1. Executive Summary

This report addresses the default password configuration for the Annke DN81R Digital Video Recorder (DVR). The purpose of this assessment is to identify the factory default credentials, evaluate the security risks associated with unchanged default passwords, and provide actionable recommendations for securing the device against unauthorized access.

The Default Login for Annke DN81R

For the Annke DN81R model (and most Annke DVRs/NVRs manufactured after 2018), the factory default credentials are:

• Username: admin
• Password: 12345 (or left blank on very old firmware)

Note: Some firmware versions may require you to create a password during the initial setup wizard. In that case, there is no universal default—you must use the password you set.

Q: Can I recover footage after a reset?

A: No. A factory reset formats the hard drive. Remove the hard drive and connect it to a PC with recovery software before resetting if the footage is critical.
