When it comes to teaching people, it's often the detail that counts and more is always better. Being able to share your ideas and knowledge with a large audience can be difficult but a huge benefit. With the Optoma DC550, you simply position items under the camera, connect it to a projector and show everything on the big screen live as it happens. The DC550 features an 8MP sensor, 544x total zoom and up to 30 frames-per-second video (at full resolution) for stunning image quality and performance allowing you to see detail often not visible to the human eye. Take photos or video using the camera function and include them in future presentation - it's all so easy. Create more engaging lesson content by easily capturing images, video and audio with the DC550 document camera. You can even take a video of a science experiment with the document camera, save it on your PC/laptop via USB or save to a SD card and use it in your next class and students can record their demonstrations during presentations for later review. The DC550 is powerful, robust and full of useful features that will revolutionize any classroom lessons or meeting room presentations.
