Rust Motion

Detects motion in the camera picture with low load on the processor. It also catches small and slow movement.

What it does

• Detects motion in the camera picture and marks the areas where something moves
• Puts little load on the processor and needs no graphics card
• Detects small and slow movement reliably, by day and at night
• Counts changed regions close to each other as one movement, so a distant animal is one detection instead of several specks
• Starts over after a camera move or a sudden change of exposure instead of marking the whole picture
• Keeps separate settings for each camera, with a button that restores the default values

What you need

• The detector is not available for every server system. If it is missing for yours, the plugin adds no motion sensor to the cameras

Settings

• Area: the minimum combined size of nearby changed regions that counts as motion
• Threshold: the brightness change at which a pixel counts as changed
• Blur Radius: smooths the picture before detection to reduce noise
• Dilation Size: joins nearby changed pixels into one area
• Reference Hold: how many seconds the comparison image is kept. Higher values catch very slow movement, lower values keep the motion boxes closer to the current position
