2.7 Observer Transcoding™ for low-bandwidth client-server connections (ABS)
The unique Observer Transcoding™ technology (also called ABS for adaptive balanced streaming)
reduces the necessary bandwidth for video streams to a fraction of the usual values. Especially high-
resolution cameras can thus be streamed from server to clients over low-bandwidth wide area
network (WAN) connections without loss of quality. Therefore even megapixel cameras can be
operated over very low bandwidth connections that would normally prevent their operation. The
technology works for all cameras, streaming resolutions, and formats (including MPEG-4, H.264, and
MxPEG).
Additional CPU resources are needed at the server and at the client for transcoding streams.
Transcoding™ can be set up in the server level by limiting bandwidth for live video and recording
playback streams as well as for recording exports (see
11.2 Setting Observer server parameters
on page
110).
