1. What is Split Playback
Split Playback allows users to select a video channel and set time period to divide the video files into several parts in the specified time period according to their needs when they are watching playback, so that users can watch videos of different time simultaneously. No doubt it can largely reduce time consumption and improve searching efficiency, coupled with layout of 4/9/16 windows available.
2. How to Watch Split Playback in Local Monitor
This is the default page of Playback. Before using the function, you should make sure that your NVR version is 9.0.9 or above, if not, please update it to the new version.

Figure 2 Split Playback (4 Screen)
Each window get their own file bar, with all of them asynchronous playing back. The moving tool bar of each window only controls the time screen progress of its own channel .
Taking 4 Screen layout as an example, the start time of the first file found in the search time condition will be taken as the start time of calculation T0, and the end time of the last file found in the search condition is taken as the end time T1. Then the time length of each segment Tn= (t1-t0) /n, where n is 4, 9 or 16. Tn has to be an integer.
①The minimum playback value on the split screen is 1 minute, that is, if the search result is less than 1 minute, all the videos corresponding to the search will only be played in window 1, and the other windows will not play.
②Split Playback only supports one channel at one time.
③Slave NVRs do not have this function under hot spare mode.
