RECORDING BASICS
Automatic/Manual Recording
You can set the DC4 to start recording when the vechicle’s engine
turns on, or you can turn o that funcon and begin record
manually. Go through the Menu system (Menu/Function Settings/
Automatic Recording) to turn this funcon ON or OFF.
Emergency Recording
At any given me, you may come across a situaon such as an
accident where you want to start recording. Press to start
emergency recording if you are already recording. (Press twice
if you are not already recording.) The DC4 saves emergency les in

10
the microSD card’s Emergency folder. The Emergency folder only
holds 10 emergency les, regardless of the le size. If there are 10
emergency les saved, any new emergency le records over the
oldest emergency le.
Collision Detection
You can determine how strong a collision needs to be for automac
collision recording to start. Set the G-Sensor level in Menu/
Function Settings/Collision Detection. The device saves the
currently recording le to the Emergency folder as an emergency
le.
Collision Detecon applies to vehicles that are moving. It does not
apply to vehicles in Parking mode, where the vehicle’s engine is
turned o and Parking mode is acve.
Parking Mode
Parking mode lets you set recording parameters for a parked car
(Menu/Function Settings/Parking Mode). The Parking Mode
menu provides 3 opons:
• O. Turns o Parking mode so that no recordings are triggered.
• Collision Recording. Select this to allow collision recording for the
parked vehicle. Files are saved as video les in the Video folder.
• Moon Detecon. Select this to allow moon detecon for the parked
vehicle. Files are saved as video les in the Video folder. Aer the
vehicle engine stops (turned o), the device begins recording at that
point regardles of whether or not moon is detected. Recording stops
aer about 10 seconds and the le becomes a reference to moon
detecon.
