3.WPA-PSK: Use WPA (Wi-Fi Protected Access) pre-shared key.

More secure than WEP, the Wi-Fi Alliance developed WPA (Wi-Fi Protected Access) in 2003 to address WEP’s weaknesses. Improvements included TKIP, which changes the encryption key for each data transmission.

■Algorithm: Choose one of the following algorithms for WPA-PSK and WPA2-PSK modes.

TKIP (Temporal Key Integrity Protocol): A security protocol used in IEEE 802.11 wireless networks. TKIP is a “wrapper” that goes around the existing WEP encryption. TKIP is comprised of the same encryption engine and RC4 algorithm defined for WEP; however, the key used for encryption in TKIP is 128 bits long. This solves the first problem of WEP: a short key length. (From Wikipedia)

AES (Advanced Encryption Standard): In cryptography, the Advanced Encryption Standard (AES), also known as Rijndael, is a block cipher adopted as an encryption standard by the U.S. government.

As of 2006, AES is one of the most popular algorithms used in symmetric key cryptography. (From Wikipedia)

■Pre-shared Key: Enter a key in ASCII format. The length of the key can be between 8 to 63 characters.

4.WPA2-PSK: Use WPA2 pre-shared key.

This advanced protocol, certified through Wi-Fi Alliance’s WPA2 program, implements the mandatory elements of 802.11i. In particular, it introduces a new AES-based algorithm, CCMP, that is considered fully secure. From March 13, 2006, WPA2 certification is mandatory for all new devices wishing to be certified by the Wi-Fi Alliance as “Wi-Fi CERTIFIED.” (From Wikipedia)

NOTE:

►After wireless configurations are completed, click Save and the camera will reboot. Wait for the live image ito be reloaded to your browser. For VIVOTEK 81xx-series cameras, you have to unplug the power and Ethernet cables from the camera; then re-plug the power cable to the camera. The camera will then switch to wireless mode.

►Some invalid settings may cause the system to fail to respond. Change the configuration settings only if necessary and consult with your network supervisor or experienced users for correct settings. Once the system has lost contact, please refer to Maintenance on page 105 for reset and restore procedures.
