You can set AMD motion detection for a maximum of four channels. It requires recording a profile setting of a minimum
`
10fps. It is recommended you use 30fps with a resolution of less than 2M. (If the recording profile's fps is out of range, the
AMD motion detection function will not operate normally.)
It is recommended you install or set a camera so that the size of a recorded object is within the range below.
`
- Minimum Detection Size : More than 1/4 of a single lattice area
- Maximum Detection Size : Less than 1/4 of the full screen
If you set the camera location to <Outdoor> then the car/human classification function will operate. If you set it to
`
<Indoor>, the heat map cannot display the detection result for cars. Heat map data will be saved in 30 seconds after you
set AMD motion detection.
For more on heat maps, refer to "Heat Map Search". (Page 94)
If the video has low intensity or is fuzzy, it is recommended to set the sensitivity to <High> and if the video has a dynamic
`
background (shaking tree, wave) then it is recommended to set it to <Low>.
