Specifications

The H.264 encoding objective may be either Constant quality (typically used for recording;

uses a variable bitrate or VBR) or Average bitrate (used to limit bandwidth as over a network

connection). A quality setting of 100% is considered "lossless" but will use an unbounded

amount of bandwidth.

You may also select a maximum keyframe interval, known as the Group of Pictures or

GOP. When streaming, using a higher value is acceptable as it raises the quality/bandwidth

equation. When recording, however, this value directly affects file seeking (random access)

times and efficiency and should be kept relatively low at the expense of using additional

storage resources. B-frames offer further advanced compression technology again best suited

for streaming.

If you use the Allow directory listing option, web users will be able to view the list of files in

your Blue Iris web root folder if you don't have a home page. You may also use this feature to

directly access your New and Stored clips folders. To do this, add /clips/ or /stored/

respectively to your URL, for example, http://mydomain.dyndns.org/clips/. Note that the

trailing / is required.

You may have Blue Iris alert you when a viewer has connected by playing a sound. The default

file plays a "pop" sound. Note that a "connection" is not the same as a "login." A connection

may mean that someone was presented with a login page.

If you choose to enable Authentication, Blue Iris will automatically cause remote users'

browsers to prompt them for a username and password. If they do not match what you

specify, they will be denied access. The connections status

(See 9.) page will show which

username was used to authenticate. Users are configured on the Options/Users (See 11.)
