There is no easy answer. Like the other guy said, the purpose of most cameras is to mimic human vision. To fool a camera like that, you need to understand how your vision is different from a camera and work with that. 1. Your eyes are basically shutter priority with a shutter of 1/20th of a second. Camera dazzlers blink a bright light really fast so it looks steady to a human but confuses the algorithms of a camera's automatic modes. A good photographer could bypass this by using a fully manual mode though. 2. You vision has pretty good image stabilization. If you had some sort of bubbly surface your eyes might be able to compensate better than a camera can. An example is looking into water at fish and so on. A good photographer would probably just use a flash and a fast shutter to bypass this. 3. There are ways to screw up someone using a flash, like that reflective material firefighters wear. 4. Since most digital cameras can see at least a little infrared, just put a really right infrared light in the way. If you're more specific about what you're trying to do we can be more help.
