The error (often alternating with the "Number of streaming channels exceeded limit" prompt) occurs when a Hikvision Network Video Recorder (NVR) or Digital Video Recorder (DVR) runs out of system hardware resources or concurrent stream slots to process simultaneous video streams. This error frequently manifests on the Hik-Connect mobile application, iVMS-4200 desktop client , or the local monitor GUI during high-resolution multi-camera playback sessions.
Stuck or ghost network connections often linger in the background and falsely report active usage.

Fixing this problem involves optimizing the system configuration, reducing bandwidth load, or upgrading software. Step 1: Reboot the System
The table below outlines standard simultaneous streaming and channel limits across common platforms: Step 3: Lower Bitrates and Camera Resolutions Security
Right-click the camera channel panel, navigate to Stream , and select Sub Stream instead of Main Stream. Step 3: Lower Bitrates and Camera Resolutions
Security systems have finite processing power. Decoding recorded video requires significantly more resources than displaying a live view. The error triggers due to three main constraints: 1. Hardware Decoding Limitations Sources: vendor documentation
Every Hikvision recorder has a specific "decoding capacity." This is the total processing power available to turn compressed data into a moving image.
