Limited Warranty
Genie grants a warranty of this product for 18 months. Please offer the purchase date and the serial number of
the Bar-code on the back of the product to your distributor or retailer as a proof for this purpose. During
the warranty period, in case of defects in material or workmanship, thedefective unit will be repaired or replaced
according to the assessment of Genie.
However, this warranty does not cover damages caused byimproper use nor from unauthorized modifications by
third parties.
Patents
The patents that cover design, operation, techniques, and unique features of a single-cable transmission device
for a surveillance system are still pending.
System Description
The RU and the LU are to be installed in different locations. In addition, the RU is required to offer a huge amount
of power. So please refer to pages 4 and 5 for their different operating temperatures. The ambient
storage temperature is from -30°C to 75°C and the relative humidity is from 20% to 90%. Remember that both the
RU and the LU need to be kept somewhere well ventilated.
Please be informed that the allowable maximum DC resistance of the coaxial cable between the Sender Unit and
the Viewer Unit varies with the difference of current and voltage consumption of the camera. Please see
the table below for more information.
Further Description of VDS4020
•
Designed for surveillance IP cameras for long distance transmission.
•
Transmits IP duplex signals up to 800 meters away and sends PoE power to the cameras through a coaxial
cable as opposed to Ethernet UTP Cat6 cable which transfers signals for only 100 meters.
•
Applies to all low and high resolution IP cameras, including PTZ cameras and infrared cameras with high
power consumption.
Safety Features:
1. Powers camera only after local unit and remote unit are connected correctly.
2. Auto shutdown for short circuit, open circuit, and overloads.*
3. Auto test and reconnection until the problem is solved.
4. Built-in TVS and GDT against lightning-induced current and transient voltage.
*Safe Power Transmission
Remote modules are tested before the system sends power. When coaxial cable linked between the VDS4000
system has a short circuit or open circuit, the power supply is cut off immediately which shuts down the system
to protect the system and the related camera equipment. The Viewer then activates the auto detection
function, which tests the connection repeatedly. After the connection goes back to normal, the system will reacti-
vate the power supply.
The Local side detects the connection status every 2.5 seconds until the disconnection problem is solved.
The system will shut down if any of the following situations occur:
1. Open circuit—System shuts down after open circuit of the coaxial cable lasts more than 0.5 seconds.
2. Short circuit—System shuts down within 10 micro-seconds after short circuit. When a short circuit
happens, the system detects that the voltage value of the Link IN with DC OUT drops below 70%
and then cuts off power to the control MOS-FET switch. This interval is within 10 micro-seconds.
3. Over loaded—System shuts down when the power is overloadedmore than 10%.
If any of the above circumstances happen, the system will automatically try to reconnect recurringly. Once the
condition is solved, the system will reconnect and supply power again. solved, the system will reconnect and
supply power again.
