Higher resolution (e.g., 4K/8MP) consumes more decoding power, reducing the number of simultaneous playback channels.
The message "Maximum number of channels under playback reached" appears on Hikvision recorders and software when an attempt is made to play back recorded video from more channels simultaneously than the device or application allows. This limit is enforced to protect device performance, prevent overloads of decoding resources, and ensure stable recording and live-view operations. Understanding why this limit exists, how it affects system operation, and how to resolve or work around it helps administrators maintain reliable surveillance performance while balancing user needs for multi-channel review.
