I. Introduction
•What is Webthru SWC 306?
The Webthru SWC 306 is a network CCTV camera server solution with an integrated Internet server, image
compression device, flash memory, and many other features. No other hardware is necessary for use. The
Webthru SWC 306 relays video source from a CCTV camera to network and provides real time images over
networks and the Internet. Simply provide power and connect LAN cable and video cable to the Webthru
SWC 306. Webthru SWC 306 utilizes Wavelet image compression and Linux operating system. Wavelet and
Linux enable Webthru SWC 306 to transfer high quality images faster and with a greater degree of reliability
than standard JPEG systems.
•Features and Benefits
Ease of Use – Webthru SWC 306 requires Microsoft Internet Explorer 5.0 (or higher) for use. Windows 2000
is recommended for best results. Connect Webthru SWC 306 to the Internet and it is ready for use.
Compatible with most Systems and Protocols – Webthru SWC 306 supports TCP/IP networking, SMTP,
HTTP and other Internet-related protocols. In addition, the Webthru SWC 306 can be used in mixed
operating system environments, such as Windows, UNIX, Macintosh and OS/2. Webthru SWC 306 also
integrates easily into other Internet/Intranet applications and CGI scripts.
Simple Administration - Webthru SWC 306 can be configured and managed directly from its own web page.
Moreover, as new upgrades become available, it is easy to upgrade Webthru SWC 306 remotely over the
network.
Wavelet Image Format - Unlike many other products that need to fracture image files prior to broadcast, the
Webthru SWC 306 delivers complete, highly compressed pictures in Wavelet format. Wavelet has image
compression rates 30-300% higher than standard JPEG. By utilizing Wavelet, image file sizes are much
smaller than conventional camera servers and Wavelet's image quality is superior to other camera servers as
well. Wavelet can transmit up to 123 frames per second.
External Device Connection - External devices such as IR-sensors, switches, alarm relays and external
video input can be connected to Webthru SWC 306 via six auxiliary Input ports.
User’s Programmable Space – Webthru SWC 306 contains 4.5MB of configurable Flash Memory for user-
programmable and user-configurable space. Because Webthru SWC 306 also acts as a server, this space can
be used to create a personal web page.
Embedded Linux Operating System – Webthru SWC 306 uses an embedded Linux operating system
within its 32bit RISC CPU. Linux is based on UNIX and is one of the most stable operating systems
available. There is very little chance of the operating system crashing.

2) Verifying Installation
After successfully completing the above procedures, the following message (or similar) will appear on the
screen.
Request timed out
:
Request timed out
Reply from 200.243.232.178: bytes=32 time=2ms TTL=255
Reply from 200.243.232.178: bytes=32 time=2ms TTL=255
Ping statistics for 200.243.232.178:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milliseconds:
Minimum = 1ms, Maximum = 2ms, Average = 1ms
If the above “ping” reply does not appear, press 'F3' and 'Enter' keys. Normally “Request timed out”
messages appear 7 times before replying properly.
Once the above “ping” reply appears press <Ctrl>+<C> keys to make it stop.
When the “ping” replies stops, data loss may range from 0% to 99%. This is normal. If the statistic shows
‘100% loss’, check the following criterions: (a) network line and connection status are stable; (b) IP address
assigned to Webthru is available; (c) PC and Webthru have the same local network IP address. Same local IP
address of C grade network means that first 3 sets of numbers are the same but the fourth set is different. For
example 192.168.1.2 and 192.168.1.3 are in the same local network. (If there is a ‘Network Mask’ on the
network, this can be an exception. For detailed information on IP, refer to appendix 3)

user may access real time image viewer page.
2. Configuring Administrator’s Condition at Homepage
1) System Configuration
This page is to set name, date &
time, location, and description
of one’s Webthru. Model, serial
number, and software version
appear automatically.
(1) Webthru Name
The name is to be used to
register the Webthru on a
certain server, if dynamic IP
address is used. Therefore it is
very important to set a proper
name for user to find the
Webthru in the dynamic IP
registration list. (For detailed information, refer to ‘Dynamic IP Registration Service for ISDN, xDSL User’)
(2) Model
By clicking ‘Detailed H/W Information’, administrator may view the detailed hardware information such as
maximum numbers of channel, serial port, digital input, digital output, etc. The model name is marked
automatically.
(3) Installation Location & Additional Description
The information is to show in a dynamic IP registration list.
(4) Date & Time
There are three date & time menus. In “Webthru Current Date & Time” panel, the date and time that is set in
the Webthru appears. In “System (PC) Current Date & Time” panel, the same date and time that is set in
user’s PC appears. To synchronize the Webthru and PC date and time, an administrator can click the “Time

Webthru SWC 306 User’s Guide
Synchronization” button. The “Manual Date & Time” panel allows the user to set date and time.
(5) Administrator’s E-mail Address
In this panel, administrator records one’s e-mail address. If administrator put a ‘contact’ menu of e-mail
communication on real time image viewer page, the linked e-mail address to the ‘contact’ menu is to be
synchronized with this. So administrator can keep up e-mail address easily.
(6) Initialize Flash Info
This will initialize almost all the information saved on Flash Memory. However Date & Time, Model, Serial
Number, and IP configuration of “System Configuration”, and Video Signal Type of “Video Configuration”
menus will not be changed.

If Webthru has any problems, administrator can reboot it without adjusting power supply. This button works
as on/off switch.

passwords of an administrator and 5
users.

There are one administrator’s
account and 5 users’ accounts.

you should change administrator’s ID and password as unique ones.
(3) Access Rights
Administrator may give or take users’ right of PTZ control and video control. With default setting,
administrator has both right of PTZ control and video control and normal user doesn’t have any right.
•Video control: This is to control pop-up menus such as image quality level and QBOX settings.

every host on a LAN may share limited official IP address for Internet access. In other words, every host on a
LAN may lease official IP address from DHCP server temporarily.
