Which Product Do I Need to Get a Video Cam Online?

I have a very cool motion tracking video camera that follows a detected movement for a full 180 degrees. I want to mate this camera system with a device that would enable it to be connected to a WiFi network and allow sensed motion to trigger other events. Where do I start? Which Particle product(s) do I really need? Any help would be much appreciated.

What kind of hardware are you running for the video tracking cam? Do you need to send pictures or just events?
