Your Turn: The ELMO HV-110U Document Camera

Posted by wrmcnutt on April 30, 2010

Some of ya’ll might remember a bit of old tech called an “opaque projector.”  This was a monstrous piece of hardware about two feet tall, two feet wide, and three feet long.  It had an complex and expensive set of optics that allowed you to put a book or other printed material on it’s target platform, and it would project an image of it on the screen.  It took a lot of lumens to project that image, so the thing ran hot, consumed a lot of power, and ate expensive bulbs like they were popcorn.  Accurate milling of lenses is an expensive, labor-intensive process, so this was also a very pricey way to heat up your classroom.

While you can still find opaque projectors today, mostly marketed to artists, they have largely been replaced by the document camera.  This is a specialized video camera with a short focal length that is suspended over the book or other material the instructor wants to project onto the screen.   With far smaller optics, it runs cooler, takes up far less space, and in general is handier than the old opaque projector.  The problem is, they cost about the same as opaque projectors used to.  In general, they start at around $1200.00 and go up from there.  Without a lot of effort, you can spend $5000.00 on a document camera.

Well, I’ve found one for under $800.00.   It’s called the ELMO HV-110U.  As you can imagine, I’m skeptical of the quality of the image that’s going to come out of a camera that’s this cheap, and to make things worse, the only two reviews I’ve found are quite negative.  But that’s only a couple of guys’ opinions.  I thought before I make a commitment to this piece of hardware one way or another, I’d ask you guys.  Have any of you worked with this particular document camera?

    The Elmo HV-110U has been discontinued and replaced by the new MO-1. The MO-1 is smaller and even more compact than the HV-110U was. With the new MO-1 you get 720p picture quality, 8X digital zoom, video and audio recording capability plus HDMI and VGA connectivity. Price? Under $400. Check it out:
