Live video will be displayed, but—since novideo is kept in the database—users will not be able to play backvideo from the camera.Motion Detection: Select this to record video in which motion (see"Motion detection & exclude regions" on page 101) is detected.Unless post-recording (see the following) is used, recording willstop immediately after the last motion is detected.Event: Select this to record video when an event occurs and untilanother event occurs. Use of recording on event requires thatevents (see "Overview of events and output" on page 111) havebeen defined, and that you select start and stop events.Tip: If you have not yet defined any suitable events, you canquickly do it: Use the Configure events list, located below theother fields.Motion Detection & Event: Select this to record video in whichmotion is detected, or when an event occurs and until anotherevent occurs. Remember to select start and stop events in theneighboring columns.Pre-recordingSeconds [of pre-recording]Post-recordingYou can store recordings from periods preceding detected motion and/orstart events. Select check box to enable this feature. Specify the requirednumber of seconds in the neighboring column.How does pre- and post-recording work? XProtect Express receivesvideo in a continuous stream from the camera whenever the camera isenabled and scheduled to be online. This is what lets you view live video,but it also means that XProtect Express can easily store received video fora number of seconds in its memory (a.k.a. buffering). If it turns out that thebuffered video is needed for pre- or post-recording, it is automaticallyappended to the recording. If not, it is simply discarded.Specify the number of seconds for which you want to record video frombefore recording start conditions (that is motion or start event) are met.Usually, only some seconds of pre-recording is required, but you canspecify up to 65535 seconds of pre-recording, corresponding to 18 hours,12 minutes and 15 seconds. However, if specifying a very long prerecordingtime, you can potentially run into a scenario where your prerecordingtime spans scheduled or unscheduled archiving (see "Aboutarchiving" on page 118) times. That can be problematic since pre-recordingdoes not work well during archiving.You can store recordings from periods following detected motion and/orstop events. Select check box to enable this feature. Specify the requirednumber of seconds in the neighboring column.www.milestonesys.com 59 Wizards
