Your choice applies for all cameras onyour XProtect Express system.NameAlwaysDescriptionAlways record audio on all applicable cameras.NeverIf you record audio, it is important that you note the following:Never record audio on any cameras. Note that even though audio is neverrecorded, it is still be possible to listen to live audio in the Smart Client.Audio recording affects video storage capacity: Audio is recorded to the associated camera’s database.Therefore, it is important to bear in mind that the database is likely to become full earlier if you recordaudio and video than if you only record video. The fact that the database becomes full is not in itself aproblem since XProtect Express automatically archives (see "About archiving" on page 118) data if thedatabase becomes full. However, you may need additional archiving space if you record audio.oExample: If you use MPEG4, each one-second video GOP (Group Of Pictures) will be stored in onerecord in the database. Each second of audio will also be stored in one record in the database. Thisreduces the database’s video storage capacity to half its capacity, because half of the database’srecords is used for storing audio. Consequently, the database runs full sooner, and automaticarchiving takes place more often than if you were only recording video.oExample: If you use MJPEG, audio is stored in one record for every JPEG for as long as the audioblock size does not exceed the time between the JPEGs. In extreme cases, this reduces thedatabase’s video storage capacity to half its capacity, because half of the database’s records is usedwww.milestonesys.com 89 Advanced configuration
