> Intelligent video can be used to detect reverse flow of people into a building due to an open
or unsecured door from events such as evacuations.
> Information from the video motion detection functionality of a camera that is located in a
meeting room can be used with lighting and heating systems to turn the light and heat off
once the room is vacated, thereby saving energy.
11.4.5 Industrial control systems
Remote visual verification is often beneficial and required in complex industrial automation
systems. By having access to network video using the same interface as for monitoring a
process, an operator does not have to leave the control panel to visually check on part of a
process. In addition, when an operation malfunctions, the network camera can be triggered to
send images. In some sensitive clean-room processes, or in facilities with dangerous chemicals,
video surveillance is the only way to have visual access to a process. The same goes for electrical
grid systems with a substation in a very remote location.
11.4.6 RFID
Tracking systems that involve RFID (radio-frequency identification) or similar methods are used
in many applications to keep track of items. An example is luggage handling at airports that will
keep track of the luggage and direct it to the correct destination. If it is integrated with video
surveillance, there is visual evidence when luggage is lost or damaged, and search routines can
be optimized.
