Overview

The Live View page provides real-time monitoring with up to 16 simultaneous cells (4×4), plus wide and spotlight presets, drag-and-drop camera assignment, saved views, and PTZ control.

Access Live View from Video → Live in the top navigation.

Grid Layouts

Use the grid selector toolbar to choose how many cameras to display simultaneously:

Layout	Cameras	Best for
1×1	1	Full-screen focus on a single camera
2×2	4	Small deployments or a focused area
3×3	9	Mid-size deployments
4×4	16	Standard multi-camera monitoring

Adding Cameras to the Grid

The left sidebar shows the Device Tree — a searchable list of all cameras organized by device group. To add a camera to the grid:

Drag and drop a camera from the device tree onto any empty cell.
Double-click a camera in the device tree to place it in the next empty cell.
Right-click a grid cell to select a specific camera from a dropdown.

To remove a camera from a cell, right-click the cell and select Remove Camera, or drag another camera onto the same cell to replace it.

Streaming Modes

Kalytera receives the camera's RTSP stream at the server and delivers browser-compatible media through a server-mediated path. It selects between these viewing technologies based on browser, network, and camera-profile compatibility:

WebRTC (preferred): Low-latency browser live viewing suited to interactive monitoring and PTZ control.
HLS (fallback): Reliable browser fallback when WebRTC is unavailable for the current browser, network, or camera profile.

Right-click any camera cell to see which streaming mode is active (Info) and to force a switch between Main and Sub stream.

Saved Views

Save the current camera arrangement as a Saved View to restore it with a single click:

Arrange cameras in the grid as desired.
Click the Save View button in the toolbar (floppy disk icon).
Enter a name for the view and click Save.

Saved views appear in the Saved Views panel at the top left. Click any saved view to instantly restore that camera layout. Views can be shared across operators — all users see the same saved views.

Fullscreen Mode

Double-click any camera cell to enter fullscreen mode for that camera. Press Esc or double-click again to return to the grid. Use fullscreen for detailed inspection of a specific camera stream.

PTZ Control

For PTZ (Pan-Tilt-Zoom) cameras, a control overlay appears when you click a camera cell in the grid. Use the on-screen directional buttons or scroll the mouse wheel to zoom in and out. PTZ control works best over WebRTC streams (lowest latency) — if your camera falls back to HLS, there will be noticeable delay between command and movement.

PTZ control requires the camera to support ONVIF PTZ or a native SDK. Check the camera's specifications if PTZ controls don't appear.

Tips and Best Practices

Use the substream (lower resolution) when displaying many cameras in a large grid — it reduces server and network load significantly without losing useful monitoring detail.
Create Saved Views for different shifts or monitoring scenarios (e.g., "Night Watch — Perimeter" vs. "Day — Entrance & Lobby").
Use device groups (created in Configure → Devices) to organize cameras by location, building, or floor for easier navigation in the device tree.
If a camera shows a spinner or blank cell, check Health Monitoring for the device's stream health score and recent error history.
