You can use multiple devices to record your Lightboard videos, including a DSLR camera, webcam or smartphone. Whichever device you choose, you will need to mount it to a camera stand so you can position it correctly to capture you behind the Lightboard.
The main requirement for the camera you are planning to use for the Lightboard is that it has adjustable lighting settings (more specifically, the ISO level, aperture and shutter speed) so you can turn the brightness down artificially.
The camera stand should position your recording device to the center of the lightboard glass both vertically and horizontally. You should use a camera stand that is at least 5ft tall.
The microphone you use needs to reach under the Lightboard so the presenter can be picked up behind the glass.
If you use a clip-on microphone or a USB microphone attached to your laptop, use a male to female audio extension adapter cable.
