Compact Wireless-G Internet Video Camera
10.I already set up my SoloLink DDNS account, but I can’t access the Camera from a remote location.
Follow these instructions:
When you enter the Camera’s domain name, make sure it is in this format:
http://
<Device Name>.<Location ID>
.ourlinksys.com
The <Device Name> is the name you gave the Camera when you ran the Setup Wizard. The <Location ID>
is the name you selected when you set up your SoloLink DDNS account.
If the Camera is set to DHCP, make sure your local network is working properly and your router has an
active Internet connection.
If the Camera uses a static IP address, insert the Setup CD-ROM into your network PC’s CD-ROM drive.
Click the
Setup
button and follow the on-screen instructions. When you see the
IP Settings
screen, make
sure the Camera’s Default Gateway and Primary DNS addresses are correct. For more information, refer to
“Chapter 5: Setting up and Mounting the Compact Wireless-G Internet Video Camera.”
Frequently Asked Questions
Can I view video using a Macintosh or Netscape Navigator?
The Camera is designed for computers running a Windows operating system and Internet Explorer 5.5 or higher.
You cannot view video on a Macintosh. If you only have Netscape, you can view video using the Multi-Camera
Viewer & Recorder Utility. See “Chapter 6: Installing and Using the Compact Wireless-G Internet Video Camera
Multi-Camera Viewer & Recorder Utility.”
Can I directly connect the Camera to wired and wireless networks at the same time?
No. Before powering on the Camera, you should decide if you want to connect the Camera to a wireless network
via an access point or to a wired network. If your wireless and wired networks are bridged, then you can access
the Camera from any networked computer, but the Camera must be directly connected to only one of the
networks.
To connect the Camera to a wireless network, power on the Camera with no network cable attached. The Camera
will be ready for use when the LED is lit continuously.
To connect the Camera to a wired network, connect the network cable to the Camera, and then power it on. The
Camera will be ready for use when the LED is lit continuously.
Can I install the Camera outdoors?
No, the Camera was not designed for outdoors usage.
I’ve recorded video for a few hours. Why do I see multiple files saved on my computer?
The recording function saves video in chunks; each chunk is a maximum of one hour in duration. For example, if
you have recorded five continuous hours, then you will see five files saved on your computer. This keeps files
from getting too large.

Yes. Access the Camera’s Web-based Utility, and click the
Setup
tab. After you log in, click the
Users
tab. You will
be able to restrict access to users you have entered in the database. See “Chapter 8: Using the Compact
Wireless-G Internet Video Camera Web-based Utility.”
Can I add a time stamp to the video?
Yes. Access the Camera’s Web-based Utility, and click the
Setup
tab. After you log in, click the
Image
tab. You
will be able to add a time stamp as well as descriptive text to the video. See “Chapter 8: Using the Compact
Wireless-G Internet Video Camera Web-based Utility.”
How many users can view the Camera’s video at the same time?
Users at four different PCs can simultaneously view the Camera’s video.
What is the IEEE 802.11b standard?
It is one of the IEEE standards for wireless networks. The 802.11b standard allows wireless networking hardware
from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard.
The 802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.
What is the IEEE 802.11g standard?
It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware
from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard.
The 802.11g standard states a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz.
What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11b functions:
CSMA/CA plus Acknowledge protocol
Multi-Channel Roaming
Automatic Rate Selection
RTS/CTS feature
Fragmentation
Power Management

What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to
communicate directly with each other. The ad-hoc wireless network will not communicate with any wired
network.
What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a
wired network through a wireless access point or router.

Security Precautions
Compact Wireless-G Internet Video Camera
Appendix B: Wireless Security
Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of
Linksys products provide several network security features, but they require specific action on your part for
implementation. So, keep the following in mind whenever you are setting up or using your wireless network.
Security Precautions
The following is a complete list of security precautions to take (at least steps 1 through 5 should be followed):
1.
Change the default SSID.
2.
Disable SSID Broadcast.
3.
Change the default password for the Administrator account.
4.
Enable MAC Address Filtering.
5.
Change the SSID periodically.
6.
Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce
your network performance.
7.
Change the encryption keys periodically.
Security Threats Facing Wireless Networks
Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking
products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the
network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:
Change the administrator’s password regularly.
With every wireless networking device you use, keep in mind
that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only
person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can
change those settings. So, make it harder for a hacker to get that information. Change the administrator’s
password regularly.
NOTE:
Some of these security features are
available only through the network router or
access point. Refer to the router or access
point’s documentation for more information.

SSID.
There are several things to keep in mind about the SSID:
1.
Disable Broadcast
2.
Make it unique
3.
Change it often
Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be
more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast
the SSID.
Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.)
Hackers know these defaults and can check these against your network. Change your SSID to something unique
and not something related to your company or the networking products you use.
Change your SSID regularly so that any hackers who have gained access to your wireless network will have to
start from the beginning in trying to break in.
MAC Addresses.
Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only
those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with
a random MAC Address.
WEP Encryption.
Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security
concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job
more difficult.
There are several ways that WEP can be maximized:
1.
Use the highest level of encryption possible
2.
Use “Shared Key” authentication
3.
Change your WEP key regularly
WPA
. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. For encryption,
WPA Personal automatically uses Temporal Key Integrity Protocol (TKIP), which incorporates Message Integrity
Code (MIC) to provide protection against hackers. For the
Passphrase
field, enter the key shared by the devices
on your wireless network. (This key should have 8-63 characters and can also be called a WPA shared key or pre-
shared key.)
IMPORTANT:
Always remember that each
device in your wireless network MUST use
the same encryption method and encryption
key or your wireless network will not function
properly.
