Motion Detection
Motion detection feature, if enabled, will trigger the IP camera to send the
snapshot/video clip to remote server (Email, FTP) or to record the event to local
storage.
How does motion detection in D-Link IP Camera works?
• D-Link IP Cameras that support motion detection feature allow three different areas to be
monitored for motion detection.
• Sensitivity and Percentage parameters must be defined in order for the motion detection of
the IP camera to work.

Day & Night Solution - Light
Light perception
• Light is a form of radiation wave energy that exists in a spectrum. The human
eye can see, however, only a portion (between wavelengths of ~400 – 700
nanometers or nm).
• The following illustration shows the wavelength where human eyes will not be
able to see: outside the range to the left of the BLUE color below 400nm is the
ultraviolet light, and outside the range to the right of the RED color above 700nm
is the infrared light.
