Configuring JPEG and ActiveX Streams
JPEG webcasting and ActiveX webcasting are enabled together. The default Blue Iris home
page uses H.264 webcasting via an ActiveX component (you must answer "Yes" to install it
when you view the page remotely for the first time, and whenever the ActiveX component
version number changes).
When webcasting JPEG images, you may choose to scale them (make them smaller) and use a
specific quality value. By default, JPEG images are broadcast in the same size they are
captured according to the camera's video properties
(See 7.1). As you decrease image size and
lower image quality, the number of bytes needed for each image decrease as well. This
directly translates into smoother video (more frames per second), especially over slower
connections, or when bandwidth must be shared with multiple clients.
Advanced users may configure the H.264 stream via the Web Server (See 8.) options page.
Windows Media® Technologies
The Windows Media webcasting format intelligently compresses your camera's video stream
(and optionally the audio stream as well). The goal is simply to produce the highest quality
audio/video experience using the least amount of bandwidth. The advantages are fluid video
with audio for multiple viewers. The one clear disadvantage to this technology is that the
viewer (Windows Media Player® or a browser plug-in) "buffers" several seconds of the stream
before displaying the image, so the image is "delayed" by this amount of time. Another is
intensive CPU utilization to accomplish the encoding.
You should click the "Profile configuration" button to configure the Windows Media encoding
and broadcasting engine.
