NVR Max Live Channels Limit Reached Error

Home › Forums › Viewtron Security Camera Systems Support › Viewtron NVRs › NVR Max Live Channels Limit Reached Error

  • Here is a question we got from a customer using our Viewtron 16 channel NVR  this also applies to our other Viewtron NVRs / DVRs:

    “I have 8 cameras, but when I view them all live on my monitor, one camera does not show up and I get a Max. live channels limit reached message. Is that a monitor issue or an NVR issue?”

    It is NOT a monitor issue. It is an NVR firmware issue. If your Viewtron NVR is running firmware version 1.4.10 or lower, upgrading it to firmware 1.4.12 fixes it.

    How do I fix the Max Live Channels Limit Reached error?

    Upgrade the NVR firmware to 1.4.12 or later. You can check the version your NVR is running under Settings > System > Basic (in the Information section). If it is 1.4.10 or lower, here is how to upgrade it:

    If you need the 1.4.12 firmware file, email us your current FW version and we will send you a link to the upgrade.

    1. Download the firmware file and copy it onto a USB thumb drive.
    2. Plug the USB drive into the USB port on the back of the NVR.
    3. Go to Settings > System. On the left menu, select Upgrade (under the Maintenance section).
    4. The firmware file is listed on that page. Highlight it and select the Upgrade button.

    The upgrade takes a few minutes and the NVR reboots by itself when it is done. Do not power off the NVR during the upgrade.

    What if the error is still there after the firmware upgrade?

    Check the sub stream resolution of your cameras. When you view cameras in a multi-camera layout, the NVR pulls the sub stream from each camera. If a sub stream resolution is set too high, the NVR cuts camera views to save its CPU resources. Make sure none of your cameras have a sub stream higher than 704 x 576.

    You can check this under Start > Settings > Record > Record Substream.

    How many cameras can the VT-NVR-16 show live on one monitor?

    The VT-NVR-16 can show up to 16 cameras live on HDMI output 1. HDMI output 2 is limited to 9 cameras. You can see all of our Viewtron IP camera NVRs here, and watch a demo of the NVR in this 16 channel NVR video.

    If you still see the error after both steps, email us at info@cctvcamerapros.net with your NVR model, firmware version and the exact make and model of your cameras.
