4.1.5 Hard Drive
This NVR is supplied with a hard drive already installed.
Overwrite: Use this option to overwrite the old recordings on the HDD when the HDD is full. For example, if you
choose the option 7 days then only the last 7 days recordings are kept on the HDD. To prevent overwriting any old
recordings, select Disable. If you have disabled this function, please check the HDD status regularly, to make sure the
HDD is not full.
4.1.6 Resolution
Choose an output resolution that best suits the HDTV or monitor you are connecting to.
Note: When the NVR system is starting up, it will automatically match the best resolution of your monitor.
