My main use for this camera is Surveillance. Let me explain....
I use this camera to scope out my back yard during the night. Within the included software, you can set the Motion Sensor to capture people, objects or anything else that moves. When the object or person crosses within the field of vision of the camera, it will automatically start recording onto your computer. Now, I suggest using a motion censor light to brighten the area you would like to view because the Auto Bright setting on the camera is just ok. The camera does not see in the dark well if not at all.
Now thats my personal use. Obviously you can use this camera to chat with friends, or post videos on youtube. I use this camera for so many different things its amazing!
