Axis standalone microphones can be used in various types of installations. Choose among wall, ceiling, or covert installation. Audio detection may be useful to a security operator interested in listening to what is happening at a specific location in order to evaluate the urgency level in a situation, e.g. a sound of fighting, screaming, slamming doors or gunshots. Audio communication can also be a third scenario, where a network camera with the microphone is used to communicate as an intercom system.
