The "Maximum number of channels under playback reached" error on Hikvision recorders is not a malfunction — it is a based on hardware decoding limits, disk I/O, and firmware design. Understanding whether your bottleneck is the SoC (most common) or the storage subsystem is key to resolution. For most users, switching to substream playback or reducing the channel count offers an immediate fix, while enterprises requiring full-channel simultaneous playback should invest in high-end NVRs or an external VMS. Installations with multi-channel recorders
Who’s affected The issue has been reported across a range of Hikvision products and firmware versions, affecting small-business and enterprise users alike. Installations with multi-channel recorders, central monitoring stations and security teams that frequently review multiple camera feeds at once are most impacted. affecting small-business and enterprise users alike.
Every Hikvision recorder is built around a System-on-Chip (SoC) — typically a HiSilicon processor (e.g., Hi3536, Hi3521). This chip has a fixed number of hardware decoding engines.
