How to Reset a Samsung Security DVR

Why Reset a Samsung Security DVR?

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.

Steps to Reset your Samsung Security DVR

Samsung Security DVR Reset Procedure #1
  1. Reset the unit to factory by pressing both [MODE] and [PTZ] button for 5 seconds
  2. Then enter the 4321.
Samsung Security DVR Reset Procedure #2
  1. Reset the unit to factory by pressing both [MODE] and [CH2] button for 5 seconds
  2. Then enter the 4321.
Samsung Security DVR Reset Procedure #3

This reset will work on Android based DVRs only.  All steps are performed on the device itself.

  1. Turn the device Off
    Wait 2 minutes
    Press and hold the following buttons

    • POWER,
    • HOME
  2. The unit should power on.  Once it does, you can release power.
  3. Use the volume UP and Down buttons to select “Wipe/Factory Reset” from the recovery menu.
  4. Activate the reset using the HOME button.
    When the DVR goes through it’s setup again, it will be at factory defaults. The password will be 4321.
Samsung Security DVR Reset Procedure #4

This reset will work on SDR models. It may also work on other models.

  1. With just the cameras showing, press the following in quick succession using the remote:
    • Freeze
    • Alarm
    • Freeze
    • Alarm
    • Freeze
    • Menu
    • Enter
  2. Make sure you press them quickly, one after the other.   If it doesn’t work the first time, try doing it several times.  It can take many tries to get the timing right. If/when it works, you should get a screen that gives you the option to reset.
Samsung Security DVR Reset Procedure #5

This reset will work on SDR models where procedure #4 failed.  It may also work on other models.

  1. Press the DVR Button to place the system in DVR Mode
  2. Press:
    • Freeze
    • View
    • Return

As with Procedure #4,  you may need to press Freeze, View, and Return in in quick succession a few times to get it to work.  The timing can be tricky.

Samsung Security Reset Procedure #6

To factory reset the SDR-B74301

  1. Reboot the DVR
  2. Once the DVR has rebooted, enter the following sequence on the remote:
  3. UP, RIGHT, 5, 3, 3
  4. You will be prompted to do a factory reset. Confirm

This has been confirmed by several people. Thank you, Sergio! If this works for you, please thank him in the comments below.


These reset procedures cover many Samsung Security DVRs, but not all.  I will add reset procedures to this article as they become available to me.  By design, Security DVRs are made to be secure, and not all of them can be reset by the consumer.  If you have an urgent need related to your Samsung Security DVR, you should contact Samsung directly at their support page Samsung Support, or by calling: 877-349-3149.  For less urgent matters, you can email them directly at Email Samsung Support.  Support is available 7 days a week, 9:00 am – 9:00 pm EST.

    How do I reboot the DVR SDR-B74301. I assume just power down for 2 mins, then power back up? I am trying the sequence for factory default, thats not working. Maybe I am not rebooting properly.

  • aarroyo

    I need some help with the new Samsung Security System I just purchased Kit Model SDH-C85100BF DVR Model SDR-B85300. I have connected everything as instructed. Once I connect the DVR power it does not do anything. It does show the green light in the front but the HDD light is not doing anything nor anything come on the screen. Any help?

    • The HDD light should at least show some activity if the power is coming on. And of course, you should at least be able to get the menu up on the screen. Did you buy the DVR new?

    • I should have mentioned – you can try reset procedures 4, 5, and 6 above for this model DVR. If you purchased it new, though, I’m not sure a reset will provide any benefit. It can’t hurt to try though.

      • aarroyo

        The system is brand new. I even took one back, and had it exchanged because I thought it was defective. The power light in the front is green but the HDD light does nothing. Also, it does not get me to the menu. I can’t see anything come up on the monitor.

        • What I said isn’t 100% accurate – sorry. It is possible that on this model, the HDD light will only come on when it’s recording video, but you should definitely get the startup wizard on the screen. How do you have the monitor connected?

          • aarroyo

            I tried using the HDMI and also the regular VGA cables.

          • And you have it connected prior to powering it on, correct? Sounds like you are doing everything right. The only other possibility is the monitor. Don’t happen to have another HDMI device, like a TV, that you can connect?

          • aarroyo

            Yes, I am connecting all before powering it on. First, I tried with a TV, and noticed it was not working. Then, I connected a computer monitor, and nothing.

          • aarroyo

            The only thing I am not doing is connecting all 10 cameras that came with the system. I am only using 4. The system is a 16 channel one, and came with 10 cameras. I only needed to connect 4 for now. It should not be causing this problem, right?

          • No, that should be fine. You should get the startup wizard regardless of the cameras connected (even if they’re not). The only thing that could prevent it from starting up is if it doesn’t detect a monitor connected.

      • aarroyo

        I was looking at the reset procedure above (4,5,6) but my control does not have the ALARM, FREEZE or VIEW buttons.

        • Yes, that is the case on some remotes. In this case, Sergio’s suggestion seems to work, which is to reboot the DVR, then enter UP, RIGHT, 5, 3, 3 on the remote.

  • Zdenko

    Hi guys my name is zdenko
    I’ve got a scv-2080R system which I got of a friend 4 cameras and the DVR
    I’ve connected everything and it seems to be working fine I’ve got the 4 cameras on screen but I can’t seem to get the login box with the password of the screen at all because I don’t know the password, is there a reset procedure for this kind of model
    If you could please help me that would be great

  • Jason Penrod

    Sdr-c5300n the reset admin to defalt. They had me check the id#:0 & 0 it was a match and fine. Next: freeze alarm freeze alarm return. for this model there is no default password. Once you’ve reset the admin you have to set up a new password a 8 character alphanumeric passwords. And this DOES NOT wipe you recordings JUST THE ADMIN PASSWORD AND SYSTEM TO DEFAULT. You will have to reconfigure your system for your needs and recording preferences as well as date and time but all my recordings were still there right up to the moment of the reset. Good luck! 🙂

    • Thank you Jason, this is really helpful information!

  • soufian

    thank worked perfectly

  • Oscar Hernandez

    By resetting your Samsung DVR, will the reset remove all recordings?

    • Yes, it will. That is by design – a security feature that prevents unauthorized access to the content.

  • Hollisterbulldawg

    I have a SDR-5102. I also used Freeze, Alarm, Freeze, Alarm, Freeze, Return successfully. It took several tries to accomplish, almost spastic in speed. Reminder, put new batteries in the remote. You can’t see the IR beam, so why waste time for 25 cents of batteries?

    A big THANKS to the authors of this post and to NoLimit2Me. Great job, folks!

  • Ed Champion

    Hi. I am a detective with a law enforcement agency. I’m investigation a burglary at a business. The suspects unplugged the security camera system upon entry into the business. I’m hoping that the suspects are on the recording, however, the owner of the business does not know the password for the system. Will a reset erase the recording? Is there way to save the recording? The unit is a Samsung Digital video recorder model SDR-C75300N. Thanks.

    • By design, resetting the recorder will reset the recordings as well. But you may be able to get around that with a call to Samsung – at least under these conditions.

    How about a lorex security DVR? I’ve been trying to reset my lorex DVR because I can’t remember what my password was, really never had to mess with it since I set it up till recently. Turns out I just couldn’t remember the password so I couldn’t log in to review a certain incident that had occurred, so I didn’t really worry I thought to myself it’ll come to me! Well turns out it never did!! Is it possible for any of these codes to work on a lorex?

    • In my experience, with a few exceptions, Samsung is unique in having a known reset procedure for DVRs.

      For Lorex DVRs, if you never changed the default settings, most of them use defaults of username: admin, and password: 000000. If you have changed them and you cannot get back in, I believe the only way to reset it is to contact Lorex and have them do a reset. If they provide instructions though, I’m sure there are plenty of people that would appreciate knowing what that is if you don’t mind taking a few minutes to post back.

  • Diablo Lucifer

    How about a lorex security DVR? I once conversated with support operator on their website & I was told to type “admin” ..! Well to be honest I didn’t even try because it just didn’t seem like “admin” was all I needed to type​ to resolve my lost password I didn’t even bother unboxing it to try “admin”’” thats all they I got from them I was kinda upset cause it seemed like they were not very supportive at all so I’ve had sitting in a box for some time now. I ran into this particular blog by looking for Panasonic blink codes and when I read “how to reset a Samsung

  • Jamie Willumsen

    Hi i have a SDR 1653D but i dont have remote control, is there any other way to factory default the admin code, not bothered about losing footage…… i have also tried the default 4321 and its not a match

    • Jamie, I am not aware of any way to reset a Samsung security DVR without the remote control.

    • Wo_Shit

      Ebay a cheap remote

      • Jamie Willumsen

        I wanted it done 6days ago for a customer to return next day managed to get me hands on a remote and its all sorted, but thanks for the comment i hadnt thought of ebay 😀😀😉

  • Jiwan nepal

    Hey none of this is working for my SDE-3000N im on the log on page and it doesn’t work. Any help would be greatly appreciated.

    • Wo_Shit

      Try from your remote control

      Freeze Alarm Freeze Alarm Freeze RETURN

    • Try “Freeze, Alarm, Freeze, Alarm, Freeze, Return”

    • Hollisterbulldawg

      Make sure you have new batteries in your remote.

  • Pat Landy

    Setup a Samsung SDR-B74301 and didn’t write down the password. The remote does not have “mode” or “PTZ” . Is there a jumper inside that will reset the password….
    Thanks for any help you can give!
    Pat Landy

    • Pat, no jumper of which I am aware in any Samsung DVRs. However, one of the reset procedures listed above for SDR models should work. Let me know if you have any luck.

      • Pat Landy

        Thanks Michael for the rapid response, unfortunately I have a remote that has “all”, “menu”, “mute”, “Submenu” and “Sel” for an enter button and no “Freeze”, “Alarm”, or “Home” buttons.
        I got the system set up and recording and now I want to modify or at least view the results but everything I try results in the unit requesting a device number and sign in…. Any suggestions?
        Pat Landy

        • The default password is usually 4321. Have you tried that already?

          • Pat Landy

            Yes, seems I am handicapped by the type of remote that came with it. Thought there might be a jumper like in the old PC’s

          • Aaron McCrea

            I have the same exact model, and am also trying to reset to default factory settings… I’ve yet figured out how. 🙁

          • Do you have a remote for it?

          • Stacie Lester

            I am having the same problem as above the remote only has “mute” “menu” “submenu” “all” “sel” & then number buttons & play function type buttons but i have not found an answer yet.

          • Julia Luna

            I also have the same issue as these ladies. I have the same remote they seen describing and don’t know what sequence I can use to reset the password. I changed it when it was set up and I can’t remember what I changed it to. Do you know how to reset with this remote?

          • hany mosaad

            Are you solve It ?

          • Sergio Ayala


          • The remote should have a model number on the back (for the remote itself) What is that model number?

          • hany mosaad

            Are you solve this issue ?

          • Sergio Ayala

      I have same issue 😢 are you solve it ?

    • Sergio Ayala


      • Sergio, thanks for the additional information!

      • Ricky Keller

        I have tried the above sequence to no effect. At what screen are you entering the above sequence? Thanks.

        • These instructions are for right after when you boot the DVR. Once you do, use the sequence. That should reset it.

        • Sergio Ayala

          Hello, if your dvr is a SDR-B74301 reboot it and wait for it to be ready, then with the remote control facing the DVR press the sequence UP, RIGHT, 5, 3, 3 then you might be asked to Factory Reset the DVR. (Double check the batteries on your remote and make sure to be pointing the remote to the front of the DVR)
          That just worked fine on my SAMSUNG SDR-B74301

          • Sasha

            Hi Sergio, I really need your help with resetting my DVR back to factory settings, should my cameras be on for this process. My reason for asking that questions is, it keep switching from camera to camera.

          • Roger Swann

            How do I reboot the DVR SDR-B74301. I assume just power down for 2 mins, then power back up? I am trying the sequence for factory default, thats not working. Maybe I am not rebooting properly.

      • Sergio, I added your instructions as reset procedure #6 (with a credit to you). I hope that’s OK. Thanks again!

    • Sergio Ayala


  • Kellie Mahoney

    With the reset will you loose footage that has been recorded?

    • Yes. For security reasons, a factory reset, which allows anyone to access the DVR, will erase all existing information. This is by design.

      • Romin Savani

        Hello Mike have the sdr 75300n, and every time the system boots it comes to clear Samsung logo screen and every button i press it asks for the admin password. i tried the mode and ptz hold and the

      • I’m very happy to hear that the information. Was helpful. Thanks for coming back and adding your experience with this particular reset!

  • NoLimit2Me

    The Freeze, Alarm, Freeze, Alarm, Freeze, Return worked for me but for those of you that seem to have a remote that isn’t working / responding for you, (SDR B3300N) model, press the ID button. Should be below the #9 button. Look at the screen to see what it says. If it shows something like “I/R Remote 0″ and the value below that is a 1, 2 or 3”, then press the “ID” button and hold it down. While holding ID down, press 01, 02, whichever number it is that you need to match the top # and let go of the ID button. Your remote will now work and allow you to enter the sequence. You can check the batteries real quick by turning on the camera on your phone and put the tip of the remote in front of the camera and press a button. Your camera will see the infrared light and you’ll see it on your phone screen where the naked eye can’t see it. Good luck!!

    DO NOT CALL the 877 number. These guys will help reset your system (that sequence is well known) but when getting connected to the ddns they will try to remote login on to your computer and take control. They are not Samsung tech support. When I said i wouldn’t allow them to remote in because my machine is a Microsoft Corp machine (employee) the immediately got frazzled and hung up. I called back to gather info and the email he gave me was something random at Gmail.

    Scammers are annoying.

    • Yeah… And they pop up all over the place. I can’t imagine they make much money from that crap. Generally, people reading and posting comments are a bit higher up on the intellect scale than our knuckle-dragging counterparts. Doesn’t seem like a good place to go fishing for marks.

    • Oh, hold on… The 877 number in the article? No – THAT is a real Samsung phone number. I wouldn’t suggest it to you if I didn’t k ow that for certain. Just checked it again checks out. The email domain is
