The video keeps freezing.

There are many reasons why NVR videos might freeze, but the most critical cause is the decoding at a resolution greater than the NVR’s decoding capacity.

The range of resolutions and number of videos an NVR can fluently decode are defined.

If a video  with large resolution is decoded to multiple channels, it may cause issues in fluently decoding the image.
To resolve the issue, either adjust the resolution or number of channels being monitored.

Check your recorder model and contact us at the site (Customer Support – Contact Us- Contact Us) to gain information about the ideal resolution and number of channels.
