Live view
Watch cameras in the live grid with sub-second latency.
The home page of CoreSight is the live grid — the operator's video wall in a browser.
The live grid
The grid shows multiple cameras at once as tiles, up to a 4×4 wall of 16 cameras. Pick which cameras fill the grid and the layout that suits your monitor. Each tile streams live video with the camera's name and status.
The navigation sidebar collapses to give the wall more room — useful on dedicated monitoring displays.
Low latency by default
Live streams use WebRTC, which delivers sub-second latency — what you see is essentially what the camera sees right now. If WebRTC cannot be established (a restrictive network between the browser and the box, for example), the player falls back to low-latency HLS automatically. The fallback is seamless; HLS adds a few seconds of delay but always works over plain HTTPS.
If tiles consistently show a few seconds of delay, the browser is likely on the HLS fallback. Check that UDP traffic between the operator workstation and the box is not blocked — WebRTC needs it for the sub-second path.
Codec handling
CoreSight plays H.264 streams directly. Cameras that send HEVC (H.265) or MPEG-4 are transcoded to H.264 on demand so they still play in the browser — no camera-side changes needed. Transcoding costs CPU on the box, so on large installations prefer configuring cameras to send H.264 where possible.
Per-tile actions
Each tile carries a footer with actions for that camera:
- Open the camera full-screen / focused view.
- PTZ controls on cameras that support pan-tilt-zoom, including presets (Cameras).
- Take a snapshot — a still JPEG of the current view.
- Jump to the camera's recordings (Playback).
The REC indicator
A red REC dot on a tile means that camera is actively recording right now. No dot means no recording is being written — if you expect recording, check the camera's recording mode and storage (Recording, Troubleshooting).
The indicator reflects actual recording activity, polled from the recorder — not just the configured mode — so it is a trustworthy "footage is being written" signal.
Camera status on tiles
Tiles reflect camera health: an offline camera shows its offline state instead of a frozen last frame, driven by the health watchdog's sub-30-second detection. Status is always paired with a glyph, not color alone, so it reads correctly on any monitor.
