1. Overview NAPCO (National Patent Corporation) is a well-known manufacturer of security systems, including Digital Video Recorders (DVRs) often sold under the NAPCO Gemini series or as part of integrated security packages (e.g., with iSee Video). Like many legacy security devices, these DVRs ship with factory-default credentials. Failure to change these credentials during installation poses a significant security risk. 2. Common Default Credentials Based on technical documentation, user manuals, and incident response reports, the most widely used default login for NAPCO DVRs is:
| Field | Default Value | | :--- | :--- | | | admin | | Password | admin | | Port (HTTP) | 80 (or 9000 for some embedded web servers) | napco dvr default password
