I forgot the password to My Samsung DVR 5102n .what should I do. This what it only displays on the screen

Try with default ID and password "admin", and "4321".

This particular model doesn't have a reset button, so the only way to reset it is by contacting Samsung who will then give you the reset method.

How to COMPLETELY reset the SAMSUNG SDR-5100N when you`ve forgotten the password and it isn`t the default:
1) Make sure you are just seeing screens on the monitor
2) Push the [DVR] button on the remote so you will send the right commands
3) Enter the following seven key sequence in your remote control [FREEZE] [ALARM] [FREEZE] [ALARM] [FREEZE] [MENU] [ENTER]
4) A menu will pop up asking if you wish to do a factory reset your DVR (you do)
5) You will get a message that says "wait until your system turns off"
6) You will be asked to disconnect the power cable. You should do this for 10 seconds. When your system comes back on you can enter the default login of admin and 4321.

Samsung customer support is superb. You can call 1-877-213-1222 and choose option 2. It won`t list DVR`s starting with "SDR" as ones that can get support on that line, but it is indeed the right place. Hopefully now I`ve saved you 30 min on hold though.

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.

Hi. Put here some images of the DVR's front side, the login screen and the WEB interface.

Are you pressing menu button on the monitor or the DVR?
Your problem may not be the cameras, but between the DVR and the monitor. Found this on page Eng-19 of the user manual which I found on Samsung.com
This monitor was set to password lock when you purchase a new set. Therefore, you must first enter a 4 digit password to activate the On Screen Display... the default password is 4321. Not sure if that helps.
