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
In a control room environment, it is common for three or four operators to log into the same NVR. If two operators are simultaneously scrubbing through footage from 16 different cameras each, the NVR may hit its internal decoding limit.
The error message "" on Hikvision systems typically occurs when the system's hardware decoding capacity or the software's concurrent connection limit is exceeded. This often happens when multiple users view footage simultaneously or when the resolution of the cameras being played back exceeds the NVR's processing power. Common Causes & Solutions
How to Fix the "Hikvision Maximum Number of Channels Under Playback Reached" Error Always check your NVR model's datasheet
Explicitly allocate only the necessary local and remote playback permissions to each account. 5. Update Device Firmware and Apps
Warning: Rebooting will stop all live recording for 2-3 minutes.

A: This typically indicates you're operating near your device's limits. The error appears when usage spikes above the threshold due to multiple users accessing the system simultaneously or when "ghost" connections accumulate over time.
A: The limit is hardware-based and cannot be changed through settings. The only solution is to upgrade to a more powerful recorder model with higher decoding capabilities.
By adjusting the playback resolution and reducing the number of cameras viewed simultaneously, you can easily bypass the "Maximum number of channels under playback reached" error, as described in this YouTube tutorial . The error message "" on Hikvision systems typically
If your business workflows require constant, synchronized 16-channel playback at high resolutions, you will ultimately need to upgrade your hardware to a higher-tier NVR (such as an or DeepinMind unit) that features advanced decoding processors. If you want to troubleshoot further, tell me: What is the exact model number of your Hikvision NVR/DVR?
Are you seeing this error on the mobile app or on the NVR's local monitor ?
When you check your cameras on your phone and close the app, Hik-Connect is supposed to send a signal to the NVR to drop the stream. If your network dips or the app hangs, that connection thread remains open on the recorder. If this happens repeatedly across multiple devices, the NVR fills up its link allocation—often maxing out its connection pool—blocking new attempts.
: A simple restart of the NVR can clear "ghost" connections that might be falsely occupying your stream limit.
If you consistently need high-volume playback or have outgrown your current NVR, consider these strategies:
