must be manually set to the same channel for each wireless adapter. The default
channel setting depends on the installed region.
“TX rate” This field is for selecting the maximum transmission rate on the network.
The default setting is “auto”, that is the Network Camera will try to connect to the other
wireless device with highest transmitting rate.
“Preamble”, either “Long preamble” or “Short preamble” defines the length of
the CRC block (Cyclic Redundancy Check is a common technique for detecting data
transmission errors) for communication between the Access Point and the roaming
wireless device. Long Preamble is the default setting. Note: High network traffic areas
should use the shorter preamble type.
“Data encryption” Checking the box to enable the data encryption. By default it is
disabled.
“Auth. Mode” Choosing one of the following modes, (Open is the default setting)
z
“Auto” – The selection will apply Shared mode authentication method. This is the
most strict mode.
z “Shared” – allows communication only with other devices with identical WEP
settings.
z “Open” – communicates the key across the network.
“Key length” The administrator can select the key length among 64 or 128 bits.
64bits is the default setting.
“Key format” Hexadecimal or ASCII. “HEX” is the default setting.
z
“HEX” digits consist of the numbers 0~9 and the letters A-F.
z “ASCII” is a code for representing English letters as numbers from 0-127 except
“, <, > and space characters that are reserved.
“Network Key” Entering a key in either hexadecimal or ASCII format. When selecting
different key length, acceptable input length is listed as following:
64 bits key length: 10 Hex digits or 5 characters.
128 bites key length: 26 Hex digits or 13 characters.
Note: When 22(“), 3C(<) or 3E(>) are input in network key, the key format can’t be
changed to ASCII format.
