observed under stress conditions, however, and I will work with the XVID development
team in an effort to solve this, as I believe this codec is ideal for this application to
replace the older and unsupported MP42 codec.
Support for the Gadspot 4000 and 4600 IP cameras with MPEG4 streams. Requirements
are that XVID is installed (xvid.org
) and the camera is using the newer firmware (no
"new prediction" in the video stream).
The motion sensor now attempts to discriminate between real motion and "scene
changes" (perhaps the camera has switched from day to night mode).

The motion sensor (See 7.3) now supports seven profiles. Each profile consists of a
completely separate configuration for the motion sensor. That is, each profile may have
its own sensitivity and other settings. The particular profile that is active at any given
time is determined by settings on the camera's
Camera Properties - Timer page. This
feature allows you to implement a different motion sensor configuration based on the
time of day and the day of the week.
It appears that Microsoft has applied patches to its implementation of Video for
Windows on Vista, so the AVI file format is once again supported in Blue Iris for Vista
users. Before using AVI with Blue Iris on Vista, please make sure you have applied all of
the latest updates and patches to Vista.
You now have much more control over the video compression used by the ActiveX
control for webcasting. New controls have been added to the Web Server
(See 8.)
options page to configure the video codec. If you have the XVID codec installed on your
system (available from
www.xvid.org) you may use this in place of the default MP42
codec. The XVID codec may be more stable for multi-viewer scenarios, whereas the
MP42 codec will be limited to a single viewer at a time.
You now have much more control over the video compression used for recording clips
(See 7.4). You may choose to use XVID, MP42 or the default MJPG. However, at this
time, the only recommended codec for recording is MJPG due to issues with recording
from multiple cameras simultaneously using either of the 2 other codecs (XVID
occasionally creates corrupt frames, sometimes crashing the de-compressor when clips
are replayed, and MP42, which sometimes crashes during compression of multiple
streams). It remains, however, that if you are recording a non-standard video size (such
as 360x240 or 640x400, etc), MJPG may not be able to handle that. XVID may, however,
be a viable option if you are recording from a single camera, or may work better under
XP than Vista, etc., so you should experiment with your particular configuration to
determine which codec will work best for you.
When recording clips in either MP42 or XVID format, you may select the keyframe
interval, which allows for inter-frame compression, greatly reducing the size of your
recorded files. For the previous MP42 behavior (every frame is a keyframe) use '0' as
