- Resolution mismatch
- TV/Monitor Video source
- Bad HDMI or VGA port

Note: These troubleshooting steps are directed to solve output video issues and not video loss or signal loss issues. Video Loss or Signal loss issue is when you are not getting video signal from the camera and you cannot see the live video on the monitor or mobile device.
Output video issue is when you cannot see any image on your monitor (No DVR menus, no layouts) but you maybe able to see live video feedback in your mobile device, we have also included in this article a similar issue to countermeasure the “stuck on the Night Owl Logo” also called the “Frozen screen Issue”.
Before, continuing with the troubleshooting steps, please, ensure that everything is properly connected on your DVR/NVR Unit. On your DVR/NVR the HDMI Cable and the Power adapter is fully connected in your device.
1. Is the DVR getting power?
Is the Power Adapter properly connected to the DVR/NVR?
Some DVR’s (AHD7 and AHD10 series) don’t have Power ON Status LEDs at all. For these products series, you can see the blinking LEDs on the LAN Port or the light of the optical mouse to verify the DVR is getting power. Also, you can verify if it's power on by hearing the HDD’s humming sound coming from inside the DVR.
This is the easiest way to check if your DVR/NVR is powering on, if so, please continue to the second step. If you have determined that your DVR/NVR is not getting power, please visit the link AHD10 Series: NOT POWERING ON for a complete guide to troubleshoot this issue.
2. Monitor Capabilities and settings
2.1 Monitor Capabilities
In some instances when the default video resolution output of your DVR/NVR is greater than the maximum resolution of your TV/Monitor, it will not display anything on the screen. Please, refer to the specifications of your TV/Monitor.
If you try to change the DVR video resolution output to a new resolution and your monitor does not support it, your DVR will default back to its previous video resolution.

After changing the Video resolution Output
Returns to previous resolution if the new resolution is not supported by the monitor.
2.2 Monitor settings
Please, ensure that you have selected the correct input source in your TV/Monitor in which the DVR/NVR is connected Via (VGA or HDMI). keep in mind that most of the new TV/Monitors have more than one HDMI ports, so you must make note of the correct HDMI Port. and select this port as input source on the TV/Monitor input Menu.
3. Check HDMI/VGA Cables and Ports
If after the two previous steps, you still don’t see any image on your monitor, you need to check the HDMI and VGA Cables. Use a different HDMI/VGA Cable from the one you are currently using to confirm if the cable is defective. If you see the image after changing the cable, please, call Tech Support and start a warranty claim for a new HDMI cable (Night Owl only provides HDMI cable in their kits, no warranty claim will be approved for VGA Cables)
If after changing the cables you are still experiencing video issues, Please, call our technical support team for further assistance .
4. DVR gets stuck on the Night Owl Logo or DVR keep restarting
If your DVR gets stuck on Night Owl Logo or DVR keep restarting, please, check if you are using the DVR power supply and not the Camera Power Supply to feed the DVR. If you are using the correct one, try to change it and use the Camera Power Supply to feed the DVR (Only for test purposes).
If the DVR can turn on with the camera power supply, this means that the DVR power supply is has become defective, in this instance you must call our Technical Support Team to start a warranty claim for a DVR power Supply.
If the issue persist after replacing the DVR power adapter for a brand new power supply, Please call our Technical Support Team to ensure that all out troubleshooting steps are followed before a warranty claim is issued.
