The system also uses video motion detection, which looks for changes in video images (frames)
to detect motion. Video motion detection allows for motion detection beyond the range of the
PIR sensors and in extremely hot temperatures. Video motion detection is highly accurate, but
may trigger recording from changes in light or moving trees, leaves, etc. You can set the
sensitivity of video motion detection depending on your preferences
Please note that motion recording only starts when motion is detected. Because there is a slight
delay between when the motion occurs and when recording starts, quickly moving objects may
potentially be missed in the recording.

Q: Can I install the camera indoors looking out of a
window?
A:
No, this type of installation will affect the performance of the camera in the following ways:
When the night vision LEDs turn on, they will reflect off the glass, causing bright white
spots in the image.
