JOYUSING V500-4k VGA/HDMI/USB Three Mode 13MP Docu

Best bang for the buck!
I’m sort of a budget document camera aficionado these days. I’ve used cameras from all price ranges over the years and this V508 is comparable to doccams twice the price. Like other high-end document cameras, this one can be used as a standalone unit! So cool.Pros:Picture Quality – Lots of resolutions to suit your needs. At work I have a projector capable of only 1024×768 while I need that 1080p when recording lessons on the computer. No matter the resolution I choose, this looks fantastic. I was also really pleased with the quality of the camera when using it as a web cam. Shockingly good! Auto-Exposure does a great job and you can adjust saturation/brightness/contrast to suit your situation.Standalone – To get the MOST out of this device, connect the computer through VGA (USB to use the Visualizer software), then use the VGA-Out or HDMI to connect to a projector/screen/monitor. That way you can not only use the software features, but use the camera on its own and utilize all the hardware functionality.Software – The Visualizer software is some of the best I’ve used for a document camera. The OCR scanning does a fantastic job, and I love that I can put myself in a little webcam box in the corner when recording lessons. Software comes on the CD and updates can be downloaded from the website. At the time of this writing it is version 2.1.Construction – Materials are solid enough. No creaking or groaning when being moved around. Buttons are clicky and responsive. Plus, the whole thing can be folded down to about 3.5 inches and slid under a monitor stand.Adjustments – Not only can you point the camera in pretty much any direction, but the hardware zoom and keystone settings worked great. Easy to get an image of just exactly what you’re wanting.Lights – One strip of LED lights and one single LED light. They get the job done in a darkened room, but I feel like they could be a bit brighter.Things To Improve:1. I wish the camera head could be rotated downward more. I had a specific angle I wanted to work with, but was difficult to do. I ended up adjusting the keystone settings and things worked out fine. It isn’t a big deal, and there is a workaround for my issue. Was just surprised. Could always have this sitting on a book and then I wouldn’t need to adjust anything at all. Haha2. Would also be nice to use a dome for the IR sensor. As it is, you need to point the remote sort of at the sides of the arm to get it to register a button press. If the IR sensor was built onto the base and housed in a little dome that could be pointed at from 360 degrees, that would be better!Nitpicking aside, there really isn’t anything negative to say about the V508. It is a worthy upgrade for any classroom teacher. The Visualizer software and the ability to use this WITHOUT the computer or software put this leagues ahead of the competition at the same price. I absolutely love it! Can’t wait to use it in my new classroom next year.

Great upgrade
I needed to upgrade another document camera I had. This one is sturdy, connects easily, and has all the features I need. It has worked reliably for the last 3 months. The only downside is that sometimes the autofocus can’t seem to stop trying to autofocus and does it several times in a row. Overall, it was a great purchase.

Great for Classroom
This is exactly what I needed for my classroom. I do not have a smart board and I needed something I can connect with a HDMI. The setup was very easy and the picture is crisp. Works perfectly.

Perfect picture
It has a crystal clear imaging. Plenty of options, I use with a projector for murals and various artwork imaging. Easy to use.

Habe die Kamera als Lehrkraft für mein neues Interaktives Whiteboard gekauft. Eine standardmäßige Ausstattung durch das Land/Stadt/Digitalpakt 2.0 ist nämlich leider nicht vorgesehen – wer hätte das beim deutschen Schulsystem gedacht :-)Viele preiswerte Dokumentenkameras lassen sich nur über einen Computer betreiben und benötigen dazu dann bestimmte Treiber/Programme. die auf den schulinternen Rechnern (zumindest bei uns) nicht installiert werden dürfen.So musste eine Stand-Alone-Variante her (HDMI-Anschluss), die direkt mit dem Beamer verbunden werden kann.Dies war die preiswerteste Kamera, die ich gefunden habe.Die Stand-Alone funktioniert sehr gut. Bedienung ist sehr intuitiv, Bildqualität ist sogar noch besser als bei einer doppelt so teuren Epson, die ich mal ausprobieren konnte. Autofocus funktioniert auch. Zoom auch und die Möglichkeiten, den Bildausschnitt über die Gelenke zu verstellen ist auch gut.Bisher bin ich also sehr zufrieden. Zu Langzeit-Haltbarkeit kann ich noch nichts sagen.Allgemein ist eine Dokumentenkamera eine echte Bereicherung für den Unterricht.Bisher also klare Kaufempfehlung!

Prima di acquistarlo, visto il prezzo, ho contattato il supporto tecnico per capire se poteva essere utilizzata anche come webcam. Il produttore cinese dopo alcune domande ha finalmente capito la mia esigenza dicendomi che era fattibile. Principalmente la devo utilizzare in HDMI e non USB e direi che il risultato è buono, complice un SW di bordo che attraverso comandi dati da programma Windows oppure a mezzo telecomando permettono di eseguire tutti i controlli dell’immagine ed ottenere il risultato voluto. Il limite che ho trovato è che l’output USB ha più limiti dell’HDMI e, per esempio utilizzandola come webcam non permette di ruotare l’immagine, ma si deve ruotare il braccio meccanicamente…un pò laborioso. Il supporto tecnico è premuroso fatica un pò a capire, ma è disponibile, anche se ha ammesso il limite del prodotto. Prezzo a parte, è un buon prodotto.
