1. Overview
EVB-A100(VB) is a product that plays as a bridge between Ethernet LAN or
WLAN and a wireless network. This product is connected with the Tx (Client)
device such as multiple IP cameras and uses Rx (Master) for monitoring from
NVR or PC.
1.1 Functions and Features
(1) Network function
Provides TCP/IP protocol.
Supports video, audio, alarm, voice data, and serial device data service.
If a web browser is installed, IE can be used for access as transmission is made possible
through the TCP/IP network.
(2) General applications
ATM machines, factories and banks that need network (digital) monitoring
Nursing and school services that need remote monitoring
Intelligent gate system or external device monitoring
Bridge and traffic system monitoring, river or wood monitoring to prevent natural
disasters
(3) Settings
EVB-A100 can be set to Rx or Tx. A Rx (Master) is combined with one or multiple Tx’s
(Client) to form a transmitter-receiver system.
Tx transmits data (image and voice data from IP camera) that come into the Ethernet
LAN.
Rx receives wireless data from Tx and sends it to the Ethernet LAN port. NVR or PC can
receive and process the data.
This product includes the latest WiFi technology - 802.11ac 5GHz.

3.2 Installation
3.2.1 Order of Installation
(1) A connection cable is needed.
① Connect the antenna. Connect the cable and power for ¨èLAN.
This product, connected to multiple IP cameras and Tx (client), uses Rx (master) and NVR for
monitoring on the monitor or PC.
Rx and NVR are connected by Ethernet (LAN cable). NVR and the monitor are connected by
the VGA (D-Sub) or HDMI cable and NVR and PC by a LAN cable.
(2) Connect the 12V/1A power cable to Tx and Rx.

(3) On Tx Web UI, the search function is selected, Tx’s Quality LED is turned on.
If Video Bridge’s Tx or Rx setting is completed, Tx and Rx are
automatically connected. If it is not set up, Tx and Rx are not
automatically connected, though the power is only supplied.
Quality LED keeps turned on until Rx’s RSSI reception sensitivity
is -85dbm. When the sensitivity becomes weaker, the LED begins
to flash and then turns off when completely disconnected.
(4) Install it in the way that the ventilated disk hole does not face towards the floor.
(5) Use the LAN cable to connect Tx with an IP camera.
(6) Use the LAN cable to connect Rx with NVR.
(7) To change Rx settings, connect Rx with the PC and go the setting page on the Web to

The followings are the measures to be taken when a problem occurs while using Video
Bridge. If the problem is not cured, please contact the customer center.
If the device needs to reset the settings, press the Reset button on the
side of the product for more than 10 seconds.
Faults Symptoms Measures
The product does
not operate.
Power LED is turned off.
Power may be unplugged.
Check if the power cord is properly
connected.
Tx’s Mode LED is turned on,
or Power LED is turned off.
Mode LED may be turn off or
on which is selected, Tx or Rx mode.
Go to [Config]>[Wireless] of Web UI
and check if mode is selected Tx or Rx.
Tx is not connected
with Rx.
Link LED flashes or is turned
off.
The connection between Tx and Rx lost
wireless connection or unstable.
Check the power and the settings of Tx
and Rx.
Video is lagging or
blank
Quality LED flashes or is
turned off.
Check if the four antenna are all
correctly connected.
Check it from the nearest location
first.

9. Terminology
Rx(
Master
)
Rx is a receiver which connects wired and wireless connectivity.
Tx (Client)
A transmitter is connected to a receiver.
SCS
Smart Channel Selection
VSP
Video Stream Protection
RSSI
Received Signal Strength Indication
Wi-Fi
A mark for WECA to check linking between wireless products. The name is originated
from "Wireless Fidelity". WECA carries out an elaborate test and grants a Wi-Fi logo to a
product that satisfies the linking standards.
Wireless Bridge
Tx (Client) or Rx ( Master) that uses a wireless network to connect between two different
wired networks.
Association
Has a table that controls the packet route between Rx and Tx
Maintains Rx and Tx.
SSID
Service Set Identifier
SSID is a unique identifier of 32 bytes length added to the header of a packet
transmitted through a WLAN. It is used like a password when Tx connects to BSS (basic
service set). Rx or Tx must the same SSID. A Tx that does not know the unique of a
certain BSS cannot access the BSS.
WEP
WEP (Wired Equivalent Privacy): An encryption standards prepared by IEEE 802.11 for
WLAN security. There are various types of application developed to use encryption keys
to strength security.
B
andwidth
Refers to the difference between the highest and lowest frequencies of a signal usable in
a network. It means, commonly, the highest transmission speed or a capacity to transmit
information and uses ‘bps’ its unit.
DHCP
DHCP allows the network administrator to manage and allocate IP addresses and to send
new IP addresses when the computer connects to a different location of the network.
Static IP
Can use fixed IP addresses. There is no need for the administrator to allocate IP
addresses.
802.11ac
802.11ac operates at 5G Hz’s V10.1 frequency bandwidth.
PHY
The lowest sub layer of the physical layer and a block for connection with the
outside. It changes a protocol layer into a physical layer.
WDS
Wireless Distribution System
WDS forms a wireless network between Rx’s to provide the larger support range of
wireless network than when one Rx is used.
BSS
Base Service Set
Refer to a minimal size of WLAN formed based on a Rx if a wire network consists of
multiple wireless Rx’s in the infrastructure mode.

AES
Advanced Encryption Standard
CCMP
Counter Mode Encryption With CBC-MAC Protocol
EAP
Extensible Authentication Protocol
ESS

Refers to a WLAN that consists of multiple Rxs.

PEAP

TLS
Transport Layer Protocol
WPA
WiFi Protected Access
WIFI security Protagoras WEP -> WPA - WPA2
Wi-Fi Protected Access (WPA, WPA2 ) is an authentication program carried out under
the monitoring of Wi-Fi Alliance. It is a security protocol that indicates that the network
equipment satisfies the security protocol established by Wi-Fi Alliance. WPA indicates
that the existing LAN card operation complies with the expansion protocol standards
completely and WPA2 mark indicates that the relevant device does the same.
WPS
WiFi Protected Setup
Press the WPS buttons of the wireless Rx and wireless device (during the 120 seconds of
waiting time) to establish connection without entering password: there are PBC, PIN,
and NFC type.
PMF
Protected Management Frames
Protects the frame.
RADIUS
Remote Authentication Dial-in User Service
NSS
Number of Spatial Streams
DTIM
Delivery traffic indication message
Short GI
Short Guard Interval
The guard interval is a waiting time between sending data continuously in a wireless
network to reduce the impact of data. For 802.11 a/g, it is 800 nsec, but for 802.11n, it is
set to 400n sec so that the sub carrier can be used to compensate for the reduced guard
interval to make the total throughout to reach 72Mbps. Reducing the guard is provided
as a optional when a WLAN is established as interval needs agreement between the
transmission and reception ends.
OFDM
Orthogonal Frequency Division Multiplexing
MIMO
Multi Input Multi Output
MIMO is a multi I/O technology. The wireless quality depends on how far the signal is
and which route the signal is received. MIMO uses multiple antennas to receive signals
coming in along multiple paths (multipath) and operate data and recover them to
original signals. 802.11g/b/g uses a single antenna or SISO (Single Input Output).
Passphrase
It is used instead of password to mean that the password should long enough.
