A document camera is a simple yet effective tool for presenting any type of material, whether it’s a document, a book, a 3D object or even when doing a demonstration. There are a lot of options when it comes to selecting the right one for you. So how do you know you’re making the right choice? Let’s explore the top features that document cameras have to offer and find out what is important for your unique presentation setting.
Resolution is the measure of the size of an image or video and is measured in pixels. The more pixels you have available, the sharper the final product and the better the overall quality. A 1080p Full HD resolution (1920×1080) document camera is the standard for everyday classroom use. For even better clarity you can upgrade to a 4K Ultra HD resolution (3840×2160) model. 4K Ultra HD has four times the number of pixels as 1080p Full HD and provides for the ultimate viewing experience.
What is zoom and why is it important? Zoom allows you to enlarge or magnify a document or object without moving the camera. Optical zoom uses a series of individual lenses and a mechanical process to enlarge a subject without loss of quality. Sensor zoom digitally enlarges the subject while maintaining the original resolution. Digital zoom gets in extra close on small details by scaling to the resolution of the original, but you may lose some clarity in the process. A camera with a high zoom ratio is perfect for viewing small text and tiny objects.
HDMI, RGB, USB: does the camera have all the proper connections to interface with your computer, projector, monitor or interactive panel? For remote and hybrid teaching a USB connection is key. The camera should be compatible with Windows, MacOS, and Chrome. You’ll also want a camera that can double as a webcam for the most flexibility. More advanced document cameras can even connect to the web to allow for direct access to content or to use educational apps.
Want to live in a world with less wires? Wireless casting technology is perfect for classrooms where flexibility is needed. You will not need any cables to stream your document camera to your capable projector or interactive display. The simple and secure wireless connection via casting is perfect for small to medium sized classrooms.
A camera with a built-in battery means you can move your camera around and never be tethered to a single workspace. Batteries often appear in document cameras that feature wireless casting. A built-in battery and wireless casting make moving your document camera around the classroom for limitless, unique learning opportunities.
Do you have to move the document camera from classroom to classroom or classroom to home? A small, compact document camera is great when you can simply fold it up and easily transport it in your everyday bag. No need for special cases or additional packages. Portable document cameras make it easy to present from a variety of teaching locations.
Having the ability to add on some extras can play a large part in your decision. Use a microscope for your lessons? A document camera with a microscope adapter lens will help you get the most out of both items. Use ad hoc written ideas during the day? A document camera with a dry erase writing board option will save paper resources and create.
