If the monitor connected to your X4 displays a black screen, please follow the steps below to check:

1. Reduce Sub-stream: Go to the Device Management—Advanced Settings—Record—Parameters, then reduce the Sub-stream of your camera and apply it.

2. Go back to the main menu, then click the Shut Down button to reboot your system again.

X5C can support HDMI/VGA output simultaneously.

If the camera included in your original package is damaged or does not meet your needs, you can purchase additional cameras as per the following requirements:

For DVR wired kit/X5, you can add the camera with a BNC injector from a third party.

For NVR POE wired kit/X4, you can choose to purchase the camera that supports ONVIF from a third party after you upgrade the system firmware to the latest version.

Please kindly note that if you don’t have a hard drive installed, the DVR will keep beeping and can’t be disabled. If so, you may have to get an HDD to install and format.

If you have already installed an HDD, please check the HDD status by going to the monitor > Device Management > Advanced Settings > HDD. If it shows abnormal, please try to format it again and we do recommend you save a backup of important clips before formatting by going to Advanced Settings > Export.

Meanwhile, please also check below information:

1. Please check the power adapter between the DVR and the cameras, the DVR should be 1A, and the camera should be 1.5A.

2. IP address conflict can also cause beeping, so please go to Device Management—Advanced Settings, and confirm whether your DVR IP address conflicts with the IP addresses of other network devices in your home, if it is, please disable the Enable DHCP button to modify the IP address of your DVR.

3. Please ensure the firmware of your system is updated to the latest by going to Device Management—Advanced Settings—Maintenance—Upgrade.

4. Unplug and plug the power adaptor again, after that, click the Shutdown button then choose the Reboot button to reboot your system.

5. You may also try to default the system by going to the Device Management—Advanced Settings—Maintenance—Default.

Please kindly note that X5C beeping all the time can have the following issues and you may check which one caused this by going to Menu > Configuration > Exceptions and selecting one by one:

1. HDD Error: Errors when writing or not formatting the Hard Disk before using or not using HDD.

2. Network Disconnect: No Ethernet, so please make sure the NVR is connected to a functional network and online.

3. IP Conflict: Please confirm whether your NVR IP address conflicts with the IP addresses of other network devices in your home by going to Configuration-Network-General, if it is, please disable the Enable DHCP button to modify the IP address of your NVR.

4. Record Exception: No video hard disk exists, so please check whether you have an HDD installed.

If the monitor connected to your X5 displays a black screen, please follow the steps below to check:

1. Power Check: Please check the power adapter and ensure that it is functional. A quick test will be swapping the camera power adapter for the DVR power adapter. 

2. Reduce Sub-stream: Go to the Device Management—Advanced Settings—Record—Parameters, then reduce the Sub-stream of your camera and apply it.

3. Go back to the main menu, then click the Shut Down button to reboot your system again.
