Many users forget that scheduled tasks—like continuous recording, motion detection playback, or remote backup software—also consume playback channels. If a maintenance script is downloading footage from 4 cameras in the background, you may only have a few channels left for manual review.
To avoid seeing this message again, implement these best practices:
If you do not have local access, use a web browser (preferably Internet Explorer mode or Pale Moon for full plugin support).

On NVR:
The Hikvision "Maximum number of channels under playback reached" error is not a defect; it is a resource management feature. By understanding that your 32-channel NVR can usually only play back 4, 8, or 16 channels at once, you can design your security workflow accordingly.
The rule of thumb: Assume your playback limit is half of your total recording limit. If you need to review 16 cameras simultaneously, purchase an NVR rated for 32 recording channels, or offload playback to HikCentral.
Have you encountered this error with the new M-Series NVRs? Share your firmware version and channel count in the comments below.
The error message "Maximum number of channels under playback reached" 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
Ironically, long pre-record times can trigger this error in multi-channel playback. When you scrub the timeline, the NVR tries to load 30 seconds before your click for every channel simultaneously.
Recent firmware updates (v4.x and v5.x) have changed the game. Previously, high-end units allowed 16 or 25 playback channels. Newer models (especially value series iDS and M-Series) have adjusted the limits to reserve resources for AI analytics (face detection, ANPR).
| NVR Series | Max Recording Channels | Max Playback Channels (New Firmware) | | :--- | :--- | :--- | | HiWatch (Entry) | 4–16 | 4 | | Turbo HD (DVR) | 8–16 | 8 | | I-Series (Pro) | 32–64 | 16 | | M-Series (Deep Learning) | 32–64 | 8 (Dual 4K) or 16 (1080p) | | E-Series (Value) | 16 | 4 |
Note: If you are using sub-streams for playback (to save bandwidth), the limit might double, but the hard cap usually applies to mainstream playback.
If you are a security professional or a site administrator managing a Hikvision Digital Video Recorder (DVR), Network Video Recorder (NVR), or Hybrid DVR, you may have encountered a frustrating pop-up message: "Maximum number of channels under playback reached new."
This error typically appears when you try to view recorded footage on a client software (like iVMS-4200) or a web browser while multiple users or sessions are already accessing playback streams. This article will explore exactly what this message means, why it appears, and—most importantly—how to fix it.
