For example: If both the Pre-event time and Postevent time are set to 10 seconds, a total of 20 seconds of video will be recorded if an event is triggered. This function is supported by the buffer area of the server (time shift cache stream).

Activity Adaptive Stream (active if possible): Check this item to enable activity adaptive stream recording and time shift recording. For cameras combined with time-shift cache stream and multiple streams features, user can make use of activity adaptive streaming for dynamic frame control.

If you check Activate Activity Adaptive Stream and enable time-shift cache stream on the camera, the server will record full-frame-rate video only when an event is triggered on the camera; otherwise, it will only request the I frame data during normal monitoring, thus effectively save lots of bandwidths and storage.

Continuous recording Time

Minimum pre-event time: Due to the limited cache memory on each network camera, the pre-event

time of time shift cache stream on camera may be very short. Then you can choose to set pre-event recording on the server. For example: To set up a minimum of 5 seconds. If the cache memory of the selected Network Camera can only support up to 3 seconds, the Server will switch to enable pre-event recording for 5 seconds by itself, rather than requesting the time shift cache stream from the network camera.

Please note that if you want to enable activity adaptive stream, we suggest you right-clickthe camera on the heirarchical management tree > Camera Settings to open a managment session. Move to Configuraion > Media

>Audio and Video to activate "Time Shift Cache Stream" on the camera and select a stream source. This will help record complete pre-event recording.
