This story is about Abramovich's private yacht:
Infrared lasers detect the electronic light sensors in nearby cameras, known as charge-coupled devices. When the system detects such a device, it fires a focused beam of light at the camera, disrupting its ability to record a digital image.
The beams can also be activated manually by security guards if they spot a photographer loitering.
The yacht also has a missile defense system. For the pointer I thank Daniel Lippman.
