How do I reset my DVR? It is a Sentient (KGuard EL821) 8 ch DVR and it keeps rebooting once a minute. The mouse and remote do not function and I cannot get to the menu.

To reset a Kguard DVR system, you will need to locate the reset button on the device. This button is usually located on the back or bottom of the DVR, and is typically labeled "Reset" or "Factory Reset". Press and hold the reset button for 10-15 seconds, or until the device powers off and restarts. This will reset the DVR to its factory default settings.

What did you change it to? You can try another monitor that will display that resolution, that is your only option unless you can connect remotely to that system and access the settings.

Samsung Security DVR Default Password

For nearly all Samsung Security DVRs, the default password is 4321. If it hasn't been changed since setup, then you can just use that to access the DVR. The default password is included in the reset procedures for completeness. If you have changed your password or access code for your Samsung Security DVR since it was setup, or if you changed it during the initial setup, use that password in place of the default password. The password will be the latest password that was set on the DVR. If no password has ever been set, then it will be the default.

find the on board battery in the DVR remove it for 10 sec and plug it back this gonna reset your setting

I had the same problem. Did their online tech support and Patty told me to hold down the "rewind" button on the DVR for 20 secs. You should now be able to right click your mouse to access the on screen menu. You will now want to go under system, and a/v setup and change the device to VGA instead of Vout. Now you can reboot and not have to go thru holding down the buttons anymore. Worked for me.
