Default Password: Samsung DVRs often come with a default password, which is commonly set to "000000" (six zeros) or "admin." Try entering these default passwords to see if they work.
Physical Reset Button: Check if your Samsung DVR has a physical reset button on the device itself. This button is usually located near the front panel or on the back of the DVR. Pressing the reset button can sometimes reset the password to the default settings. Refer to the user manual or contact Samsung support for the exact location of the reset button on your model.
Contact Samsung Support: If the default password and reset button methods don't work, contact Samsung customer support for assistance. Provide them with the model number (B74301N) and explain that you've forgotten the password and do not have the remote. They may be able to guide you through a more advanced reset process or provide a solution specific to your DVR model.
Factory Reset: As a last resort, you can perform a factory reset on the Samsung DVR. Keep in mind that this will erase all settings and configurations, including the password, so you will need to set up the DVR again from scratch. To perform a factory reset, locate the reset button on the DVR (if available) or follow the instructions in the user manual or provided by Samsung support.
It's important to note that performing a factory reset should only be done as a last resort, as it will delete all recordings and settings on the DVR. If you have important data on the DVR that you don't want to lose, consider contacting Samsung support for guidance on password recovery options specific to your situation.
Question edited for a lot more clarity.
Question moved to Samsung Home Security.
Swap the camera with no feed for one that does. If that location works, you know the camera is faulty. If the known working camera doesn't work, you know it is the wiring of the power supply to that location.
Power off the DVR: Make sure the DVR is powered off by disconnecting it from the power source.
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.
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.
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.
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.
Very unlikely as this is basically a computer, hard drive, DVR and operating system built into a monitor. Your best bet is to either try and get it repaired or ask Samsung if they can supply a replacement.

Line loss from the camera to the DVR or monitor and ground loops are the most common problems. If you only see black and white from a color camera, it typically means the cable from the camera to the DVR is too long and/or has high loss caused by a poor BNC connector.
Excessive brightness can mean the video signal from the camera is too strong. This can be caused by an impedance mismatch from using the wrong type of video coax (cabling).
Additionally, a camera power supply plugged into a different electrical circuit (not the same outlet as the DVR or montior) can cause ground loop problems that can affect the video quality.
Could be a hard drive, power supply or DVR board issue. Try testing each by replacing except the DVR board which you cannot change without a new board. At which point, a new DVR is recommended.
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.

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.
