The Wireless Channel sets the radio frequency used for communication.
•Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent
Access Points use different Channels to reduce interference.
• In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest
signal is used. (This can only happen within an ESS.)
• If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
Note:This equipment marketed in USA is restricted by firmware to only operate on 2.4G channel 1-11

Chapter 1
Introduction
This Chapter provides details of the Network Camera's features, components
and capabilities.
Overview
The Network Camera has an Integrated Microcomputer and a high quality CMOS digitalImage-Sensor, enabling it to display high quality live streaming video over your wired LAN,
the Internet, and for the Network Camera, an 802.11g Wireless LAN.
Using enhanced MPEG-4 technologies, the Network Camera is able to stream high quality
video and audio directly to your PC. The high compression capabilities of MPEG-4 reduce
network bandwidth requirements to amazingly low levels.
A convenient and user-friendly Wind ows program is provided for both viewing and r ecording
video. If necessary, you can even view video using your Web Browser, on a variety of software
platforms.

Figure 1: Network Camera
Features
• Standalone Design. The Network Camera is a standalone system with built-in CPU and
Video encoder. It requires only a power source and a connection to your LAN or Wireless
LAN.
Stream Live Video to Multiple Users. The MPEG4 encoder and HTTP server built
•
into the camera generate a ready-to-view video stream. Just connect to the camera using
your Web browser or the provided Windows utility to view live video.
1
•
Suitable for Home, Business or Public Facilities. Whether for Home, Business or
Public Facility surveillance, or just for entertainment and fun, the Network Camera has the
features you need.
Multi-Protocol Support. Supporting TCP/IP networking, SMTP (E-mail), HTTP and
•
other Internet related protocols, the Network Camera can be easily integrated into your
existing network.
Easy Configuration. A Windows-based Wizard is provided for initial setup.
•
Subsequent administration and management can be performed using a standard web
browser. The administrator can configure and manage the Network Camera via the LAN
or Internet.
• Viewing/Recording Utility. A user-friendly Windows utility is provided for viewing
live video. For periods when you are absent, or for scheduled recording, this application
also allows you to record video to an ASF file on your PC. The recorded files are in a
standard Windows Media format, and thus usable by a wide variety of programs if
required.
• Motion Detection. This feature can detect motion in the field of view. The Network
Camera will compare consecutive frames to detect changes caused by the movement of
large objects. This function only works indoors due to the sensitivity of the CMOS sensor.
When motion is detection, an E-mail alert can be sent, or some other action may be
triggered.
Flexible Scheduling. You can limit access to the video stream to specified times using
•
a flexible scheduling system. The Motion Detection feature can also have its own
schedule, so it is active only when required.
Audio Support. You can listen as well as lo ok! Audio is encoded with the video if
•
desired. You can use either the built-in microphone or an external microphone.
PoE Support. (NC402A* only) You can use PoE (Power over Ethernet) to provide
•
power to the Network Camera, so only a single cable connection is required.
Internet Features
• User-definable HTTP port number. This allows Internet Gateways to use "port
mapping" so the Network Camera and a Web Server can share the same Internet IP
address.
•
DDNS Support. In order to view video over the Internet, users must know the Internet
IP address of the gateway used by the Network Camera. But if the Gateway has a dynamic
IP address, DDNS (Dynamic DNS) is required. Since many existing Gateways do not
support DDNS, this function is incorporated into the Network Camera.
NTP (Network-Time-Protocol) Support. NTP allows the Network Camera to
•
calibrate its internal clock from an Internet Time-Server. This ensures that the time stamp
on Video from the Network Camera will be correct.
Security Features
• User Authentication. If desired, access to live video can be restricted to known users.
Users will have to enter their username and password before being able to view the video
stream. Up to 20 users can be entered.
Password-Protected Configuration. Configuration data can be password protected, so
•
that it only be changed by the Network Camera Administrator.
2
Wireless Features (NC802APT* and NC802A* only)
• Standards Compliant. The Network Camera complies with the IEEE802.11g (DSSS)
specifications for Wireless LANs.
Supports both 802.11b and 802.11g Standards. The Network Camera supports both
•
802.11b and 802.11g standards.
Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are supported.
•
Wired and Wireless Network Support. The Network Camera supports either wired and
•
wireless transmission.
WEP Support. Full WEP support (64/128 Bit) on the Wireless interface is provided.
•
WPA-Personal Support. The WPA-Personal (WPA1) standard is also supported,
•
allowing advanced encryption of wireless data.

Controlling User Access to the Video Stream
By default, anyone can connect to the Network Camera and view live Video at any time.
If desired, you can limit access to scheduled times, and also restrict access to known users.
To Control User Access to Live Video:
1. Connect to the Web-based interface of the Network Camera. (See Chapter 5 - Web- based
Management for details.)
2. Select Administration, then Video Access.
3. Set the desired options for Access.
Access
If the Video Access is enabled, users cannot connect using either their Web Browser or the
Windows utility. However, viewing video is still possible by logging in as the Administrator.

See Chapter 5 - Web-based Management for further details about using the Video Access and
User Database screens.
