How to reset the DVR and NVR video recorder to default factory settings
Here you can select the setting you wish to set to default. If you do not wish to reset the password, do not check the System boxes. Please note Load Default settings do not format your hard drive.
You’d need to enter the system password in the Authentication pop-up window (picture 1), which will lead to restarting your recorder (picture 2).
Navigate to Setup >> System >> Maintenance >> Reset Settings (Picture 3), where you can not select settings to reset so that it will reset your system completely, including the login credentials. You can choose ‘Format HDD‘ if you wish to format your hard drive, leading to erasing any recorded footage.
