How To Reset Multistar Dvr Password [work] May 2026

Here’s a step-by-step story that explains how to reset a Multistar DVR password.

It was a quiet Sunday afternoon when Ramesh got the call. “Sir, the CCTV feed is gone from my phone. The DVR is beeping, and I can’t log in,” said Mrs. Kapoor, a worried shop owner. Ramesh, who had installed the Multistar DVR for her two years ago, realized the problem immediately—someone had changed the admin password and forgotten it.

He grabbed his laptop, a small screwdriver, and a USB mouse, then drove to her shop. “Don’t worry,” he said. “We’ll reset it.”

Here’s exactly what he did—step by step—so you can do the same.

1. Executive Summary

This report outlines the standard procedures for resetting a lost or forgotten password on Multistar brand Digital Video Recorders (DVRs). As Multistar DVRs are widely used in security surveillance, lockouts are a common occurrence due to password turnover or employee changes. This document details three primary methods for recovery: the "Forgot Password" graphical interface, the Super Password generation technique, and hardware-level resetting. how to reset multistar dvr password

Step 2: The “Forgot Password” or pattern attempt

On the login screen, Ramesh clicked the “Forgot Password?” link (some Multistar models have it). A window appeared asking for a security question answer. Mrs. Kapoor had never set one. That option failed.

If you have the security answer, enter it. If not, move to the next step.

4. Master Password Generation (Software Tools)

Because Multistar often utilizes generic OEM firmware (commonly associated with the HiSilicon chipset), specialized software tools can generate temporary "super passwords" based on the system's current timestamp.

Common Tools:

Methodology:

  1. The DVR screen displays a "System Time" or "Date/Time" on the login screen.
  2. Input this timestamp into the password generator software.
  3. The software outputs a temporary code (e.g., a 6 to 8-digit number).
  4. Enter this code as the password.
  5. Once logged in, immediately navigate to Account Settings to change the password to a known value.

Step 6: Using Serial Console (TTL) for Advanced Users

If your Multistar DVR is completely locked and lacks a physical jumper, you may need to use a USB-to-TTL serial adapter (e.g., CP2102 or PL2303).

  1. Locate the 4-pin serial header on the motherboard (labeled TX, RX, GND, VCC).
  2. Connect the adapter to your PC (do not connect the VCC pin).
  3. Open PuTTY or SecureCRT at baud rate 115200.
  4. Power the DVR and interrupt the U-boot bootloader by pressing Ctrl+C repeatedly.
  5. Type the command: env default -a then saveenv then reset.
  6. The DVR will reboot with factory defaults.

This method requires technical expertise and a specific firmware knowledge.

Method 3: The Physical Shortcut (RS232 / UART)

For advanced users. Open the DVR case. Locate the 4-pin UART header (often labeled J1, TX, RX, GND).
Using a USB-to-TTL adapter (3.3V), connect to a PC terminal (Putty, 115200 baud).
Power on the DVR. Interrupt the boot sequence by pressing Ctrl+C or Enter within 2 seconds.
At the U-Boot prompt, type: Here’s a step-by-step story that explains how to

env default -a
saveenv
reset

This wipes all passwords and boots into factory default mode.

Step 1: Physical access to the DVR

Ramesh unplugged the power cable from the back of the Multistar DVR, waited ten seconds, and plugged it back in. The familiar beep confirmed it was booting. He connected a monitor via the VGA or HDMI port and attached a USB mouse directly to the DVR.

Why? Many DVR settings can only be accessed locally, not through the network, when the password is lost.
