Captures quality pictures with decent software
Make sure to have a small level to ensure the arm is level on both the length and width (x and z) axis. It is possible to get larger than A2, but you would have to set the camera on a box higher than the table. The thing that threw me off with the installation was that the website gave me a driver to install first, then you have to download the install files. There are 2 files to install. The images are nice and clear. There are some nice features to the scanning software, but there are some settings that I am missing. The autocrop is not as tight as I like, but it is possible to manually adjust the corners. I wish it would autorotate pages - that is, level out a slightly misaligned page. (It does take a picture sideways, but rotates it 90* properly.) The button is very nice to have. It does need a firm press. The light it provides under the arm is not so bright. I haven't really tried it in a dark room. I have a studio light to shine on my pages being captured. The camera can be used with other software, if desired. I used on Windows 11.

Horrible... See my sample photos!
Piece of crap. I'm sorry I have to give it one star. Please see my redacted photos for real-world samples. All photos came out distorted and warped. I didn't have permission to use my client's photo album, but look at all the wiggly lines at the edges and around the photos, etc. The software was supposed to remove my finger when I held the paper down. (Yes, I had that check box checked!) The camera is barely better than a crappy webcam. The software is slow, with a several-second wait after pressing the shutter button. Horrible. Horrible. Horrible. It is being returned.

Das Teil hat wirklich Charm. Leider muss es aber rechts vom Objekt stehen, um das innovative Bedinfeld gut nutzen zu können. Die mitgelieferte Software ist ebenfalls angenehm und findet das gestartete Gerät sofort. Leider darf man das OCR-Programm der Firma hier nicht nutzen. Meiner Meinung nach hört der textbasierte Einsatz aber bei A4 auf. Aber ich habe auch nicht langegenug herumprobeiert. Mein Einsatzgebiet ist der Bereich von hobhgradiger Sehbehinderung: Als elektronische Lupe für den PC ist das Teil wirklich beeindruckend klein. Aber der Transportabilitätsaspekt ist stationer doch ein Nachteil: Als Kamera direkt am TV - wäre auch Reizvoll. Ich werde aber jetzt ein weniger mobiles Gerät testen, das sich hoffentlich mit meinem Programm "Zoomtext" ocer "Fusion" verträgt. Es wäre eine wirklich kostengünstige Lösung gewesen.
