OKIOLABS OKIOCAM T-4K A3 Visualiser 8-mp for Teaching, Classroom, Distance Learning, Real-Time Projection, Video Recording, for Zoom, Meet, Skype - Windows, Mac, Chromebook

Fantastic buy used it straight away for my online tuition, ony if it had a soft case to fold it in after use it would be perfect

I have been using this for a while now, it is so easy to carry with me and also very clear images! Only thing is it’s super bright on white paper, which can be easily be adjusted using the brightness.I use it on Mac, can take little while to come, not sure why this is. I have found that connecting it 5mins before using helps a little.

It probably cost very little to produce. It’s a bit wobbly and cheap but so long as you don’t pay a silly amount for it, then it does the job adequately and it’s simple to use and set-up.

Great product - very compact, easy to use and has been a great help for my teaching. If I had to criticise, the build quality is not exactly premium, but it's the functionality I care about and it works great.

Overall poor product, with mediocre software support.The image quality taken in daylight is passable but you'll find quite often your having to retake the picture again to get an acceptable image (for example document scanning) anything less then bright daylight the image is too grainy to work with so if your using it to scan documents i cant rely on it.Its basically a cheap webcam stuck to a cheap plastic stand which wobbles making taking images even more difficult.Some may get better use out of it as it has other feature but if your buying it to bulk scan documents or pages in book avoid, even a basic smart phone running android has app thats do a far superior job with far more ease.

I am a teacher so started live lessons this week- this visualiser has been very easy to use and has saved my maths lessons from home! I have a MacBook and literally just plugged it in, downloaded a programme from the website and it worked. Was able to connect during my Teams meeting and use the visualiser without issue. Very pleased with it, simple to use and it works!

Easy to adjust, nice and clear. No problem seeing A3 clearly. Plus and play easily recognised by zoom and OBS. Well worth the money. Very portable too!

The reflected light from the paper seems to glare off of paper even when light levels are relatively dim and looks so bright that you can't read writing with a ball point pen. This does not happen with the camera on my phone. I'm not sure why this is but it can't easily be adjusted by turning down brightness in my camera app on my laptop.It is a high quality camera and is great for everything except online teaching unless you want to sit in a pretty dark room or can write in thick felt tip which limits how much you can fit on the screen. It's made working from my conservatory during the day much more difficult even though I've blocked out light from most of the nearest windows and there's no direct sunlight. It is also January so it's not particularly bright and it becomes a problem starting at around 9:00AM.

Great for my online art classes, easy to use for demonstrations. Good picture quality

Ive been using it for long tume its very useful for my teaching art online

Contento con la compra. Cumple su función.

Je l'utilise pour faire des master-classes et je ne suis pas déçu du tout. Le focus se fait parfaitement et simplement même lorsque que je filme un papier puis un écran.
