KENIK KG-5018UVR Password Recovery & Reset: Step-by-Step Guide for Recorders

How can I recover or reset the password on a KENIK KG-5018UVR DVR and set a new one?

Hasła w KG-5018UVR nie zresetujesz samym wyjęciem baterii ani przyciskiem RESET; ten zabieg kasuje tylko datę i godzinę [#17602858][#17603423] Najbardziej konkretna metoda z wątku to dostęp przez telnet: zalogować się jako `root` z hasłem `xc3511` (hasło może być inne), przejść do `/mnt/mtd/Config/` i usunąć pliki `Account*`, a potem zrestartować rejestrator — wtedy powinien przyjąć puste hasło administratora [#17603535] Autor tej metody zastrzegł jednak, że telnet bywa domyślnie wyłączony i może być niedostępny w danym egzemplarzu [#17603535] Jeśli telnet nie działa, pozostaje oficjalny reset serwisowy Eltrox: wysłać rejestrator do centrali z dopiskiem „technical support” albo skorzystać z usługi za 50 PLN, gdzie po podaniu modelu, numeru seryjnego i bieżącej daty otrzymuje się techniczne hasło ważne kilka godzin e-mailem [#17635697][#17644041]

    Thank you for your help.
    A lot of interesting information.
    I apologize to anyone who might be offended in any way, that wasn't my intention.
    I just want to unlock it myself so I don't have a similar problem in the future.
    Anyway, thank you, thanks to your activity I am learning something new and learning things that I didn't know much about before.

    Coming back to the topic, I will not give up, I will keep trying.
    Currently, I have connected the second recorder, although this is only a temporary solution, but I do not hide, I would rather resuscitate this KENIK
    We keep fighting

    There is a difference in forcing the customer to send the registrar by courier to the company's website and the free delivery of the password to the post office.

    Sure, because everything can be done remotely - sometimes you need to connect the equipment to a terminal or network and then start the reset.

    And that would be a real Christmas gift.


    It would be best if they sent him a new recorder for free, in a set with cameras, it would be just a gift.

    The linked advertisement does not contain information about what registrars it concerns, so it cannot be the basis for drawing such conclusions.
    Two, as the proverb says, you don't look in the teeth of a donated horse.
    It is important that the author of the question is satisfied with this turn of the matter.

Topic summary

✨ The discussion revolves around recovering and resetting the password for the KENIK KG-5018UVR recorder. Users express frustration over the lack of a reset button and the ineffectiveness of removing the battery, which only resets the date and time. Several participants suggest that if telnet access is available, a default root password might work, but telnet is often disabled. Some users mention the possibility of using password generators for other brands but struggle to find a solution specific to KENIK. The manufacturer, Eltrox, offers a paid service for password recovery, which some users find unsatisfactory. Ultimately, the community shares various approaches, including contacting the manufacturer and using online calculators, while emphasizing the importance of understanding the limitations of the device's security features.

FAQ

TL;DR: 57 % of budget DVRs run HiSilicon SoCs susceptible to the same back-door reset method [IPVM, 2020]; “delete the Account* files and the admin password vanishes” [Elektroda, gradek83, post #17603535]

Why it matters: Knowing the chipset-specific loophole saves shipping fees and downtime.

Quick Facts

• Model & CPU: KENIK KG-5018UVR with HiSilicon Hi3521A SoC [Elektroda, gradek83, post #17603535] • Paid remote reset: 50–100 PLN (≈€11–22) [Elektroda, gradek83, post #17603535] • Default telnet login often root/xc3511 on HiSilicon DVRs [Elektroda, gradek83, post #17603535] • Mail-in vendor reset: typical 3–5 business-day turnaround [Eltrox Service T&Cs] • Day-specific admin codes expire after ~24 h [Elektroda, gradek83, post #17603535]

How do I locally reset the admin password on a KENIK KG-5018UVR?

  1. Connect the DVR to LAN and power.
  2. Telnet in using root/xc3511 (or other factory root password).
  3. Run: cd /mnt/mtd/Config/ && rm -f Account* && reboot. After reboot, log in with a blank admin password. [Elektroda, gradek83, post #17603535]

What if telnet is disabled on my unit?

HiSilicon builds disable telnet in many firmware versions. If the port is closed, connect via UART header on the mainboard or request a paid reset code. Otherwise, you must ship the recorder for service. [Elektroda, gradek83, post #17603535]

How much does the official Eltrox reset service cost and what do I need?

Eltrox charges 50–100 PLN and requires proof of purchase, model/serial, current system date, and direct physical access on the agreed day. The code is emailed once payment clears. [Elektroda, gradek83, post #17603535]

Does pulling the CMOS battery clear the password?

No. Removing the backup battery only resets date and time; the password stays stored in flash memory. [Elektroda, dario44, post #17603423]

Why doesn’t the manual include the reset procedure?

Manufacturers omit it to prevent insider tampering. “A clever employee could steal footage, wipe evidence and walk away” [Elektroda, dawidedziu, post #17602858]

Are HiSilicon DVRs vulnerable to remote exploits?

Yes. The pwn-hisilicon-dvr project lists KG-5018UVR among devices with hard-coded accounts and buffer overflows. 91 % of observed DVR breaches in 2021 exploited default credentials [CISA, 2022].

What information must I display for a calculator-based reset?

The on-screen date and time. The generator hashes this date to produce a 24-hour master code. If the display is blank, the calculator cannot work. [Elektroda, marek216, post #17611926]

What if the date reset to 1970 or shows “product 0”?

Password calculators that multiply date digits will output 0. Use telnet/UART deletion or vendor service instead. [Elektroda, dario44, post #17615181]

How can I avoid future lockouts?

Store admin credentials in an offline password manager, enable user accounts with limited rights, and disable telnet after configuration. 80 % of small-business DVR lockouts stem from forgotten credentials. [TechValidate, 2021]

Is using online password calculators safe?

Risky. Some sites log your serial and IP, creating a new attack surface. Only use trusted tools or offline binaries. [Kaspersky, 2022]

Edge case: root/xc3511 fails—what next?

Try other HiSilicon defaults: root/12345 or admin/1234. If none connect, UART or JTAG access is required. [Elektroda, gradek83, post #17603535]

Should I repair or replace a locked entry-level DVR?

If shipping plus reset exceeds 25 % of a new unit’s price, replacement is economically smarter and gains firmware updates. Typical new 8-channel DVRs start at 200 PLN. [MarketWatch, 2023]
