I have a H.264 Network DVR installed at my premise but one of my employees changed the password and can't remember it. How can I tried the option of removing the battery but it did not work. How can I reset my password.

which in some resets it to the default pass, in others it may just allow you to change it i'm not sure. I used it (for mine it was calculate_2.exe file to reset) and then my pass went to blank after a reset and i was in

Came here hoping that one of the calculators posted by LordFox would work on my Amcrest IP camera. It decided to randomly stop accepting my pass. I didn't forget my pass either, i guess it got corrupted somehow as the pass was saved on my browser, phone app, and PC app and all were denied.

Similar to computers, each main-board of DVR/NVR devices has a 3V button battery. Some people may naively think by short-circuiting or taking battery out will reset the DVR/NVR. However, doing this only reset the date and time of your device, it will not reset the password. On contrary, password and settings are stored in flash memory.

dvrcms is a free blog attempt to provide information about security camera systems, burglar alarm and equipment, review, troubleshooting, installation, commissioning, password reset, software upgrade and new technologies.

1. Use the DVR factory default password2. Use a DVR password generator 3. Update the firmware and reset the DVR4. Reset the DVR by removing the battery5. DVR physical reset with jumpers6. Delete the password file by using telnet

If your DVR has the internal chip manufactured by Hisilicon, there is a great chance that the DVR password generator will work, depending on the model and year it was manufactured. See the chart below:

There are cases where the DVR has an unknown brand, this happens a lot with Chinese models that are manufactured without a brand and sold to third parties that use a name like H.264 DVR for example.

Important: The fact that your DVR is named as H.264 DVR or something similar does not guarantee that the software will work, as explained above, this is a generic name given by the distributor who purchased an unbranded Chinese DVR to resell to the customers.

There is also an Excel spreadsheet that can generate passwords for DVRs, it works the same way, just put the current date and look at the result in the yellow cell, it works only for dates after the year 2000.

The manufacturer provides firmware so that customers can update the equipment for better security and new features, in most cases these updates do not delete the existing password nor reset the DVR, however in specific rare cases the firmware update can reset to the factory default.

If the manufacturer has this option available, you can download a file from a website and put it on a pen drive that should be connected to the DVR, after restart the equipment it will read the contents of the pen drive, update the firmware and reset the password to factory default.

What happens is that the DVR runs out of battery for a while and goes back to the factory default date, such as 1/1/2000 for example, so you can use the DVR password generator to create a new passwords based on this date.

For this type of reset it is necessary to open the equipment and physically close the contacts of two specific pins. That work for some Swann DVR models that have some jumpers for DVR reset.

1. With tweezers close the contact between the pins2. Turn on the DVR and wait until you hear a beep.3. Remove the tweezers while the DVR is still on4. Wait until the DVR restarts5. Use the admin/username and password to log in

This process works with DVRs that have a chip manufactured by a Chinese company that accepts a Telnet connection with a standard XC3511 password. Some models known to have this chip are the H264 DVRs:

If your DVR has the login screen like this below, it indicates that it uses this type of chip that accepts the connection via telnet, no matter if the brand is, the internal chip is from the same manufacturer.

Since this command window will be able to communicate with the DVR, it will respond by asking for username and password and then after entering this information, you will have access to the operating system and will be able to view the files in the directories and folders and also remove them.

Thanx for the password generator, it worked on my conceptronic, however there is a tab system login > system info

with a few tabs like audio in, alarm in, remote control, enable rs232, a few other options and below that a box checked maintenance functions. this one is checked. Thats locked the dvr functions. it needs a different password.

DVR reset using telnet

Way working well .. Thank you so much giving this valuable Idea.. and I so little mistake there is no write down by text, change directory (cd Config) part.. But It Have On the Dos Command Image.. So Its Happy to sow that. so my dvr remove all unknown Password. now I can log to my DVR.

It is very necessary for us to have the backup dump of that DVR to restore it to normal condition. So, here are some backup dump files of Digital Video Recorder firmware for free Download to support the technicians. Download free Bios Bin files. If you are facing some issues during software installation then read here first.

All software files are saved from working DVRs with the help of the Programming tool and can be loaded or written by the programmer. These firmware files may not support the USB upgrade method. If you are not a technician then do not try to update. Kazmi Elecom Team is not responsible for any type of damage/loss as a result of uploading/Installing the firmware.
