Note that this details the process for the Jupiter v3 and Neptune. The previous Jupiter v2 has a different interface.

To set the motion settings follow the below:-
Go to Menu (button on front of your device or on the remote)
Select Andvance Config
Select Detection on the left
Select the Channel you wish to set Detection on
Change DET (for Detection) to ON to enable
Select Record on the left
Ensure Event Record Enable is set to ON
Set Event Record All Channel to ON to record all channels when an event occurs, or OFF to record only the channel the event occurs one
This completes the quick motion settings setup.

Notes on Record settings
Pre Alarm Record When pre-alarm and event recording functions are both activated, the DVR will record 8MB data before an alarm / motion event is triggered.

Notes on Detection zone settings
LS is Level of Sensitivity (00 High 15 Low)
SS is Spatial Sensitivity, number of grids (00 High 15 Low) Once an object moved through the set SS grids, it initiates the motion recording.
TS is Time Sensitivity (00 High 15 Low) This sets how long the object stays in the detection zone before triggering the motion detection
ALARM Select N.C (normal closed)/N.O (normal open) depending on your installation needs. The default alarm value is OFF.
AREA Here you can set the zone for detecting motion. There are 16 × 12 grids per camera for all channels. The marked Pink blocks represent the area that is not being detected while the transparent blocks are the area under detection.
