New System to Counter Photo and Video Devices
Incongruity writes "News.com is reporting that a team from Georgia Tech has developed and demoed a system that actively searches for and effectively blinds cameras and camcorders within a 10 meter radius." From the article: "In this system, a device bathes the region in front of it with infrared light. When an intense retroreflection indicates the presence of a digital camera lens, the device then fires a localized beam of light directly at that point. Thus, the picture gets washed out."
You can't see infrared light, so you'd be just fine.
