Video image is and always will be the key to security management. However, the accurate interpretation of images will rely increasingly on other data sources to add vital information to video for better interpretation of live alerts. Sound is a fundamental source of data for use in security: it is the primary warning signal and is omnidirectional, whereas cameras can only see what they are looking at. By associating SENSIVIC sound devices and the best cameras on the market this provides operators with increased senses for greater real time management of security.
