Hikvision - Maximum Number Of Channels Under Playback Reached [patched]

The "Maximum Number of Channels Under Playback Reached" error typically occurs when a user attempts to play back multiple channels simultaneously on a Hikvision NVR or DVR. The error message indicates that the device has reached its maximum capacity for playing back channels, and no further channels can be added.

Notably, this playback error can appear in specific contexts: from the Hik-Connect app, local playback on the NVR monitor, remote access via web browser, or iVMS-4200 software. The underlying issue is the same regardless of access method.

Uncheck the option in iVMS-4200 or your NVR interface.

Every NVR and DVR has a maximum decoding capacity. While a recorder might support 16 channels of live viewing, it may only have the processing power to decode 4 or 8 channels simultaneously during playback. Playback requires significantly more processing power than live viewing because the system must decompress and read historical data from the hard drive. 2. Stream Resolution and Bitrate

Hikvision cameras record two separate streams: the Main Stream (high resolution for clear storage) and the Sub-Stream (lower resolution for smooth remote viewing). If your NVR supports sub-stream playback, switching to it drastically reduces the decoding load.
