However, for current hardware, the limit is a physical wall. Trying to hack the firmware to remove it will void your warranty and likely crash the NVR due to RAM overflow.
This message typically appears on a local monitor (VGA/HDMI) or within the iVMS-4200 client software when a user attempts to play back recorded video from more channels simultaneously than the device’s architecture permits. This write-up explores the technical root causes, the hardware/software limitations involved, and practical solutions to mitigate or resolve the issue.
Instead of playing back 16 channels raw, use Hikvision’s (VCA). However, for current hardware, the limit is a physical wall
If you encounter this error, follow these steps in order to resolve it.
Synchronous playback forces the NVR to align the timelines of every selected camera perfectly. This is very taxing on the processor. Switch to . This write-up explores the technical root causes, the
Recording in 4K or 8MP uses significantly more processing power than 1080p. Fewer high-res cameras can be played back at once compared to low-res cameras.
Select the (adjust both Main Stream and Sub Stream). Synchronous playback forces the NVR to align the
Seeing the error on your Hikvision system—whether on a mobile app like Hik-Connect , software like iVMS-4200 , or directly on the NVR/DVR interface—typically means your hardware's decoding or streaming limits have been hit.
Reduce the resolution or bitrate for the sub-stream to reduce the load during playback. 4. Use Fewer Channels During Playback
Lower the and change the Max. Bitrate to recommended values (e.g., 2048 Kbps for a 1080p camera using H.265 compression). Save the parameters and reboot the recorder. Step 4: Disconnect Co-Streaming Users
Different platforms impose strict limits on how many channels can be viewed or played back at once:
