Troubleshooting Hikvision: "Maximum Number of Channels Under Playback Reached"
Playing back high-resolution video (4K/8MP) requires significantly more processing power than low-resolution video (720p/1080p). 3. Sub-Stream vs. Main-Stream Playback
Hikvision is a renowned brand in the security and surveillance industry, offering a wide range of products and solutions for video recording, monitoring, and playback. However, users of Hikvision devices and software may encounter an error message that reads: "Hikvision maximum number of channels under playback reached." This error can be frustrating, especially when trying to access critical footage. In this article, we will explore the causes of this error, its implications, and provide step-by-step guides on how to resolve it.
: Your NVR has a maximum outgoing bandwidth limit (often 80Mbps for entry-level 16-channel units). If your total bitrate exceeds this, you will receive streaming errors. hikvision maximum number of channels under playback reached
Hikvision regularly releases firmware updates that improve performance and resource management. Check the Hikvision support portal for the latest firmware for your specific NVR model. Summary Checklist Instantly lowers processor load. Switch to Sub-Stream Reduces decoding demand significantly. Lower FPS/Bitrate Reduces overall strain on hardware. Close remote sessions Frees up playback channels.
: If multiple users are logged into the same Hik-Connect account or viewing the cameras from different mobile devices simultaneously, the recorder may block new playback requests to save resources.
If you are using or the Hik-Connect app, the software itself has limits on how many simultaneous streams it can manage based on your PC or phone’s RAM and CPU. 3. High Bitrate and Resolution Main-Stream Playback Hikvision is a renowned brand in
When you view playback directly through a monitor plugged into the NVR, you rely entirely on the NVR's built-in decoding chip. Offloading the work to a computer distributes the processing load.
If all checked and limit is below spec, request firmware patch or replace device.
Change the setting from (or "Clear") to Sub-Stream (or "Fluent"). : Your NVR has a maximum outgoing bandwidth
If you are viewing the cameras on a PC via iVMS-4200 or a web browser, your computer's CPU might be struggling to process the video. You can shift this workload to your computer’s graphics card (GPU). Open . Go to Tool > System Configuration > Image .
If basic fixes don't resolve the issue, proceed with these more advanced steps:
| Model Series | Playback Channels Max | Notes | |--------------|----------------------|-------| | DS-7604NI-K1 | 2 | 1 if recording at high bitrate | | DS-7716NI-I4 | 4 | 2 for sub-stream playback | | DS-9632NI-I8 | 8 | 4 for 4K playback | | iDS-7716NX | 4 | Deep learning models reduce available channels |
Hikvision is a renowned Chinese company that specializes in the development and manufacturing of video surveillance products, including IP cameras, NVRs (Network Video Recorders), and DVRs (Digital Video Recorders). Their products are widely used across various industries, including security, transportation, and education. One common issue faced by Hikvision users is the "Maximum Number of Channels Under Playback Reached" error. This paper aims to provide an in-depth analysis of this issue, its causes, and potential solutions.
: Many standard NVRs only support simultaneous playback of 4 channels at once. Higher-end models may support more, but there is always a hard cap defined by the device's decoding capability .
