Yes. If you have a Desktop you want to shoot with you will probably have to buy a Webcam. We recommend getting one with HD resolution. Webcams are not too expensive and they can also be used to generate extra income by camming on MV Live. If you have a laptop, most of them have a decent internal webcam.
In order to record with a computer, you will have to use a recording software on your desktop or laptop, the programs Camera App for Windows and PhotoBooth on a Mac are both great options.
If you have 2 of the above-mentioned devices, you can use both to record at the same time if you want to get some different angles. This can be really fun for your viewers!
