What Are The Risks?
Wireless-B Internet Video Camera
The solution, then, is to segment your network up into multiple groups. If your network had 80 users and you
used four WEP keys, a hacker would have access to only ¼ of your wireless network resources. In this way,
multiple keys reduce your liability.
Finally, be sure to change your WEP key regularly, once a week or once a day. Using a “dynamic” WEP key, rather
than one that is static, makes it even harder for a hacker to break into your network and steal your resources.
WEP Encryption
There are two ways to enable WEP encryption for the Camera. The first way is through the Setup Wizard, and the
second way is through the Web-based Utility. To use the Setup Wizard, refer to “Chapter 5: Setting up and
Mounting the Wireless-B Internet Video Camera.” To use the Web-based Utility, follow these instructions:
1.
Click the
Setup
tab of the Web-based Utility.
2.
On the
Basic
screen, click
Enable
next to WEP.
3.
Click the
Edit WEP Settings
button.
4.
The
WEP Key Settings
screen will appear. See Figure B-2.
5.
Select the Default Transmit Key used by your wireless network.
6.
From the
WEP Encryption
drop-down menu, select
64 Bit Keys (10 Hex chars)
or
128 Bit Keys (26 Hex
chars)
, depending on the level of encryption your wireless network uses.
7.
Enter a Passphrase in the
Passphrase
field, and click the
Generate
button to create WEP key(s). The
Passphrase is case-sensitive and should have 16 alphanumeric characters or fewer.
If you do not want to use a Passphrase, then enter the WEP keys manually in the
Key 1
to
Key 4
fields. Each
WEP key must consist of valid hexadecimal characters, the letters “A” through “F” and numbers “0” through
“9”. For 64-bit WEP encryption, the key must consist of exactly 10 hexadecimal characters. For 128-bit WEP
encryption, the key must consist of exactly 26 hexadecimal characters.
8.
From the
Authentication
drop-down menu, select your wireless network’s authentication type,
Open System
or
Shared Key
. The default is set to Open System, for which the sender and recipient do NOT use a WEP key
for authentication. You can also choose Shared Key, when the sender and recipient use a WEP key for
authentication. This setting should match the one on your network’s access point or wireless router.
9.
Click the
Apply
button to save your changes.
Important:
Always remember that each
device in your wireless network MUST use
the same WEP encryption method and
encryption key or your wireless network will
not function properly.
