Encryption WEP Key: (for Wireless Internet Camera only)
Wireless network communications are easily intercepted. WEP (Wired
Equivalent Privacy) is an encryption method specified by the IEEE 802.11b
standard to make any intercepted communications extremely difficult to interpret
by unauthorized parties.
To enable WEP Encryption, first decide which WEP key format will be applied.
Click on ASCII or HEX check box to select input format as ASCII format or HEX
format, and then input the WEP key. To Confirm the WEP key you must enter
the data once again in the Confirm WEP Key field.
ASCII input format: (for Wireless Internet Camera only)
ASCII format causes each character you type to be interpreted as an eight-bit
value. All unaccented upper- and lower-case Western European characters
that can be input through your keyboard's typing zone are valid. To setup 64-bit
WEP key, input 5 ASCII characters, for example, '12345'. To setup 128-bit WEP
key, input 13 ASCII characters, for example, '1234567890123'. These character
counts result in bit counts of 40 and 104, respectively; the Internet Camera will
automatically pad your input to a bit count of 64 or 128.
HEX input format:
Hex format causes each pair of characters you type to be interpreted as an
eight-bit value in hexadecimal (base 16) notation. Only the digits 0 through 9
and the letters A through F (in upper or lower case) are valid. To setup 64-bit
WEP key, input 10 HEX format, for example, '3132333435', this is the same
with ASCII input '12345'. To setup 128-bit WEP key, input 26 HEX format, for
example, '31323334353637383930313233', this is the same with ASCII input
'1234567890123'. These character counts result in bit counts of 40 and 104,
respectively; the Internet Camera will automatically pad your input to a bit count
of 64 or 128.
On the Confirm WEP Key field, input the same characters as the Encryption
Code field.
Make sure the Encryption Code is the same with the access point's encryption
code that the Internet Camera is to be connected under Infrastructure mode.
Your PC/Notebook's encryption code also needs to be setup the same with the
Internet Camera's encryption code under either Infrastructure mode or Ad-hoc
mode.
