The PS751 Desktop Document Camera from Lumens allows you to image documents, transparencies, and even 3D objects for presentations and classrooms. The camera can capture up to 1080p video at 30 frames per second, and features 8x optical zoom, with an additional 2x boost from sensor zoom. It provides dual LED side lights for main illumination, which are mounted on adjustable gooseneck arms to help minimize glare. For X-rays and transparencies, there is a backlit surface as well.
The PS751 can be connected to a computer using USB for use with annotation software, or can operate standalone - you just need to plug in a projector or display. It features an HDMI output, two VGA outputs, and a composite output to cover all of your bases. In case you need to view content from a computer at the same time, it features one HDMI and one VGA pass-through input.

Captures at 30 Fps
A 30 fps native frame rate means the PS751 is suitable for capturing moving as well as static objects. 30 fps is the standard frame rate of progressive scan, NTSC video, and will not exhibit the kind of motion blur and choppiness that becomes apparent at slower frame rates
8x Optical / 2x Sensor Zoom
The camera features an 8x optical zoom lens with an additional 2x boost provide by "sensor zoom". Sensor zoom takes advantage of the fact the sensor resolution is higher than the output resolution, and uses these extra pixels to increase magnification without significant quality reduction, unlike digital zoom, which merely up-scales the image. The camera also feature 12x digital zoom
Larger Than A3 Work Surface
With the camera fully extended, and set to the widest zoom setting, the lens covers a working area of 20.4 by 15"

In addition, HDMI and VGA pass-through inputs allow the camera to act as a presentation switcher. For example, you can switch between a PowerPoint presentation on your computer a document being recorded by the camera without needing any additional hardware
LED Illumination on Adjustable Goosenecks
The direction of illumination from the dual LED side lights can be adjusted to help minimize the appearance of unwanted reflections of glare
One-Press Image Optimization
