Commonly known as doc cams and visualizers, the document cameras have higher resolution than any overhead projector. Some models, such as the Joyusing camera, have Ultra-High Definition (UHD). That allows for a clearer image even when displaying magnified texts and objects.
The document cameras are extremely portable. This is a big difference from the overhead projectors, which are attached to the ceiling. These cameras can be mounted on a stand or a table. Of course, some of them can be used just like an overhead projector, although that’s less common.
However, much like the projector, you can project things on the screen just by placing the different objects or documents under the document camera.
That’s why document cameras have become a very basic tool in any classroom. The traditional overhead projectors used t now they are a thing of the past. However, here are 2 important questions: Which one is better? And why?
Document Cameras vs Overhead Projectors
A document camera can be compared to an upward projector. However, these cameras are the following innovative jump from the attempted, tried, and genuine overhead projectors that everybody knows. That leads to the question of “why do the switch?”
A document camera gives much greater flexibility. An upward projector is an extremely cunning, yet basic, apparatus once you see how it functions. The light is projected through an upward sheet. Then it bounces off a mirror and onto a divider or screen.
The unfortunate constraint here is that upward sheets must be utilized. That doesn’t take into account rapidly showing a picture that might not have been a piece of the illustration plan, sharing pictures of 3D items, or carefully teaming up with digital collaborators.
Drawing on an upward projector sheet can be an untidy undertaking as the pen smirches and spreads. With a document camera, however, clients can use a software program to draw in. Then, at any point, they can effectively delete their drawings or add to them on a case-by-case basis. The smeared pen isn’t left behind.
The size and transportability are other significant distinctions. Overhead projectors are weighty and massive. They are commonly sat on a table or wheeled around. A document camera doesn’t have that problem. It can be easily moved to another area.
Document Cameras are the future
Document cameras also have another good thing to them: The ability to record and share online. Because of its built-in microphone and camera, most document cameras can record full lessons. And they also scan files, which diminishes the expense and ecological effect of printing many duplicates.
Another major comfort it offers is the small enough size of the gadget. Because of that, you can easily carry it in your bag as well as transport it anywhere. That by itself makes a document camera an appropriate instrument for all teachers.
Because of their incredible features, document cameras are more popular than ever. And if you still don’t know how to pick one, there are many reviews out there that can help you.
