How to reset password on samsung dvr SDS-V3042?

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.

1. Power off the DVR: Make sure the DVR is powered off by disconnecting it from the power source.
2. Locate the reset button: On the back or bottom of the DVR, you should find a small reset button. It is often recessed and may require a pointed object like a paperclip or pin to press.
3. Press and hold the reset button: Using a suitable tool, press and hold the reset button for about 15 to 30 seconds. This will reset the DVR to its default settings, including the password.
4. Power on the DVR: After releasing the reset button, reconnect the DVR to the power source and power it on. The DVR will go through a startup process.
5. Access the DVR: Once the DVR has finished booting up, you should be able to access it using the default login credentials.
   • Username: The default username is usually "admin" or "admin1234". If these do not work, consult the DVR's user manual or documentation for the correct default username.
   • Password: The default password is typically either blank (no password) or set to "4321". If none of these options work, refer to the DVR's documentation or contact Samsung's technical support for assistance.

If you have forgotten your admin password on a Samsung Security DVR, most experts would suggest that you have to contact Samsung and/or send it back to Samsung to have the administrator password reset. While this is true in some cases, it is not always necessary.
Many Samsung Security DVRs have a built-in reset that will allow you to wipe the settings of the device and reset the configuration, including the administrator password. Note that if you perform one of these resets, all settings will be erased and you will have to setup the DVR again. So you should only do this as a last resort - but to reset an admin password, the last resort is the only option.
Reset Procedures for Samsung Security DVRs
There is more than one reset procedure for Samsung Security DVRs, depending on the series and model. But in total, this only amounts to a handful. Since one reset can apply to several different models, I'll provide the resets here so you can try them on yours - I won't associate any one reset with a single model because a complete list of which reset works with what model Security DVR simply doesn't exist. Some of these won't make sense based on the buttons available on your unit or your remote. In those cases, just skip that reset procedure.
If you can perform a reset (in other words, if the instructions match what you have available on your Samsung Security DVR and/or Samsung Security DVR Remote), try it, and let us know in the comments if it works and on what model. If you tell us which model Samsung Security DVR you have, along with your results of each reset procedure, we can compile a complete list of reset procedures by model so that it will be easier for those seeking this information in the future to reset their Samsung Security DVR. Also, if you have a reset that you have used and you know works, let us know and we will add it here. I will update the list of Samsung Security DVR resets/recoveries as I encounter them.
So if one of these doesn't work for you, you may want to check back occasionally. In fact, if you leave your model number in the comments and any specifics about your problem, I'll try to get that specific reset for you. For any of these comments, just use the comment section at the bottom of this page - it is checked regularly.
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.
