educators and Beyond
The OKIOCAM S2-4K is a fantastic document camera that offers exceptional value for its price. Its ability to capture high-quality images and video at resolutions up to 3264 x 2448p makes it ideal for a variety of applications, including teaching, distance learning, and design. Remember, you can do lower resolutions with no problems.Key Features and Benefits:High-Resolution Capture: The S2-4K delivers crisp, clear images and video, ensuring that every detail is captured accurately.Enhanced Low-Light Performance: Even in dimly lit environments, the camera produces vibrant colors and minimal noise.Easy-to-Use Controls: The four-button design makes it simple to adjust focus, exposure, zoom, and image orientation.Compact Design: The S2-4K's small footprint makes it easy to transport and store.Versatile Software: The accompanying teacher-specific app offers a range of features for online document sharing and live presentations.While the frame rate might not be ideal for fast-paced activities, it's more than sufficient for most educational and professional tasks. The ability to capture and share documents in real-time is a significant advantage, especially for distance learning. As an instructional designer it has allowed me to quickly scan documents in for sharing in my videos.A Game-Changer for Teachers:One of the most impressive features of the S2-4K is its ability to flip the image 180 degrees. This is a game-changer for teachers who often encounter documents that are oriented incorrectly. By simply flipping the image, instructors can ensure that their students are seeing the content correctly.Overall, the OKIOCAM S2-4K is a highly recommended document camera that offers excellent performance, versatility, and value. Its combination of high-resolution capture, easy-to-use controls, and compact design make it a valuable tool for educators, designers, and professionals alike.OKIOLABS is knows to make a variety of models, upgrades and revisions. They are a reputable company that also released updates as needed. I know many companies that just let their product go, and then features don't work correctly, and they they just come out with a new model. OKIOLABS doesn't do that.The only caveat I have is that the base, and arm are relatively light. You can place an empty coffee mug on the base and that will help alleviate the situation, but if even slightly bump the device without anything on it, it tends to tip over easily. Keep that in mind. I plan on adding hook and loop tape underneath and will just plot it down on top of it when needed.
4.0 out of 5 stars 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: 640x480, 800x600, 1024x768, 1600x1200, 3264x2448, 2048x1536, 2592x1944 16:9 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, 3264x2448@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.
5.0 out of 5 stars Nice Document Camera
This is a nice USB document camera. It is very easy to setup and use. I like the pointer styles that allows the zoom function to follow where you are pointing. The camera is very well built and is easy to fold down and store away when not in use.
5.0 out of 5 stars Tried it and like it
I had a very specific use for this and it works great.
4.0 out of 5 stars 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.
A high end tool
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.
Excellent picture quality and functionalities
The camera is easy to install and use and there are some dedicated apps to take advantage of all the features. The picture quality is very good either as a photograph or video. Dynamic range is not the best but for a sensor that size is quite good.It can be used as a regular webcam too.The arm and base is stable and easy to adjust.
Crystal Clear Document Camera for Online Teaching and Demos
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.
多機能なので面白そうなので 遊んでみたいが
OKIOLABS OKIOCAM S2-4K 書画カメラ/WEBカメラ使いこなし、使い回すと面白そう。W11でセッティングするもネットから専用ソフトをダウンロ－ドしてやっとスタ－ト。写真と動画を撮影するも動画再生で、フリ－ズ。多機能なので面白そうなので遊んでみたいが、PCとの相性が悪いのか、操作ミスをしているのか悩ましい。時間をかけて使いこなしたい。
Hefty for its size with great image quality
i got this device to assist with my soldering endeavours as even with glasses my eyesight is not acute enough at times. This has really helped now that I can enlarge reality onto a computer monitor. The coordination of hand movements to the image was a little tricky to begin with, but with practice it has come together and my output has improved.The marketed / manufactured purpose of the camera is a little different from my use case, but I imagine there are a lot of alternative uses where it would be helpful. Maybe I should start a soldering youtube channel :)Image quality is good even in low light
