Specifications

The Object detect/reject option (previously "blob detection") provides for more advanced

motion detection, and will be an integral part of motion tracking in a future release. After

analyzing the image for overall change, an additional algorithm is applied which attempts to

identify a region within the image where motion is occurring. If you have the overlay motion

map feature enabled, you will see this region represented by a red rectangle. It is the size of

the red rectangle that is compared against the Size sensitivity setting.

You should only use the Object detect/reject option when it is likely that there will be one

moving object in the view at a time. This is because the software analyzes object motion and

will reject motion that is not fluid enough in order to prevent false alarms. The algorithm will

only recognize motion that follows a vector, an important precursor to eventual PTZ tracking;

erratic object detection will be seen as noise.

By default, Blue Iris uses color and brightness changes to help detect motion. In certain

circumstances, such as low-light, this may be undesirable. Try setting the brightness/color

option to brightness only in low light conditions. If you are having trouble with shadows and

lighting changes such as cloud cover, try setting this option to color only.

If you are having trouble identifying the source of motion in your video, you may experiment

with the overlay motion map feature. This will cause each image to be overlaid with a

representation of the motion in that image. That is, what's changed from one frame to the

next will be shown with a blue overlay.

When triggered

The Break time slider allows you to choose the amount of time that the camera should remain

in the triggered state once it is initially set. This feature is analogous to the timer that's in your

motion-sensing outdoor flood light. Once you trigger the light, it remains on for a

programmed duration of time once motion has stopped. Just as with the light, as motion or

other trigger input continues, the timer is reset, and the camera will remain in the triggered

state.
