At its core, this error is a system alert triggered when your Network Video Recorder (NVR) or Digital Video Recorder (DVR) is receiving or trying to process more video data than its hardware can handle simultaneously. The message can appear in two primary contexts:
How to Fix the Hikvision "Maximum Number of Channels Under Playback Reached" Error
In some cases, the issue is specific to a particular version of the Hik-Connect app. Using an alternative Hikvision-supported client can provide a temporary workaround.
If multiple security guards, managers, or family members are logged into the same Hikvision system and viewing recorded footage simultaneously, the NVR will run out of available playback slots. How to Fix the Error: Step-by-Step Solutions
Export process may reserve a decoding channel. hikvision maximum number of channels under playback reached
This is a common limitation across Hikvision surveillance systems. It does not mean your hardware is broken. Instead, it indicates you have hit a specific software configuration limit or hardware resource ceiling.
For users with standalone Hikvision cameras (not connected to an NVR), the cause could be a low-quality or malfunctioning storage card.
Main-stream video records at full resolution (e.g., 4MP or 8MP), which demands intensive decoding power. Sub-stream records at a lower resolution (e.g., CIF or 1080p Lite) and requires significantly fewer resources.
If you absolutely require multi-channel synchronous playback at all times, you must lower the overall demand of your main streams. Navigate to your camera's . At its core, this error is a system
Decreasing the overall data load on your recorder prevents it from hitting its hardware ceiling too quickly. Log into your NVR via a web browser or the local monitor. Go to > Video/Audio > Video .
: Switching from Main Stream to Sub-Stream (SD or "Fluent" quality) reduces the resource load per channel, often allowing more channels to be viewed at once.
High-bitrate streams can consume the NVR’s maximum outgoing bandwidth, triggering the error even if only a few channels are open. Recommended Solutions 1. Perform a Power Cycle The most effective quick fix is to reboot your NVR or DVR
Depending on whether you are using a computer, a smartphone, or the physical NVR monitor, use the following solutions to resolve the issue. Solution 1: Switch to Sub-Stream for Playback If multiple security guards, managers, or family members
Previous playback sessions didn't close properly, keeping the connection open and occupying the NVR's processing capacity. Hardware Limits:
Here are the most effective solutions, ordered from simplest to most advanced. Method 1: Close Unnecessary Playback Channels
This error is incredibly common, but it does not mean your security system is broken. It means you have hit a hard hardware or software limitation regarding how many video streams can be decoded and processed at the exact same time.
: 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.
Check for new firmware for your DVR/NVR, as updates can fix resource management bugs. Adjust Bitrate:
