Go to Camera Management > Encoding Parameters . Set Substream resolution to low (e.g., 704x480). When you do playback, switch to Substream view. This reduces the decoding load by 80%, allowing you to play more channels simultaneously.
Here is the of what this means, why it happens in newer firmware/software versions, and how to resolve it.
He unchecked the Main Gate and checked the Rear Exit. Total: twelve. Go to Camera Management > Encoding Parameters
| NVR Model Type | Typical Playback Limit (Real-time) | | :--- | :--- | | Value Series (E.g., DS-7604) | 2-4 channels | | Pro Series (E.g., DS-7716) | 4-8 channels | | Deep-inMind / AcuSense | 8-16 channels (with substreams) |
Close unnecessary playback windows before opening a new camera timeline. 2. Switch from Main Stream to Sub Stream This reduces the decoding load by 80%, allowing
Recent firmware updates (post-2023/2024) and newer versions of iVMS-4200 (V3.x) have changed how this limit is enforced:
Always check your NVR model's datasheet. Look for the "Decoding Capacity" section. It will look like this: Example: 1-ch @ 8 MP / 4-ch @ 1080p. If you exceed these combinations, the error will persist. Update Your Firmware Total: twelve
"Okay, let's try the new firmware," Elias said, his voice trembling slightly. He had heard rumors about the newer Hikvision updates tightening security protocols, but he hadn't updated this machine in months. He was running version 5.7. The newest was 5.9.
The error (often alternating with the "Number of streaming channels exceeded limit" prompt) occurs when a Hikvision Network Video Recorder (NVR) or Digital Video Recorder (DVR) runs out of system hardware resources or concurrent stream slots to process simultaneous video streams. This error frequently manifests on the Hik-Connect mobile application, iVMS-4200 desktop client , or the local monitor GUI during high-resolution multi-camera playback sessions.
