Security systems require massive amounts of computing power to process, compress, and display high-definition video. The "Maximum number of channels" error occurs due to four primary bottlenecks: 1. Hardware Decoding Limitations
: If you frequently need to monitor multiple channels, consider upgrading to a more powerful DVR/NVR that supports more channels. hikvision maximum number of channels under playback reached
If you are viewing via iVMS-4200 or Hik-Connect, your internet upload speed or the NVR’s network capability may be too low to handle multiple playback streams [1]. 4. Limited Processor Capability (DVR/NVR) Security systems require massive amounts of computing power
In simple terms, your recorder (NVR or DVR) has hit its limit for sending out video data. This isn’t necessarily about how many cameras you have, but about how many the hardware can handle. There are three main culprits: If you are viewing via iVMS-4200 or Hik-Connect,
By default, NVRs might try to play back the high-resolution Main Stream. Switching to the Sub-Stream provides lower resolution, which requires far less processing power, allowing you to play back more cameras simultaneously.
Recent updates (e.g., Hik-Connect V6.x) have had reports of this error appearing even when no other users are active.
