The Quick Guide of WIFI IP camera’s Wireless Function 1. The configuration of web camera wireless function The default IP address of web camera from factory is: 192.168.1.19. And the default transfer port is: 3000. Both default username and password are: 888888. Open Windows Explorer (IE), input the default IP address, then you can access the web camera. After successful login, click „parameter‟ button in the control panel of video browsing page. Then enter the configuration page of web camera parameters. Choose „wireless network‟ on the left side of screen, see the page as following: Parameter of CDMA: You can choose whether startup CDMA wireless network.. Parameters of Wireless Network: Wireless Status: whether startup Wireless Local Area Network (WLAN) connection of web camera. IP Address: the IP address of web camera in WLAN. Subnet Mask: the subnet mask address of web camera in WLAN. Gateway: the gateway address of WLAN in which web camera locate. DNS: DNS address of WLAN. SSID: ID of wireless network, which is used to divide the id of WLAN. Encryption mode: the mode selection of wireless data transfer encryption. By using WEP encryption mode, you can choose WEP-64 or WEP-128. Cryptographic Key: fill corresponding cryptographic key according to encryption mode selected. If you choose WEP-64 encryption mode, you need to input 5 characters of ASCII, or 10 characters of hexadecimal. If you choose WEP-128 encryption mode, you need to input 13 characters of ASCII, or 26 characters of hexadecimal. After modification, click „confirm‟ button to confirm it. Then enter the page „save or restore configuration‟, click „save configuration‟ to save all configuration, and restart web camera to go into effect. 2. The configuration of wireless router In this text, we use D-Link DI-624+A wireless router to introduce. By using browser to access router and configure, you should input the IP address of router: 192.168.0.254 (the default IP from factory is 192.168.0.1) into Internet Explorer. Username: admin, and keep password empty. After login, select „wireless network‟ in the list on the left side. See the page as following: The setting option of wireless network in router is corresponding with those parameters of wireless network in web camera. So, correspondingly set while configuring. Wireless Network: Wireless Network ID (SSID): wireless network ID is used to divide the ID of WLAN. It shows, SSID of web camera should have the same value as this setting. Signal Channel: to fix working frequency section, selecting area is from 1 to 13. The default is 6. This parameter can be changed from 1 to 13 for reducing wireless disturb among wireless routers when those wireless networks are distributed closely and use the same channel 6. Security Mode: encryption mode selection, this wireless router provides 4 kinds of encryption mode: WEP, 802.1X, WPA-PSK, and WPA to select. Here, we choose WEP mode according to corresponding function of web camera. WEP Cryptography: choose 64bit or 128bit cryptography of WEP mode. Password style: choose the coding style of password characters. You can choose ASCII or HEX (hexadecimal). WEP Password: provide 4 edit boxes for password input. You can choose anyone to use. After setting, click “Execute” button to confirm, wireless router will activate configuration automatically and go into effect. 3. Use web camera Through the configuration of web camera and router, you can use wireless network to connect web camera now. Pull out cyber line from the back panel of web camera, and then input the IP address of web camera into Internet Explorer (IE). After successful login, if there is a monitoring image displayed, it means that connection has succeeded. Glossary of Encryption Mode: SSID (Service Set Identifier) also as ESSID, is used to divide different networks. It has characters no more than 32. Wireless network card can enter different networks by using different SSID. Usually SSID is broadcasted by AP. By using Scan function in XP, you can see SSID in current domain. From security aspect, there could be no broadcasting of SSID. At this time, user has to set SSID manually to enter network. To make a long story short, SSID is the name of a LAN. Only the computers with the same SSID can communicate with each other. Deny SSID Broadcasting In simple words, SSID gives your own wireless network a name. What needs your attention is that the wireless routers or AP from the same producer have the same SSID. If those illegal attackers get advantage of this universal initial character string to connect wireless network, it‟s very easy to establish an illegal connection and threat our network. Thus, author suggests you‟d better change SSID to some special name. Wireless router usually can provide function „agree SSID broadcasting‟. If you don‟t want your wireless network to be searched by others, you‟d better use „deny SSID broadcasting‟. You network still can work, but it can‟t be searched and displayed in others‟ network list. Note: By choosing Deny SSID broadcasting, the performance of wireless network will be affected. But for the exchange of security, author thinks that it is worth doing. What is WEP? WEP, namely Wired Equivalent Privacy, is cryptographic equipment based on 40 bit shared data coded by cryptographic key. For necessary, it‟s unchangeable. So it is likely intruded by attacker. Here we need to warn you that WEP only makes your network more difficult be intruded by hackers. WEP encryption is not included in IEEE 802.11 standard. It means there are several variants of WEP encryption mode. But they are incomplete, such as no encryption for MAC address. What is WPA encryption? WPA encryption, also as Wi-Fi Protected Access, its character of encryption determines it‟s more difficult to be intruded. Therefore, if you have restrict requirement for data security, you must select WPA as encryption mode (Window XP SP2 has already supported WPA encryption). WPA is current best limitless security cryptographic system. It has two ways: Pre-shared key and Radius key. Let explain it simply: 1) Pre-shared key has two cryptographic styles: TKIP or AES. 2) RADIUS key gets advantage of authentication of RADIUS server, and can dynamically choose TKIP, AES, or WEP. Advantages: By using Wired Equivalent Privacy (WEP) to encrypt your wireless network, it can provide lowest level of security, because it‟s very easy to decrypt. If you really want to protect your data, you need to use WPA (Wi-Fi Protected Access), or some safer encryption mode. In order to help you understand, we briefly introduce some available wireless encryption and security technology nowadays: Wired Equivalent Privacy (WEP), it‟s a pseudo standard provided by manufacturers in a hurry. They had to begin their production of wireless equipment before the final confirmation of this standard. Thus, this protocol was found that it exits some bugs. Even a novice attacker can use these bugs of protocol. Wi-Fi Protected Access (WPA), creation of this protocol is to improve and replace the leaky way of WEP encryption. WPA provides a stronger cryptographic way, and solves lots of weakness in WEP. Temporary Key Integrity Protocol is a basic technology. It admits downward compatibility of WEP protocol and current wireless hardware. TKIP and WEP can work together, and compose a longer 128 bit key. And it can change key for every data package. This key is safer than WEP protocol. Extendible Authentication Protocol (EAP). By using EAP, WAP encryption can provide and control more functions about wireless network access. This method not only controls wireless network access by filtering some possibly caught or fake MAC address, it can also control the wireless network access by Public Key Infrastructure (PKI). Although WPA protocol brings big improvement, and it is more and more secure than WEP. But, any encryption is better than nothing. If WEP is the only protecting measure on your wireless equipment, this protecting measure can also prevent some indeliberate hurtful wireless data. And it also prompts most of novice attacker to search others, which have no protection at all.
