Every Hikvision recorder has a specification called "Simultaneous Playback Channels." For example:
Around mid-2023, Hikvision released firmware v4.61.005 for K-series and I-series NVRs that re-allocated CPU threads. Many users reported that the error disappeared or the limit increased from 8 to 12 channels. Common solutions to resolve this limit include rebooting
The Hikvision "Maximum number of channels under playback reached" error indicates that the recorder has hit its hardware processing limit, often caused by 4 to 8 channel playback restrictions on entry-level models or "ghost" streams from prior sessions. Common solutions to resolve this limit include rebooting the NVR/DVR, switching to sub-stream mode to reduce load, and closing multiple concurrent app sessions.
