To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Ho acquistato questo prodotto, date anche le recensioni molto favorevoli, pensando di poterlo utilizzare al posto della lavagna per le mie lezioni universitarie on-line. Nulla da dire sulla qualita' dell'immagine e sulla possibilita' di intervenire manualmente su fuoco, esposizione, luminosita', risoluzione, ecc. Non riesco pero' a scrivere sul foglio se guardo lo schermo a causa di un ritardo di 200-300ms, e questo anche alla minima risoluzione. La webcam del mio notebook Asus, stesso driver e stesso frame rate, introduce a parita' di risoluzione un ritardo di soli 100ms, del tutto accettabili. Per questa applicazione meglio rivolgersi a prodotti professionali specificatamente dedicati a questo utilizzo. Attenti anche alla presa mini USB, molto delicata.
it isn't nearly high rez enough to use as a document scanner (we wanted it for images for art portfolios).
what folks seem to use it for is to connect to a projector (not included), so a room of kids can watch the teacher's hands. of course, there are millions of ways to do that for a lot cheaper. likely you already can do this with your phone, and just need a $5 stand.
you may want to experiment if your computer can even run their software (downloads separately), but you also COULD have software (or write it!) that uses this like any web cam. all might be good enough for what you need to do. but i suggest folks test the software before purchasing or save the boxes in case you need to return it.
The product is great while it works. It's perfect for teaching classes, and was super helpful in transitioning to distance learning. Fast forward one year, and the doc cam is now broken. The issue is that the USB/power interface on the device uses micro-usb, which is notorious for breaking. The first of my issues began when the device was unable to power on when plugged in. I would have to unplug/replug the cord into the device multiple times with force to get the device to power on. My next problem arose when my computer stopped recognizing that the camera was plugged in. I would have the IPEVO plugged into my computer via USB, and the device would power on, but my computer was unable to detect that a secondary camera was active. It was at this point that I noticed the micro-usb input on the device was out of place. I tried to jiggle it back into place using the cord, but the micro-usb input ended up snapping off the device's circuit board, falling into the abyss that is the shaft of the device itself. I have no way to power the device, nor any way to hook it up to my computer. It now serves as a hideous paperweight.
If you are going to buy a doc cam, don't buy this version. Learn from my mistakes, and avoid micro-usb or anything with flimsy build quality. The newer models use a usb-c interface, which in my experience have been sturdier, so feel free to purchase the newer versions with the updated i/o.
The cable that shipped with the document camera was defective, so the document camera would not work at all out of the box. I wasted hours trying to get it to work before trying a cable of my own. Poor quality control!
