Monitors

The Monitors screen lists all cameras configured on your ZoneMinder server. Each monitor is shown as a card with a live snapshot and status.

Monitor Cards

Each card shows:

  • Live snapshot - A periodically refreshed image from the camera

  • Monitor name - The name configured in ZoneMinder

  • Function - The current monitoring mode (Monitor, Modect, Record, etc.)

  • Status - Whether the monitor is online, in alarm, or offline

  • Event count - Number of recent events

Tap a card to open the Monitor Detail view.

On desktop, hovering a monitor card for a moment opens a larger (400px wide) live preview next to the card. The preview uses its own streaming connection that is opened when the preview appears and closed the moment your cursor leaves. The underlying card remains clickable while the preview is visible.

Filtering Monitors

Use the Groups selector at the top of the screen to filter by ZoneMinder monitor group. The selection persists across navigation within the same session.

To remove a monitor from this list (and from the Events and Timeline views) for the current profile, hide it from the Hidden Monitors section in Settings.

Monitor Detail

The detail view for a single monitor includes:

Live View

A continuous live stream from the camera. The Monitor Detail page always streams, the global Streaming Mode setting (Streaming/Snapshot) does not apply here. The connection is closed (CMD_QUIT sent to ZoneMinder) when you leave the page.

The actual transport depends on your server:

  • Go2RTC streaming: used when Go2RTC is configured on your server and enabled for the monitor. The app tries WebRTC, MSE, and HLS in parallel and uses whichever produces video first.

    • WebRTC (lowest latency)

    • MSE (Media Source Extensions)

    • HLS (HTTP Live Streaming)

  • MJPEG streaming: used when Go2RTC is disabled, unsupported, or fails. Continuous Motion JPEG via ZoneMinder’s ZMS.

If Go2RTC connects but no video frames appear within 8 seconds, the app automatically falls back to MJPEG. Monitors that fail Go2RTC are cached for 5 minutes before the app retries Go2RTC on them.

The protocol label (enabled in Settings) shows which streaming protocol is active on each feed. The Monitor Detail page also shows native video controls (play, pause, volume) for Go2RTC streams.

For tile views (Monitors list, Montage, Dashboard widgets), the Streaming Mode setting does apply, see Settings for details.

Per-Monitor Override

You can force MJPEG for individual monitors via the monitor’s Settings dialog (Video tab). When Go2RTC is enabled for a monitor, a toggle appears to turn it off for that monitor only. See Settings for details.

PTZ Controls

If the monitor has PTZ (Pan-Tilt-Zoom) configured in ZoneMinder, directional controls appear below the live view. Use these to pan, tilt, and zoom the camera.

Recent Events

A list of recent events for this specific monitor, with thumbnails and timestamps.

Monitor Info

Technical details about the monitor configuration (resolution, source type, function, etc.).
