Specifications

• Compiled with a newer version of the AAC audio encoder for MPEG4 files as well as an

updated H.264 decoder. Bugs fixed related to bit rate-limited encoding.

3.08 - August 8, 2012

• Major enhancements have been made to the motion detection camera properties (See

7.3) page as well as to the underlying motion detection algorithms. It should now be

much easier to visualize and understand the effects of the various sensitivity settings.

• My apologies, but it may be necessary once again for you to evaluate the effects of the

sensitivity and object detect/reject (previously "blob") settings. The goal of changes

made to these settings and algorithms continues to be the reduction of false alarms and

the enhancement of legitimate motion detection.

• A single instance of motion beyond the sensitivity thresholds while triggered is now

adequate to continue the trigger. Previously, an additional "make time" period of

motion was required, which would have made it more difficult to extend the trigger

period.

• The object detect/reject feature now uses an algorithm to only recognize motion that

follows a vector, an important precursor to eventual PTZ tracking. Erratic object

detection will be seen as noise.

3.07 - July 13, 2012

• A new Framerate limiting compatibility mode may be enabled from the Video tab's

Network IP camera configuration page

(See 7.1). Only use this mode if you are unable

to control the FPS and/or bandwidth that your camera is producing and you need to find

a way to lower the CPU requirements of the full stream. When this mode is enabled,

Blue Iris will attempt to meter and refuse incoming data, limiting the number of frames

processed to the setting on the Video tab. This may setup a buffering situation within

the camera itself, causing a delay in the video stream. If at all possible, it is better to

have the camera limit what it is sending as opposed to having Blue Iris limit what it will

accept.

• Important updates to the motion detection algorithm to further enhance detection in

low-contrast situations. The contrast slider on the camera properties/triggers

(See 7.3)

page has a new range and default value. When considering motion, you may now

choose to process brightness only, color only, or by default, both. Brightness only may

be better for low-light situations, while color only may be best at negating the effect of

lighting changes and shadows.

• Important updates to the network IP camera streaming code to enhance performance.
