Viewerframe Mode Refresh primarily refers to a specific streaming mode used by network IP cameras (notably legacy Panasonic and Axis models) to display live video through a web browser. In this mode, the camera serves individual JPEG images that are continuously refreshed to simulate video, which is highly compatible across different web browsers and consumes less bandwidth than Motion-JPEG. Key Features of "Viewerframe Mode Refresh" Cameras
Rule of Thumb: The I-frame interval should be a multiple of the frame rate (e.g., if FPS is 20, set the I-frame interval to 40 for a full refresh every 2 seconds).
- Hard Refresh (
force=true): Bypasses browser/memory cache. Use after source asset changes. - Soft Refresh (
force=false): Re-renders current cached data. Use after UI resize or mode toggle.
: It is less taxing on the camera's processor than encoding high-definition video for multiple users. HTML embed code to place this camera feed onto a private webpage?
// Optimal sequence to avoid frame drops
viewer.setMode('aspect-fit');
viewer.refresh( preserveZoom: true, force: false );
