Chapter I General Description
1.1 Description
The V2401 series video distribution amplifiers provide 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 V2401 series are designed as easy-to-use solution for these
conditions. They amplify a single video signal, and distribute it to a
total of 16 outputs. 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 V2401 series are plug-and-play devices that require no manual
adjustment. Two LEDs are provided in the front panel to indicate
system power status and video signal presence.
Rack or desktop mount options are available for different
configurations.

2.3 Hardware Connections
2.3.1 Video Input Connections
The V2401 provides one BNC connector, labeled as "VIDEO
INPUT", for connecting one composite video input. Video is input
into the V2401 by connecting an external video source (e.g., a
camera) to a BNC connector.
Please refer to the following table to select appropriate coaxial
video cables:
Table 2-1. Coaxial Cable & Maximum Operating Distance
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 V2401 amplifies a single video input signal and distributes it to
a total of 16 outputs. 16 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:
zProperly install the monitor according to relevant manuals.
zConnect the necessary coaxial video cables to the desired BNC
output port located on the rear panel of the V2401.
zSet 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).
For typical video connections, please refer to the following
diagram.
2.3.3 Power Connection
The V2401 is designed for a 120VAC/60Hz power source, and
V2401X for 230VAC/50Hz. All Infinova units with a model
number suffixed with "X" are designed for a 230VAC/50Hz power
source.
Warning:
When powering the V2401, 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.
