Command selects the highest quality footage available to play by default. While this is ideal in most situations, there are instances where viewing in standard quality makes sense (when bandwidth utilization is a concern). It is possible to configure the history player to only display SQ video.
Viewing history in SQ instead of HQ reduces the amount of bandwidth utilized on the network. How much the bandwidth utilization will vary is dependent on camera model. When watching multiple cameras at the same time or playing back footage at 2x or 3x speeds, lower bandwidth networks can be saturated by the high data rate of HQ footage. In this instance, playing footage in SQ will result in less buffering and a better user experience.
To watch only SQ footage, select the gear icon in the history player and check the Play only in SQ box. To resume HQ playback, uncheck the box.
Use the same process in multi-camera playback to view only SQ footage.
