Document Camera Shopping
Document camera shopping can be challenging. The terminology used is often overly technical. What is worse is that many companies focus on specifications that may or may not be in your best interest. For example, it is common to see the megapixels of the sensor of a document camera highlighted first and foremost. The dirty little secret is that the sensor is only as good as the resolution. This is the reason why your cellphone camera with 10 megapixels may not look better than the image on your document camera with 5 megapixels. A megapixel is one million pixels. A resolution defines how many pixels are shown on screen at a time. For example, a camera with the VGA resolution of 640 x 480 can display 307,200 pixels. That is about one-third of one megapixel. Therefore, having a 2 megapixel sensor on a camera with VGA resolution is going to result in poorer image than you might expect.
Document Camera Shopping at HoverCam
The HoverCam Neo 3 document camera has a 2 megapixel sensor. This may not sound impressive but the Neo 3 allows for UXGA image resolution. That is 1600 x 1200, or 1,920,000 pixels (almost 2 million). What is this means is that the Neo 3 actually utilizes its entire sensor to give you the best possible image.
When document camera shopping be sure to check more than simply the megapixels. It is not always the best indicator.
