Motion Detection & Recording Setup Setting up motion detection and email alerts
In plain English: Threshold is the difference between a car driving quickly by on a street
and a car driving into the field of view, slowing down, and turning into a driveway. The car
driving past would not trigger motion detection based on a certain threshold setting, but
the parking car would trigger motion detection with that same threshold setting. The
higher the threshold, the more time motion needs to occur before motion detection is
triggered. The lower the threshold, the less time motion needs to occur before motion
detection is triggered.
If sensitivity is set to 100 and threshold to 0, motion detection will be triggered most
easily by almost any change in the field of view, large or small. But if sensitivity is set to 0
and threshold to 100, motion detection will be extremely difficult to trigger.
The four regions are all different colors so you can customize the field of view of any
camera to your highly specific preferences.
To choose another region, hover your mouse pointer near the top-center of the
5.
region window, and a small window will appear. Keep your mouse pointer inside that
small window and select either region 2, 3, or 4:
You will be able to click individual blocks or click-and-drag an area with the new selected
color to highlight portions of the screen. Each new region (or color) has its own unique
sensitivity and threshold settings. The different regions/colors can also overlap one
another.
