This error typically appears when you try to view recorded footage on a client software (like iVMS-4200) or a web browser while multiple users or sessions are already accessing playback streams. This article will explore exactly what this message means, why it appears, and—most importantly—how to fix it.
: This is the most effective way to force-release all currently occupied channels and clear ghost connections. Update Firmware : Ensure your NVR/DVR and the Hik-Connect app

If the problem recurs daily, it is time to upgrade to a higher-channel NVR or migrate to a professional VMS server.
It is critical to distinguish:
Access the recorder's configuration page via a web browser or local monitor. Go to or Record > Parameters . Locate the Substream or Playback settings.
The error typically occurs when you attempt to play back more video channels simultaneously than your Hikvision NVR/DVR or the Hik-Connect app can handle . This isn't usually a single "feature" you can turn on, but rather a hardware or software limitation . Why this happens
Every Hikvision NVR has a specific limit on how many cameras can be viewed in mode versus Live View mode. These limits are determined by the processor chip inside the NVR.
High-definition video places a massive strain on the system's processor. Open the local menu on your recorder. Go to , then click General . Look for Live Playback or Video Parameters . This error typically appears when you try to
The Main Stream demands significant processing power, whereas the Sub-stream uses minimal resources.
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.
