Here is a comprehensive guide to understanding why this happens and how to fix it. Why This Error Happens
Are you seeing this error on the mobile app or on the NVR's local monitor ?
: Using iVMS-4200 on a PC and Hik-Connect on a phone at the same time for the same device can trigger this restriction. Recommended Solutions
Previous live or playback sessions might not have been properly disconnected, keeping the channel "occupied". Here is a comprehensive guide to understanding why
: Accessing the unit's local interface while pulling multiple remote playback streams through Hikvision iVMS-4200 software and the mobile application at the same time locks out extra channels.
A simple reboot often resolves the issue by clearing all active connections. This is particularly effective when the "ghost connections" from app hangs are suspected.
If you encounter this error, follow these steps in order to resolve it. This is particularly effective when the "ghost connections"
If you consistently need high-volume playback or have outgrown your current NVR, consider these strategies:
Unlike live view (which just shows the feed), requires the CPU to decompress and seek through recorded files. The error appears when you try to play back more channels (cameras) at once than your system’s "Decoding Capability" allows.
This error essentially means your recording device has reached its maximum simultaneous decoding capability for playback, preventing you from adding more cameras to your live view or playback screen. updating device firmware to version 4.60+
The "Maximum number of channels under playback reached" error in Hikvision systems arises when NVR/DVR units exceed their maximum simultaneous remote streaming, bandwidth, or channel limits. Effective solutions include rebooting the recorder to clear hung sessions, updating device firmware to version 4.60+, and reducing stream quality to "Fluent" mode to lower resource usage.

: You are trying to watch the video on your phone and computer simultaneously. Step-by-Step Fixes
Hikvision NVRs (Network Video Recorders) and DVRs (Digital Video Recorders) are limited by their hardware—specifically, the processor (CPU) and the decoding engine. While an NVR might support 16 cameras for recording , it may only have the capacity to decode and display 4, 8, or 16 channels simultaneously during playback .
Instead of trying to view 16 cameras simultaneously in playback, try viewing 4 or 8 at a time. The error frequently occurs because the system cannot manage too many simultaneous high-resolution streams, and reducing the simultaneous count allows the CPU to handle the request. 5.
