Since there are thousands of DVR brands on the market and the way to reset the password can vary from one model to another.

The first step of doing a password reset on an H.264 DVR is to consult the equipment's manual or to contact the DVR's a dealer/reseller, most of the resellers (TVT, Dahua, Lorex, Swan, FLIR, Samsung, Panasonic, Axis, Uniview, , Zmodo) support their products.

However, sometimes you have an H.264 DVR with an unknown brand and there's no manual available or no team. If you have lost the password for your non-branded / generic H.264 DVR, you could try the password reset methods shown in this guide.

Below are listed the techniques and the procedures we will deploy to reset the password for H.264 DVR. As you can see, there are four basic password procedures that work on most H.264 DVRs.

  4. Use a jumper to reset the passwords

2. H.264 DVR Master Password Generator

Many CCTV manufacturers provide master password generators to allow administrators access to their CCTV products. Usually, they use the current date of the security system in order to generate a super password. Others may use the serial number of the equipment.

A lot of the recorders on the market are generic DVRs manufactured in China and in many cases re-branded by third-party companies. Y

You can tell by the user interface which is exactly the same across many brands such as HD iDVR, Everfocus, Everest, Sansco, 5716, 6008T-EL, HA-1648, CP-Plus, Citrox, BB-4CH, Yoko, TVT, Super Live Pro DVRs,  Kare, XVIM, and other generic brands simply named “H.264 network”, “H.264 DVR”, etc.

If your DVR has a login screen similar to the one shown below, then most likely it's an H.264 generic DVR. Keep in mind that the user's interface color scheme may have been further modified by the re-branding company.

You need to find out what's the date on your security system DVR. Run the machine and simply check the timestamp on the screen. The date is used by the password generators to create a unique super password. So, take a look at the monitor and note the timestamp (as shown below).

Note: DVR master password generators will work only with specific DVR models.

If your DVR runs on a chip manufactured by Hisilicon, then you can check the Hisilicon password generator to get a working password for your recorder. This generator works with these models: Hi3511, Hi3512, Hi3515, Hi3520, Hi3531, Hi3532, Hi3521, Hi3520A, Hi3535, Hi3520D, Hi3530A, Hi3535A.

On the internet, you can find 3 versions of the Hisilicon H.264 DVR password generator that work with the models mentioned above. Try all of them one by one until you're able to reset the password. Below are the links to the DVR password generators.

This is a common thing since many Chinese manufacturers sell their DVRs or cameras to third-party companies which they resell under local not-so-known brands or simply as H.264 DVR. In itself, H.264 is not really a brand but just the name of the compression algorithm. You can download the generic H.264 password generator at this link.

3. Remove the battery to reset the DVR

A few H.264 DVRs can be reset by another technique: removing the battery from the motherboard. By doing that, the clock of the system will be reset and the DVR will go back to factory defaults and you can log in by using the default username and password.

How long do you need to have the battery removed? It depends on the DVR's model number. Usually, it takes 10 minutes for the card to be discharged. So, keep the battery out until the DVR's internal clock has gone to default. Remove the battery from the DVR as illustrated below.

When the clock runs out of the battery, the timestamp on the recorder goes to 01/010/2000 and you either can try the default password or use the DVR password generator to create a new password based on this date.

Most likely the default username will be admin and password: empty, 12345, or 123456. For old Dahua DVRs, the password can be “000000”.

4. DVR reset using a jumper

In order to perform this kind of reset, you need to open up the cover of your DVR and find the reset pins on the motherboard.  The H.264 DVRs that have these pins are for example old Dahua DVRs, old TVT DVRs, Swann DVR models, etc.

An example is shown below can be reset by closing the two contacts (pins) for 3 minutes. Once you close the circuit (via the jumper), the H.264 DVR will automatically reboot and come back online without any password or just using the default one. Try to log in.

5. Contact the manufacturer

If you tried all the methods explained above but you still can't reset the password, then as the last option you should contact the manufacturer or seller and ask for technical support. First, locate the model of the unit, google it and see who is the original seller or manufacturer.

Then, contact them via email or phone and provide the model number and serial code. Usually, they help their customers and you may get your problems solved. If you don't have any receipt, claim that the system was passed to you by the previous owner. They may ask you for an ID which you should provide.
