    Troubleshooting IP Cameras

    August 21st, 2020

    Below are some problems that can be encountered with IP Cameras, and ways to resolve them.

    No cameras appearing on screen and not showing in camera registration

    Check the network cable is wired correctly and is not damaged. Use a cable tester to verify cable integrity.

    Ensure the cable is terminated to T-568A on both ends, or T-568B on both ends.

    Do not terminate T-568A on one end, and T-568B on the other, as this will create a Crossover cable which is not suitable in this application.

    When using terminating cable, it is not a matter of wiring them in any order as long as its the same on both ends. This will not work. This is a common problem that is encountered on new installations.

    Below is a video which covers in depth troubleshooting.

    Cameras are shown in registration with a connected status, but cannot live view

    If cameras are added to the recorder and show as connected, but you are unable to view them live or on playback, check the below things. 

    • Check the camera model and the recorder model, to ensure that the recorder can handle the camera's resolution.
    • Ensure the image settings are set correctly. Right click on the live view of the camera and select Image.
    • Default the camera encode settings.

    Over Decode Shown on Camera Playback

    This error can normally be rectified by enabling substream recording.

    See the link below.

    Over Decode Shown on Camera Live View

    • Ensure camera substream is enabled. 
    • Drop camera resolution and/or bit rate.

    Cameras Dropping in and out or stuttering

    • Check CAT5 cable for damage and correct termination.
    • Check camera connection for water damage.
    • If the cameras are connected through a network switch, ensure the recorder is connected to the up-link port of the switch. If the recorder is receiving more then 100mbps of data from the switch, and it is not connected to an up-link port this creates a bottleneck.

    Unable to Connect to the Web Interface

    Ensure that the IP address of your PC is in the same range as the device you are trying to access.

    If you get an error that says "Unable to open the search page", "This page can't be displayed" or something similar, your PC might not be in the correct IP range. If you are trying to log into a camera with the IP Address of, your PC's IP address should be in the 192.168.1.x range.

    For more information on how to change the IP Address of your PC please see this guide.

    Check that you are using Internet Explorer and not Microsoft Edge or another browser.

    The icon for Internet Explorer looks like this  , whereas the icon for Microsoft Edge looks like this .

    The plugins for our products are designed for Internet explorer, so you may run into issues using another web browser.

    Clear your Browsing History.

    If the Web Interface has "sys." or "com." in front of text or it doesn't load some elements correctly, you will need to delete your browsing history to fix it.

    Press CTRL + SHIFT + DELETE.

    Untick "Preserve Favourites website data" and Tick "Temporary Internet files and website files", "Cookies and website data", "History" and "Passwords", then click "Delete".

    Internet explorer will prompt you when it has finished deleting your browser history. Refresh the page

    Delete Internet Explorer's Plugins

    Our cameras and NVRs use a plugin made for Internet Explorer and, depending on the firmware of the device, may present a different version of the plugin which can cause conflicts.

    To resolve this, close Internet Explorer then find the directory below and delete the "webrec" folder containing the plugins.

    C:\Program Files\webrec\  or  C:\Program Files (x86)\webrec\

    Cannot Find Network Host Error

    • Check CAT5 cable for damage and correct termination.
    • Check camera connection for water damage.
    • Check IP address of the camera using config tool, to ensure it has not changed.
    • Plug the camera directly into the recorder with a CAT5 patch lead.
    • Factory reset the camera - See this article.
