# Edit Nvr

`PUT /nvrs/{nvr_id}`

## Request

- Base URL: `https://api.verdun.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.verdun.ai/nvrs/{nvr_id}`
- Auth: HTTP bearer

## Path parameters

- `nvr_id` string, required

## Request body

- EditNvrRequest
  - `name` string, required: Display name for this NVR.
  - `host` string, required: Hostname or IP of the NVR's media server (DW Spectrum / Nx), Open Network Bridge (Milestone XProtect), or ISAPI web server (Hikvision / LTS / HiLook).
  - `port` string, nullable: Control port Verdun connects to. Vendor-specific — omit to use the vendor default for this NVR's kind: 7001 for DW Spectrum / Nx (media server: REST API + RTSP relay), 580 for Milestone XProtect (Open Network Bridge ONVIF port; RTSP on 554 is discovered via GetStreamUri, not configured here), 80 for Hikvision / LTS / HiLook (ISAPI HTTP port; 443 and 8443 are treated as HTTPS).
  - `rtsp_port` string, nullable: Hikvision / LTS / HiLook only: the TCP port Verdun reaches the NVR's RTSP service on. Omit to keep the stored value. Ignored for other NVR kinds.
  - `username` string, required: NVR service-account username.
  - `password` string, nullable: New service-account password; omit to keep the stored one.
