Introduction of
2Y-LINK
Technology
1.1
2Y-LINK Technology
is a patented new concept, which has been successfully applied in
the CCTV surveillance system with multi-functions, such as power, video, two-way audio,
sensors, emergency signals and control data transmission,
using a single pair of ordinary
Bell Cable or an unshielded twisted pair of Cat.5 Cables between the Mixer at camera side
to Signal Processor at DVR side.
1.2 It consists of a
Mixer
installed close to the camera and a
Signal Processor
installed close to the DVR/Monitor. The transmission of power, video, two-way audio,
sensors, emergency signals and control data between
Mixer
and
Signal Processor
is
provided through a single pair of Bell Wires (AWG24-AWG18) or an unshielded twisted pair
of Cat.5 Cable, for distance of up to 2,000 meter (6,600 ft.), depending on the choice of
Signal Processor model together with the associated Mixer for the actual application in the
CCTV surveillance system.
1.3 The
Signal Processor
supplies power and transmits control data and audio signals
through the single pair of wires to the camera (applicable device) and at the same time
receives, through the same single pair of wires, video and other signals continuously from the
camera (applicable device) and channels them to the DVR/Monitor/applicable equipment.
1.4 The
Mixer
receives power and multifunctional data from the
Signal Processor
via the
single pair of wires, regulates/stabilizes them and distributes them to the camera/applicable
device and simultaneously transmits video and other signals back to the
Signal Processor
.
The following diagram shows examples of some typical applications of 2Y-LINK
Technology in CCTV surveillance systems using just one pair of cable.
