• Reassemble and power on the DVR.
  • Upon boot, the DVR will revert to factory defaults. Now try admin / dn81r.
  • Alternative soft reset (if you can access the menu but forgot password):
    On the local monitor, go to System > Maintenance > Default > Factory Reset. You may need the current password to proceed.


    If you are adding the DVR to the Annke Vision app (or older Annke Lite app), the device might require the dn81r password as the "Device Password" field.

    If admin or 123456 does not work, the device has likely been configured previously. DVRs "lock" the default password once a new one is set.

    Common scenarios:

    Annke has changed its default login practices over the last decade. Below is a breakdown by firmware generation.

    If you have recently purchased an Annke security DVR (Digital Video Recorder) or are troubleshooting an older model, you have likely encountered the cryptic string of characters: dn81r. This is not random gibberish; it is the factory-set default password for a significant number of Annke DVR models.

    However, relying on the "dn81r" password can lead to confusion, lockouts, and serious security risks. In this comprehensive guide, we will explore everything you need to know about the Annke default password dn81r, including how to use it, why it might fail, how to reset your device, and how to protect your surveillance system from hackers.


    Once you log in with dn81r, immediately change it. Here’s how:

    First, a crucial clarification: DN81R is not a password on modern Annke DVRs. This is the most common misconception.

    In reality, DN81R is typically a default device name or a network hostname assigned to certain older Annke DVR models (specifically those based on H.264 compression technology). When users see "DN81R" on their network scanner, router’s DHCP client list, or the DVR’s on-screen display, they mistakenly assume it is a password. It is not.

    The actual default password for these units is almost always something else—usually blank, 12345, or admin.

    Hackers maintain databases of default passwords for DVRs, routers, and IoT devices. dn81r is publicly listed on exploit databases (e.g., defaultpassword.com, cirt.net). A simple Shodan.io search can reveal hundreds of Annke DVRs still using dn81r, allowing anyone to view, mute, or delete your security footage.
