How to Reset Samsung Security Camera Password Goprocamera27, May 8, 2026 Forgotten your Samsung security camera or DVR password? You’re not alone. Thousands of users lose access to their SDR-C5300N, SDE-4001N, SDR-B74301, and other Samsung DVR systems every year due to forgotten passwords, employee turnover, or inherited equipment with locked settings. The good news: you can reset the admin password without professional help—often in under 10 minutes. This guide reveals all proven methods, from remote control codes and front-panel button combos to hardware resets that preserve your recorded footage. Whether you’re locked out of an older SDR-series DVR or a newer Android-based model, we’ll walk you through the exact steps to regain access and secure your system again. Use Remote Control to Reset Samsung DVR Password Freeze > Alarm > Freeze > Alarm > Freeze > Return (Most Reliable Method) This is the most widely successful method for SDR-C5300N, SDE-4001N, and similar SDR-series DVRs. It triggers a hidden factory reset menu through a precise button sequence. Steps to Reset: 1. Ensure only live camera feeds are visible—no menus open. 2. On your Samsung IR remote, press these buttons quickly: – Freeze – Alarm – Freeze – Alarm – Freeze – Return 3. A prompt should appear: “Do you want to perform a factory reset?” 4. Use the Left arrow, then press Enter to confirm. ⚠️ Critical Timing Tip: Press each button within 1–2 seconds. Delays will cancel the sequence. Try 3–5 times if it fails initially. This method has been verified by users like taste_the_savings, who successfully reset their SDE-4001N using this exact combo. Freeze > View > Return (Alternative for Unresponsive Units) When the Freeze > Alarm sequence doesn’t work, try this variation: Press the DVR button to ensure the system is in DVR mode. Rapidly press: – Freeze – View – Return Repeat up to 5 times. 🔄 Firmware Sensitivity Warning: This shortcut may not work on newer firmware versions. Success depends on your DVR’s software build. UP, RIGHT, 5, 3, 3 (Specific to SDR-B74301) Submitted by user Sergio Ayala, this method works specifically on SDR-B74301 models. Steps: 1. Reboot the DVR. 2. As the screen flickers back on, press: – UP – RIGHT – 5 – 3 – 3 3. A reset confirmation will appear. Confirm to proceed. ✅ Pro Tip: Enter the code as fast as possible—before the main menu loads. Speed increases success rate. Freeze > Alarm > Freeze > Alarm > Freeze > Menu > Enter (Fallback Option) If the Return button doesn’t trigger the reset, try this variation: After the third Freeze, press Menu, then Enter. This works on certain firmware builds where Return is mapped differently. 🔁 Multiple Attempts Recommended: Even slight pauses break the sequence. Practice the rhythm before serious tries. Reset Without Remote: Front Panel Button Methods MODE + PTZ Button Combo (Universal for Most Models) Lost your remote? Use the physical buttons on the DVR’s front panel. Steps: 1. Locate the [MODE] and [PTZ] buttons. 2. Press and hold both for 5 seconds. 3. Release, then enter: 4321 4. The DVR will factory reset and reboot. ✅ Works on: Most SDR and SDE models 🔐 Default password after reset: 4321 ✅ User-Tested: Verified on multiple units where remotes were lost or broken. MODE + CH2 (For Older Models Only) This method applies to pre-2015 Samsung DVRs and is ineffective on modern units. Steps: 1. Press and hold [MODE] and [CH2] for 5 seconds. 2. Enter 4321 when prompted. ⚠️ Limitation: Does not work on SDR-C5300N or SDE-4001N. Use only if your model is confirmed legacy. Android-Based DVR: Recovery Mode Reset Newer Samsung DVRs run Android OS and support smartphone-style recovery resets. Power + Home + Volume Up Method Steps: 1. Power off the DVR completely. 2. Wait 2 minutes to discharge capacitors. 3. Press and hold: – POWER – HOME – VOLUME UP 4. Release POWER when the unit starts up (keep holding HOME and VOLUME UP). 5. A recovery menu appears. 6. Navigate to “Wipe/Factory Reset” using Volume Up/Down. 7. Press HOME to select. 8. Confirm and wait for reset to complete. 9. Choose “Reboot System Now”. ✅ Result: All settings and passwords cleared 🔐 Default password: 4321 🛠️ Requirement: Your DVR must have HOME and VOLUME buttons. Not all models include them. Preserve Footage: CMOS Battery Removal Reset Why This Method Is Unique If you must keep existing footage (e.g., for legal evidence), avoid software resets—they erase data. Instead, perform a CMOS battery reset. Steps for SDR-C5300N and Similar Models Unplug the DVR from power. Open the casing to access the motherboard. Locate the CMOS battery (a small, round, silver watch-type battery). Remove it and wait at least 2 hours (to fully drain BIOS memory). Reinsert the battery. Close the case and reconnect power. ✅ Outcome: Admin password is cleared ✅ Recordings remain intact 🔐 Post-reset login: Try 4321 or leave blank 💡 Why it works: The CMOS battery maintains low-level settings (including password). Removing it resets configuration without touching the hard drive. ⚠️ Warning: Opening the unit may void warranty. Only attempt if you’re comfortable with hardware. Fix Unresponsive Remote: Reprogram Remote ID Remote ID Mismatch Prevents Reset Even with the correct sequence, a remote with wrong ID won’t work—common with third-party or eBay remotes. Reprogram Remote ID to Match DVR Steps: 1. Press the [ID] button on the DVR’s front panel. 2. Note the displayed ID (default is usually 0). 3. Hold the DVR’s [ID] button, then enter a two-digit code on the remote (e.g., 08). 4. Press [ID] again to save. ✅ Test immediately: Try navigating menus or volume control to confirm sync. 🔄 Troubleshooting Tip: If the remote came from eBay, reprogramming is essential—its ID likely doesn’t match your DVR. Model-Specific Reset Guide Model Best Reset Method Default Password SDR-C5300N CMOS battery removal or Freeze > Alarm sequence 4321 SDE-4001N Freeze > Alarm > Freeze > Alarm > Freeze > Return 4321 SDR-B74301 UP, RIGHT, 5, 3, 3 after reboot 4321 Android DVRs Power + Home + Volume Up → Recovery Mode 4321 Old SDR/SDE Models MODE + PTZ → Enter 4321 4321 📌 Key Takeaway: Always confirm your model number before proceeding. Methods vary significantly between firmware versions. Post-Reset: Secure Your System Immediately Set a Strong New Password After reset, your DVR is vulnerable. Change the password right away. Steps: 1. Go to Settings > System Settings > User Management. 2. Select Admin account. 3. Enter a strong password: – At least 6 digits – Avoid 1234, 0000, or birth years – Use a unique sequence (e.g., 739218) 🔐 Never leave it as 4321—this is the first password hackers try. Lock Down Physical Access A technician confirmed: you can’t reset a Samsung DVR remotely without physical access. But that also means: – Anyone with hands-on access can reset and download footage. – Store the DVR in a locked cabinet or secure room. Secure Remote Viewing (If Enabled) If you use remote access: – Set a static IP for the DVR. – Forward ports like 9000, 80, or 443 on your router. – Use DDNS if you lack a static public IP. – Change default RTSP/HTTP ports to avoid bot scans. – Never expose the DVR directly to the internet—use a firewall or VPN. Warnings and Limitations Factory Reset Erases Data Software-based resets (remote or button) typically: – Delete all user accounts – Wipe network settings – Remove scheduled recordings – Erase stored video footage ❌ Avoid these if you need to preserve evidence. CMOS Reset Is the Only Data-Safe Option Only removing the CMOS battery clears the password without touching the hard drive. All other methods are full factory resets. No Universal Backdoor Password Samsung does not provide backdoor codes like “admin/admin”. Customer support may require proof of purchase and often won’t assist with password recovery. Last Resort: Alternative Solutions Replace the DVR One user paid a modest cost to replace their unit with a newer model supporting mobile apps, cloud backup, and easier remote access. 💡 Upgrade consideration: Modern NVRs offer better security, remote viewing, and password recovery options. Use as Standalone Recorder If playback works but you can’t reset, use the DVR for: – Local monitoring – Footage review – Evidence export (if supported) You won’t be able to change settings, but it’s not completely useless. Call a Professional Some security integrators use: – JTAG tools – Firmware reflashing – Direct board access These can bypass passwords but cost more than a new DVR in many cases. Resetting your Samsung security camera password is possible using remote sequences, front-panel buttons, recovery mode, or CMOS battery removal. The Freeze > Alarm > Return method works for most SDR models, while CMOS removal is the only way to reset without losing footage. Always set a strong new password and secure physical access. If all else fails, consider upgrading to a modern system with better user management and remote support. Help
