Factory reset for sdr-b85300 - Video Cameras

Try this

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.

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.
