DUAL STREAMING IS REQUIRED FOR HTML VIEWING ARCHIVE
DUAL STREAMING IS REQUIRED FOR HTML VIEWING SOFTWARE

If recording is set to Motion + Low quality, only the Lo-Res stream will be archived if there is no motion, so Hi-Res stream will not always be available in archive.Ĭan be configured in Camera Settings > Recording.Ĭontrols the image quality of the High-Res stream for live and archive playback.Īffects secondary stream quality. Can be configured in Camera Settings > Motion. Specifies if the server detects motion on a given camera.

Note that some settings may be unavailable for certain cameras. If not, there are several settings that can be used to adjust stream processing.

Settings that are responsible for server motion detection, archiving and playbackĭefault software settings should work fine with most of the cameras. This behavior can be modified (see below). In these cases the Wisenet WAVE VMS Server will perform motion detection on the available stream that has the lowest resolution, as long as that stream is below 1024 x768. provide a Lo-res stream as Primary and Hi-Res stream as Secondary.do not support such settings, provide a Lo-Res stream with resolution higher than 640x360p.If specific settings are applied, server may or may not archive Hi-Res or Lo-Res streams (see below).Įven though Wisenet WAVE VMS requests and tries to configure the Lo-Res stream at or near 640x360 resolution at 7fps, some cameras may not comply, usually for one of these reasons:

If CPU usage is too high (too many streams opened, or fast forward/rewind is used), the client switches to Lo-Res display until CPU usage is low enough to decode all the streams displayed in client.If bandwidth between c lient and server is insufficient, the client switches to display Lo-Res to save bandwidth.Both streams are recorded to archive unless a different behavior is specified (see below).Ĭlient : the stream is selected automatically when viewing live or archive video: Server : the low resolution stream is used to do software motion detection and to preserve CPU and network. Why is Dual Streaming important how does it work? If a camera supports dual-streaming, Wisenet WAVE VMS requests two data streams (high‑resolution and low‑resolution) and uses them to save CPU and bandwidth usage. Secondary (Low-resolution) streams require far less computing power than typical high-resolution streams but provide much lower image resolution, at a slower frame rate.Primary (High-resolution) streams provide better quality image display but require significant CPU and network bandwidth to view.Most IP cameras can provide multiple data streams, each at a different resolution and frame rate.
