Chapter I General Description
1.1 Description
The V2403 series Video Distribution Amplifier provides a
cost-effective means of maintaining CCTV video quality for
long-distance transmission and for video signal distribution.
In most CCTV surveillance/security applications, live video images
from a site camera may require to be transmitted over a long
distance or be viewed at different control sites. In each case, the
video transmission may be hampered by signal attenuation and
undesirable noises.
The V2403 series Video Distribution Amplifier is designed as an
easy-to-use solution for these conditions. It amplifies a set of 4
video signals, and distributes them into 8 sets of video outputs (4 for
each), or it amplifies a set of 8 video signals, and distributes them
into 4 sets of video outputs (8 for each), or it amplifies a set of 16
video signals, and distributes them into 2 sets of video outputs (16
for each),. Each video output has the same quality as the original
input signal, ensuring non-degrading transmission over a long
distance or to different sites.
The distribution amplifier is compatible with standard B&W and
color video systems, and features a wide frequency response.
The V2403 series Video Distribution Amplifier is a plug-and-play
device that requires no manual adjustment.
Rack or desktop mount options are available for different
configurations.

2.3 Hardware Connections
2.3.1 Video Input Connections
The V2403-4 provides a group of 4 BNC connectors, labeled as
"VIDEO INPUT”. The V2403-8 provides a group of 8 BNC
connectors, labeled as "VIDEO INPUT". The V2403-16 provides a
group of 16 BNC connectors, labeled as "VIDEO INPUT". Each

2
can be used to connect one composite video input. Video is input
into the V2403 by connecting an external video source (e.g., a
camera) to a BNC connector.
V2403-4 distributes each video input into 8 video outputs through
the four video output connectors labeled the same number as the
input connectors.
V2403-8 distributes each video input into 4 video outputs through
the four video output connectors labeled the same number as the
input connectors.
V2403-16 distributes each video input into two video outputs
through the two video output connectors labeled the same number
as the input connectors.
Please refer to the following table to select appropriate coaxial
video cables:

Coaxial Cable Type Max. Transmission Distance
RG59/U 750 ft (229 m)
RG6/U 1000 ft (305 m)
RG11/U 1500 ft (475m)
2.3.2 Video Output Connections
The V2403-4 amplifies a set of 4 video input signals and distributes
them to a total of 32 outputs.The V2403-8 amplifies a set of 8 video
input signals and distributes them to a total of 32 outputs. The
V2403-16 amplifies a set of 16 video input signals and distributes
them to a total of 32 outputs. 32 BNC connectors, labeled as
"VIDEO OUTPUT", are provided on the rear panel for connecting
video outputs (e.g., monitors).
To connect a monitor to its associated video output terminal:
1. Properly install the monitor according to relevant manuals.
2. Connect the necessary coaxial video cables to the desired BNC
output port located on the rear panel of the V2403.
3. Set the monitor’s termination to 75 ohm.
Note: If the video is being looped through a monitor, the
termination must be set at High Resistance (HiZ).
2.3.3 Power Connection
The V2403 series Video Distribution Amplifiers are designed for a
100~240V AC power source.
Warning: Do not power on the device when connecting wires.
Note: When powering the V2403, check that the power source
specifications correspond to those required. The use of improper
components or equipment will seriously compromise the safety of
the personnel and the installation.

Appendix III Cable Diameter Calculation and Lightning & Surge Protection
Relation between 24VAC Cable Diameter and Transmission Distance
In general, the maximum allowable voltage loss rate is 10% for AC-powered devices. The table below shows the relationship between
transmission power and maximum transmission distance under a certain specified cable diameter, on condition that the 24VAC voltage loss
rate is below 10%. According to the table, if a device rated at 50W is installed 17-meter away from the transformer, the minimum cable
diameter shall be 0.8000mm. A lower diameter value tends to cause voltage loss and even system instability.

Lightning & Surge Protection
The product adopts multi-level anti-lightning and anti-surge technology integrated with gas discharge tube, power resistor and TVS tube. The
powerful lightning and surge protection barrier effectively avoids product damage caused by various pulse signals with power below 4kV,
including instantaneous lightning, surge and static. However, for complicated outdoor environment, refer to instruction below for lightning
and surge protection:
The product features with dedicated earth wire, which must be firmly grounded. As for surveillance sites beyond the effective protection
scope, it’s necessary to erect independent lightening rods to protect the security devices. It’s recommended to separate the lightning rod from
the mounting pole, placing the rod on an independent pole, as shown in the figure below. If the product has to be installed on the same pole or
pedestal for lightning rod, there should be strict insulation between the video cable BNC terminal, power cable, control cable and the standing
pole of the lightning rod.
For suburb and rural areas, it’s recommended to adopt direct burial for the transmission cables. Overhead wiring is prohibited, because it’s
more likely to encounter lightning strike. Use shielded cables or thread the cables through metal tubes for burial, thus to ensure the electric
connection to the metal tube. In case it’s difficult to thread the cable through the tube all the way, it’s acceptable to use tube-threaded cables
only at both ends of the transmission line, yet the length in burial should be no less than 15 meters. The cable sheath and the tube should be
connected to the lightning -proof grounding device.
Additional high-power lightning-proof equipment and lightning rods should be installed for strong thunderstorm or high induced voltage
areas (such as high-voltage substation).
The lightning protection and grounding for outdoor devices and wires should be designed in line with the actual protection requirement,
national standards and industrial standards.
The system should perform equipotential grounding by streaming, shielding, clamping and earthing. The grounding device must meet
anti-interference and electric safety requirements. There should be no short-circuiting or hybrid junction between the device and the strong
grid. Make sure there’s a reliable grounding system, with grounding resistance below 4Ω(below 10Ωfor high soil resistivity regions). The
cross-sectional area of the earthing conductor should be no less than 25mm².
