How to reset Admin password on Samsung SDR-C5300N Digitalvideo recorder


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
Reset the unit to factory by pressing both [MODE] and [PTZ] button for 5 seconds
Then enter the 4321.
Samsung Security DVR Reset Procedure #2
Reset the unit to factory by pressing both [MODE] and [CH2] button for 5 seconds
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.
Turn the device Off
Wait 2 minutes
Press and hold the following buttons
POWER,
HOME
VOLUME UP
The unit should power on. Once it does, you can release power.
Use the volume UP and Down buttons to select "Wipe/Factory Reset" from the recovery menu.
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.
With just the cameras showing, press the following in quick succession using the remote:
Freeze
Alarm
Freeze
Alarm
Freeze
Menu
Enter
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.
Press the DVR Button to place the system in DVR Mode
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
Courtesy Sergio Ayala
To factory reset the SDR-B74301
Reboot the DVR
Once the DVR has rebooted, enter the following sequence on the remote:
UP, RIGHT, 5, 3, 3
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.

Forgot password


This is one of those annoying but easy things. If you can't remember the password and logon then your only option is to reset to factory settings (hold down reset for 15 seconds on this model i think). That wipes out all the settings and you then need to set it up again as it will be have just like the day you bought it. Depending on your setup that might mean you just have to set the time, turn on dhcp, setup your wifi identifier and security and put in a new password and logon.

I don't know what your situation is at home/work where ever the router is being used ie if you have roommates or people you don't want to have access to this. If thats not the case what I suggest to most people is to write down the information on a piece of masking tape and stick it on the bottom of the router. If you have a problem you can lookup the password or a setting quickly. If its at home for example and your conecerned about security if someone can look at the bottom of the router you really do have other bigger problems than network access ;-]

GE Simon - Reset Installer Code & Remove Sensors


I am sure you already guessed this but it appears someone has changed the default installer code. Using the default installer, dealer, or master codes defeat the purpose of a security system as most criminals know the default codes. The only way I know of to regain control of this panel is to reset it to factory defaults. This does mean that you will have to completely re-progam the system. I would document as much stuff as you can from the display before resetting it. If you don't have a copy of the installation manual I am providing a link below. Hope this helps.
