If you'd like more specific advice, please provide your and whether this error happens on your phone or local monitor .
Right-click the camera channel panel, navigate to Stream , and select Sub Stream instead of Main Stream. Step 3: Lower Bitrates and Camera Resolutions
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
: Viewing the same device on multiple platforms simultaneously (e.g., iVMS-4200 on a PC and Hik-Connect on a phone). If you'd like more specific advice, please provide
Previous live or playback sessions might not have been properly disconnected, keeping the channel "occupied".
If your cameras have high bitrates, they will trigger resource errors. Lowering these settings frees up substantial processing power.
As noted, new versions of Hik-Connect and NVR firmware can significantly improve stability. This isn't usually a single "feature" you can
How to Fix the "Maximum Number of Channels Under Playback Reached" Here are the step-by-step solutions to resolve this error: 1. Reduce the Number of Simultaneous Playback Channels
The device has a fixed limit on outgoing bandwidth or total remote connections (often 128 links for higher-end NVRs, but much lower for entry-level models).
Understanding the difference between live view and playback is critical. Live viewing uses fewer hardware resources because the recorder simply passes the camera data through. Playback requires the hardware to actively read, decode, and transmit historical video files off the hard drive. If your cameras have high bitrates, they will
Explicitly allocate only the necessary local and remote playback permissions to each account. 5. Update Device Firmware and Apps
: Always check for the latest firmware on the Hikvision Support Portal or via the "Online Upgrade" button in your recorder's menu.
: If the app allows, select "Basic" or "Sub-stream" quality to reduce data load. Verify Specifications : Check your model's datasheet on the Hikvision website to confirm its maximum simultaneous playback capacity.
Select your cameras and slightly lower the , Frame Rate (FPS) , or Max. Bitrate .
The error typically signals that the hardware or software has hit a predefined limit for simultaneous video streams. While a 16-channel NVR can record 16 cameras at once, it often cannot play back all 16 simultaneously to a remote device due to bandwidth or processing constraints .
