MOBOTIX cameras do not need a power supply at the installation point as they are powered over network cable by a standard PoE switch. Only one cable is required, just like networking several PCs. At only 3 Watts, powering the camera for distances over 100m (330 ft) is not a problem. Since MOBOTIX cameras are anti-fogging without heating, they can be powered year round over the network cable. Cost savings are enormous, as demonstrated by the 77-camera installation at the Kaiserslautern World Cup Soccer Stadium. These cameras, including network peripherals, only consume 500 Watts and thus need only about 1/8th of the usual backup power. Not one single camera at the stadium needed an electrical outlet.
