However, for current hardware, the limit is a physical wall. Trying to hack the firmware to remove it will void your warranty and likely crash the NVR due to RAM overflow.
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.
High bitrates and ultra-high-definition video consume excessive decoding resources. However, for current hardware, the limit is a physical wall
How to Fix "Hikvision Maximum Number of Channels Under Playback Reached"
This allows you to scrub through footage for individual cameras without taxing the system to sync all frames across multiple channels. 4. Adjust the iVMS-4200 Settings (PC Users) This is particularly effective when the "ghost connections"
Hardware chips can only decode a fixed number of megapixels at one time. For example, an entry-level NVR might decode four 1080p streams simultaneously, but only one 4K stream.
While the "maximum channels" error is primarily about connection limits, insufficient network bandwidth can cause related playback failures that manifest as this error. but only one 4K stream.
: Recorders feature a fixed decoding capability (e.g., capability to handle 4 channels at 4K, or 8 channels at 1080p). Trying to play back eight 4K cameras simultaneously breaks this threshold.
For standalone cameras not connected to an NVR, the error often points to SD card bandwidth limits. Ensure you are using a card. Avoid low-quality or unbranded cards. A card failing to write fast enough will trigger the error.
