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.

Appendix B: Wireless Security

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.
