Design & Manufacture
All made in Taiwan
Optional Function: build-in ADAS to
CH5
Advanced Driver Assistance Systems (ADAS) uses a
specially selected 720P camera mounted in the center of the front
windshield, working with GPS or vehicle speed lines, and left and
right direction light trigger lines, using image recognition
technology to judge car driving behavior, warning in advance of
possible dangerous conditions, allowing drivers to take early
measures to avoid traffic accidents.
The ADAS system includes a Lane Departure Warning System and a Front
Collision Warning System. When the vehicle speed reaches 50Km/Hr or
more, it will automatically start to instantly recognize the lane
line range and the distance of the vehicle in front. Deviation
warning is issued when the driver deviates from the lane and the
driver does not apply the corresponding direction light. In addition
to the warning symbol on the screen, a three-second long tone is
given to the driver; or three short beeps are issued if the vehicle
in front is detected to be within 30 meters.
The dedicated camera must be connected to the fifth channel (CH5) of
the PS-881 to function, and also this channel can not be set to flip
or mirror, otherwise it will not work properly.
The ADAS function is independent operation. As long as the ADAS
function is turned on, even if the recording is stopped, or there is
no SD card, or during the playback of the recorded files or in menu
operation, the ADAS will continue to work, and the LDW or FCW will
still be prompted. Note: if it is in the playback mode or menu
operation, there is only a beep tone prompt. If it is in the
recording state, the warning symbol of LDW or FCW will be displayed
on the fifth channel (CH5) screen of the video at the same time, and
the warning symbols at that time can be viewed when the recorded
files are playeback.
