Safety Advice
CAUTION
Damages due to production malfunction, loss of data, or other damages occurring
while using this product shall not be the responsibility of the manufacturer. Although
the product is a device used for recording videos, the product may not save all videos
in the case of a malfunction. In the case of an accident, the sensor may not recognize
the shock when the impact is light and as a result, it may not begin recording
automatically.
CAUTION
Install the product where it does not block driver’s visibility and where there is
no airbag installed. This could cause an accident or might injure the passengers in
case of accident.
CAUTION
Connect your vehicle’s power cable to the product after starting the vehicle.
The instant over voltage generated when starting up the vehicle may damage
the product if it is already connected.
SAFETY ADVICE
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER.
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL
.
WARNING:
TO PREVENT FIRE OR ELECTRIC SHOCK HAZARD,
DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
Please make sure you follow the safety advice/instructions given in the user guide.

DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
Battery for RTC (Real Time Clock) inside.

6
Situations where reception may be obstructed.
1.
Activate the product in an area without large buildings to improve GPS
reception.
2. The temperature range for optimum operation of the GPS receiver in
your car is -10 ~ 50°C.
3. When using the product for the first time or after a long period (more
than three days), it may take a little longer to recognize your current
location.

The commercial purpose GPS has the average range error of more than 15
meters and the range error could be more than 100 meters due to
environmental conditions like buildings, roadside trees etc.
GPS Reception
It may take between five and thirty minutes to get GPS reception.
1. If there is an object at the end of the GPS antenna
2. If your vehicle has metallic elements on the windshields
3. If equipment generating electromagnetic waves that interfere with the GPS
signal is installed in the vehicle, e.g. other GPS devices such as certain
types of wireless activated alarms, MP3, CD players, etc. using GPS.
4. If you are using a receiver connected by cable, electric interference can be
avoided by simply changing the location of the GPS receiver (antenna).
5. On heavily overcast or cloudy days, if the vehicle is in a covered location
such as under a bridge or raised roadway, in a tunnel, an underground
roadway or parking area, inside a building or surrounded by high-rise
buildings.
6. If GPS signal reception is poor, it may take longer to locate your current
position when the vehicle is moving than when it is stationary.

3. Product Applications
This product can be used for video surveillance or remote monitoring in vehicles such as
buses, logistic vehicles, trucks, long-distance coaches, taxis, tankers, cars, school buses,
police cars, patrol cars etc. In front-end it mainly collects video signal by dedicated
automotive camera, then transmits to the SVC420GPS-L/SVC820GPS-L host via a special
video cable to do the video compression and image processing, which is stored in the SD
card/HDD.
The unit can also be remotely monitored or remote video recorded and downloaded by the
remote client with 3G models. The user can locate the vehicle position in real time; Figure
1-1 schematic diagram is a common mode of application. Each function during actual use
will vary with the model number (For example. SVC420GPS-L - 4 Channel or SVC820GPS-L
– 8 Channel).
