MPEG4 NETWORK IP CAMERA User’s Guide 6.3 Network Configuration This screen defines the network type and addresses of the Mpeg4 Network IP Camera. Here you can configure the Camera’s IP address, the DNS server address, and the Server IP address. Each configuration takes just a few seconds for booting after pressing “Submit”. 1. Set IP Address, Subnet mask, gateway address. To set the IP address, Subnet mask, and gateway address manually, you may select “manually” in combo box. In case of selecting “manually”, you can configure them with the IP installer as well as this page. (If you have any trouble in configuring network system information, please ask your network administrator.) To set DHCP, you may select ‘using DHCP’. When selecting “using DHCP”, the IP address, Subnet mask address and Gateway address may not be activated at all. Under DHCP selection, the IP address may be sent to an email address whenever IP 38 MPEG4 NETWORK IP CAMERA User’s Guide address is changed. Users in a local network area may check the IP address through IP installer. NOTE If you select “DHCP”, you may see the rebooting message “Now the Network Camera is rebooting to apply the changes...” on Web Browser. After completing rebooting, Operating Status LED blinks once per second. (You must check whether the Operating Status LED blinks after selecting “DHCP” and rebooting process of camera to ensure your new setting.) To select DHCP, you must have DHCP server in the network. Otherwise, the IP address will be rebooted automatically as the previous IP address. It may take about 4 minutes for booting. 2. Send IP address to e-mail To send camera system information (Camera Name, Camera Location, DHCP IP address), check in a text box and enter your email address. (You should configure your SMTP server information first) 3. Web Server Port Number To set the Port Number for the Web Server.

You may connect external devices such as infrared sensor or alarm sensor to use with the provided terminal block (please refer to Appendix F – The I/O Connector). 43 MPEG4 NETWORK IP CAMERA User’s Guide (1) Trigger Condition This is to select option how to send an event signal to Mpeg4 Network IP Camera. ① Activation of digital input port from…. The Mpeg4 Network IP Camera receives an event signal from external devices such as infrared sensor, alarm sensor etc. ② Motion Detection from…… This is to detect motion from camera by S/W data comparison. When you select “Motion detection”, the Mpeg4 Network IP Camera detects a motion triggered by camera. To detect motion, the camera compares a previous image from present image. When the camera recognizes the data change through comparing the previous image data with present one, then motion detection function is activated. NOTE In a dark place without light, it may never detect the motion because its image wouldn’t be changed at all. ③ Periodically….. The Mpeg4 Network IP Camera itself is to be triggered periodically by setting a certain value from 1 to 3600 seconds. You may set the periodical event time for certain hour like 06:00 to 24:00 by setting 1 o’clock to 24 o’clock. ④ Motion Detection Sensitivity This is to configure the level of motion detection sensitivity. The level is composed of 5 levels from 0 to 4 The higher the level is, the more sensitivity applies. NOTE In case of level 4 for sensitivity, the camera may detect a tiny motion even a light changes, so the event can be trigger so often. In case of level 0 for sensitivity, the camera may not detect a tiny motion. It is strongly recommended to configure it as the level of 1 ~3 for motion detection sensitivity setting in normal condition 44 MPEG4 NETWORK IP CAMERA User’s Guide ⑤ Motion Detection Area This is to configure the motion detection area in the images. Up Middle_Middle Middle Down Left Right Whole Area CAUTION Do not use motion detection function for security purpose because Motion detection function is only developed to use for monitoring purpose. When you want to use it for security purpose, you are asked to use certain sensor such as infrared, motion sensor, etc. to assure your purpose. (2) Image capture option This is to configure image capture option when an event is triggered. When an event occur, you can get the pre-event and post-event image by setting “Before Event” and “After Event”. ① Before Event You may set the starting time to capture image before event is triggered. (Input limitation is from 0 to 30 seconds.) ② After Event You may set the finishing time to capture image after event is triggered. (Input limitation is from 0 to 30 seconds.) ③ Image capture frame rate Set the frame rate from 1 to 15fps when the image is being captured. ④ Image file name You may designate image file name to send Email or FPT after image is captured. All captured image are saved as *.avi file. (Example. “File name 000”.avi) ⑤ Append to the image file name You may append some information to Image file Name Camera IP address A. Camera IP address : Ex) “file name _192.168.1.19.avi B. Date and time : Ex) “file name_20020218150030.avi C. Trigger condition flag 45 MPEG4 NETWORK IP CAMERA User’s Guide In case of choosing “Activation of digital input port”, “D” may be appended to image file name. Ex) “file name_D.avi” In case of choosing “Periodically every…”, “P” is appended to image file name. Ex) “file name_P.avi” D. Image sequence number If you select this option, you may classify the file that has same extend name. Consecutive numbers are from “000” to “999” Ex) When you designate file name as “camera” and select “Image sequence number”, the file name appears “ camera001.avi, camera002.avi ….camera999.avi” Image capture option limitation Configuration for image capture option affects memory capacity. If you configure this option to excess memory size, the warning message “Not enough memory…” appears. The total image capture frame rate must be limited 120 fps due to memory size. (Before event time + After event time) x Image capture frame rate must be under 120. For example, in case you configure “Before event” as 3 seconds, “After event time” as 2 seconds and “image capture frame” as 3fps, the total image capture frame rate is ( 3 + 2) X 3 = 15 fps. If warning message appears, please reduce the value of the option. (3) Trigger Output This is to configure digital output states and control script. Mpeg4 Network IP Camera sends captured image via E-mail or FTP server when connected external sensors detect events. ① External devices signal output This is to supply voltage to output port when events are triggered. (This option is only activated when you select “Activation of digital output” option in previous “Trigger Condition” option.) ② Send alarm to ETSP client This is to send alarm to ETSP client. If you check it in a box, the alarm will be sent to ETSP client when the events are triggered. ③ Send captured image via E-mail This is to designate a person to receive captured image via Email. Mpeg4 Network IP Camera sends captured video to designated E-mail address through SMTP 46 MPEG4 NETWORK IP CAMERA User’s Guide server. You may configure SMTP server and E-mail address where you want to receive. (E-mail address must be composed within 50 bytes. 50 bytes are equal to 50 English characters.) ④ Send captured image to FTP server This is to send captured video from Mpeg4 Network IP Camera when an event is triggered.

To configure Date & Time, it must be reconfigured. 10.Reboot (Restart) Network IP Camera This option will reboot or restart the Camera. Your settings will not be lost. 11.Restore Factory default Values This option will restore the default factory value. 50 MPEG4 NETWORK IP CAMERA User’s Guide Wireless configuration (For wireless Mpeg4 camera only) This screen is used to configure wireless settings to match your access pointer for a wireless network connection. Wireless Setup 1. Use the Connection Mode to determine the type of wireless communication for the Wireless Network IP Camera. There are two choices: Infrastructure Mode and Ad-hoc Mode. The default setting for the Connection Mode is Infrastructure Mode. 2. Set the Service Area Name (SSID) as per the access point setting to which the user wants to connect. 3. The channel is set to channel 1 as a default. In Infrastructure Mode the camera will automatically find the Access Point. The channel only needs to be set in Ad-hoc mode. 4. The default setting for the “Tx rate” is Auto; however, it can be set up to 54 Mbps in 802.11 G mode and upto 11 Mbps in 802.11B mode. 51 MPEG4 NETWORK IP CAMERA User’s Guide Wireless Security Settings: WEP: 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. The WEP key needs to be entered in HEX code. To set up 64-bit WEP, input 10 HEX characters, for example, 0123456789. To setup 128-bit WEP, input 26 HEX characters, for example, 01234567890123456789012345 Authentication: WEP uses two type of authentication method to authenticate the connection request. One is OPEN key authentication in which All clients are allowed to authenticate and second is SHARED key authentication, this mode allows the AP to send the client a challenge text, which the client encrypts and returns to the AP. If the AP successfully decrypts the challenge text, the client is authenticated Set the authentication type as per Access point authentication type. The wireless Mpeg4 Network IP camera’s “Auto” mode automatically switches between open & shared mode. Example 1) Suppose your Access point uses 64-bit encryption, default key 1, Authentication is shared and the key value is 0123456789. Your wireless camera WEP setting will be: 52 MPEG4 NETWORK IP CAMERA User’s Guide Example 2) Your AP uses 128-bit encryption, default key 2, Authentication is shared and the key value is 01234567890123456789012345. Your wireless camera WEP setting will be: Please note: All four WEP Keys need to be set up the exact same way as they are defined in your Wireless Access Point. Make sure the Encryption Code is the same as that of the access point the camera will be connected to under Infrastructure Mode. Your PC’s encryption code also needs to be set up to match the camera’s encryption code under either Infrastructure or Adhoc Mode. The default setting for the Encryption Key is Disable; therefore, to secure the wireless transmission, be sure to enable the Encryption Key by entering the relevant data. NOTE Carefully input the Encryption Code. Any error will cause the communication link to fail 53 MPEG4 NETWORK IP CAMERA User’s Guide IMPORTANT Infrastructure Mode: This is an 802.11 networking framework in which devices communicate with each other by first going through an access point (AP). In infrastructure mode, wireless devices can communicate with each other or can communicate with a wired network. When one AP is connected to a wired network and a set of wireless stations, it is referred to as a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or more BSSs that form a single sub network. Most corporate wireless LANs operate in Infrastructure Mode because they require access to the wired LAN in order to use services such as file servers or printers. Ad-hoc Mode: This is an 802.11 networking framework in which devices or stations communicate directly with each other, without the use of an AP. Ad-hoc Mode is also referred to as Peer-to-Peer Mode or an Independent Basic Service Set (IBSS). Ad-hoc Mode is useful for establishing a network where wireless infrastructure does not exist or where services are not required. SSID (service set identifier): This is a 32-character unique identifier attached to the header of packets sent over a WLAN that acts as a password when a mobile device tries to connect to the BSS. The SSID differentiates one WLAN from another, so all access points and all devices attempting to connect to a specific WLAN must use the same SSID. A device will not be permitted to join the BSS unless it can provide the unique SSID. An SSID is also referred to as a network name because essentially it is a name that identifies a wireless network. To connect a wireless client such as a Wireless Network IP Camera to a specific AP, the user of camera should specify the SSID name in the camera’s wireless IP setting. 54 MPEG4 NETWORK IP CAMERA User’s Guide 7 PoE (Power over Ethernet) Support Power over Ethernet use a single Ethernet cable to transmit both power and data. For PoE to work, the electrical current must go into the data cable at the power-supply end, and come out at the device end, in such a way, as shown below, that the current is kept separate from the data signal so that neither interferes with the other. The current enters the cable by means of a component called an injector. As MPEG4 NETWORK IP CAMERA and NETWORK VIDEO SERVER are IEEE 802.3af Standard PoE compatible, then they will function properly without modification when connected to PoE injector or other PoE supporting network devices directly using standard LAN cable as shown below. Connect to LAN Port of Camera Connect to Ethernet Power over Ethernet (PoE) Injector 55 MPEG4 NETWORK IP CAMERA User’s Guide Appendix A.

By installing Mpeg4 Network IP Camera itself at the desired site, your may monitor views from remote site. 2. What kinds of devices are needed to install? It needs no other equipment except power and network cable. 3. What is maximum transmission speed? Mpeg4 Network IP Camera compresses and transmits 30frames per second on 10 base-T Network. However this speed is not equal to every user. Because transmission is depends on performance of user’s PC and network bandwidth. And there are two viewpoints to calculate transmission speed. The maximum transmission speed is 30 frames per second from user’s viewpoint. However, it does not mean that everyone can receive 30frames peer second. Because transmission speed also depends on user PC performance and network line capacity. Mpeg4 Network IP Camera can transmit to up to 25 users simultaneously. If 5 users are receiving 10 frames per second, the total frames that Mpeg4 Network IP Camera to transmit are 50 frames per second. In this case, Mpeg4 Network IP Camera transmits 50 per second from its viewpoint. And the total size of 50 frames’ images is under the network bandwidth. When Mpeg4 Network IP Camera is on 10 base-T network, the line can transmit 123 frames of 3KB-images per second. 4. What is the maximum number of users to access Mpeg4 Network IP Cameras simultaneously? Mpeg4 Network IP Camera can support up to 40 persons at the same time. The capacity for users is fixed to 35 persons to support already accessed users at rapid transmission speed.

What network Line can be used with Mpeg4 Network IP Camera? All network lines (except telephone lines) can be used, although telephone lines may be used through PCs to connect to Mpeg4 Network IP Camera remotely. Network limes such as xDSL, cable modem. that use dynamic IP addresses require a different installation process than a dedicated line that has a static IP address. 2. What is the maximum extension range of network lines? UTP Cable that is used for the Ethernet can be extended up to 100 meters without bridging. However existing UTP Cable can be extended up to 240 meters without bridging. 3. Does Mpeg4 Network IP Camera need a special rack or case for outdoor use? Originally, Mpeg4 Network IP Camera itself can’t be weatherproofed. Therefore, it has to be equipped with weatherproof case if Mpeg4 Network IP Camera is used for outdoor, like existing CCTV or something. 4. If Mpeg4 Network IP Camera consists of only permanent IP address and several private IP addresses. Can Mpeg4 Network IP Camera be connected to the network with a private IP address? Mpeg4 Network IP Camera can be assigned a private IP address on a network with a permanent IP address. If the network is a Class C network (255.255.255.XXX), then Mpeg4 Network IP Camera may be assigned any available number in the last “room” (represented by XXX). However, since Mpeg4 Network IP Camera is a web server, it can be designated as a local server. Any device on a LAN can be designed as the local server through the router. Designating Mpeg4 Network IP Camera as the local server will make it easier for people outside the LAN to view real-time images form Mpeg4 Network IP Camera. 5. If the network consists of only private IP address, can Mpeg4 Network IP Camera be connected at the network? Mpeg4 Network IP Camera can be connected to LAN having only private IP addresses, but only people on the local network can access Mpeg4 Network IP Camera. Networks with narrow bandwidth may not be able to support several Mpeg4 Network IP Cameras connected simultaneously. 59 MPEG4 NETWORK IP CAMERA User’s Guide 6.

Utilizing IP Addresses on Local Network Introduction Access to the Internet is achieved via Internet IP addresses. Currently, IP addresses are limited. There are 5 classes of networks, and each network contains IP addresses. A network can only hold a limited number of IP addresses. The number of IP addresses depends on the network class. The 5 classes are labeled “A” through “E” with the most common one being the “C” class network. IP Construction and Network Class 1) IP Construction xxx X1 xxx X2 xxx xxx X3 X4 (xxx: 0-255) e.g. 192.168.1.1 2) Network Class A Class: A network that contains IP addresses from 0 to 127 at room ‘X1” Network ID: X1 Host ID: X2, X3, X4 There are 128 A-Class networks in the world. B Class: A network that contains IP addresses from 0 to 127 at room ‘X1” Network ID: X1, X2 Host ID: X3, X4 There are 65, 534 B-Class networks in the world. C Class: A network that contains IP addresses from 192 to 223 at room ‘X1’. Network ID: X1, X2, X3 Host ID: X4 The most common network in the world; there are 2,097,152 C-class networks in the world. D Class: A network that contains IP addresses from 224 to 239 at room ‘X1’. D-class networks are used for multicasting, and are not allowed for common use. E Class: A network that contains IP addresses from 240 to 255 at room ‘X1’. E-class network are reserved. 65 MPEG4 NETWORK IP CAMERA User’s Guide C Class Network 1) Features of Addresses IP address: The three-digit number in room ‘X4’ is for the Host ID. The number ranged from 0 to 255. Among the numbers, 0 is used for Network ID, 1 is used for Router IP (Gateway address) and 255 are used for Broadcast address. The number from 2 to 244 are IP addresses that can be assigned to Mpeg4 Network IP Camera, PC etc. Network ID: Identifies a network. Generally the first number assigned is Network ID. Gateway address: The IP address of the router for connecting Internet and local network. Broadcast address: The IP address for broadcasting. All devices connected on local network have the same Broadcast address. Subnet Mask: Divides a local network into two remote networks. Subnet mask shows the IP quantity in a certain network.

Dynamic Domain Name Server (DDNS) Your internet Service Provider (ISP) provides you at least one IP address which you use to connect to the Internet. The address you get may be static, meaning it never changes, or dynamic, meaning it’s likely to change periodically. Just how often it changes, depends on your ISP. A dynamic IP address complicates remote access since you may not know what your current WAN IP address is when you want to access your network over the Internet. The solution to the dynamic IP address problem comes in the form of a dynamic DNS service. The Internet uses DNS servers to lookup domain names and translates them into IP addresses. Domain names, such as www.intellinte-network.com , are just easy to remember aliases for IP addresses. A dynamic DNS service is unique because it provides a means of updating your IP address so that your listing will remain current when your IP address changes. There are several excellent DDNS services available on the Internet and best of all they’re free to use. Two such several excellent DDNS services are www.ods.org (ODS) and www.DynDNS.org. You’ll need to register with the service and set up the domain name of your choice to begin using it. Please refer the the home page or the service for detailed instructions. A DDNS service works by uploading your WAN IP address to its servers periodically, your gatewayrouter may support DDNS directly, in which case you can enter your DDNS account information into your router and it will update the DDNS servers automatically when your IP address changes. Please consult your router’s documentation for more information. If your router does not support DDNS, you can run a small client utility on any PC on your network which will perform the updating. The client utility is usually provided for free by the service. Check the service’s web page for further information, terms and conditions. 74 MPEG4 NETWORK IP CAMERA User’s Guide How to use ODS DDNS service 1. Get access to ODS homepage (www.ods.org). 2. In case you didn’t register your ID, you should select ‘REGISTER’ menu and then register your ID/ Password. Otherwise, you just login with registered ID/Password. 3. After you register ID/Password normally, you can see ‘Manage’ page. 75 MPEG4 NETWORK IP CAMERA User’s Guide If you want to use normal DDNS service among many services, you should fill in the blanks in a check box and then click “Add Host” button. ① Host: write name you want. ② Domain: Select domain you want. ③ Type: Select ‘A’ (‘A’ is normal) ④ Target: Write initial IP of equipment but just write any IP address that is in the form of “xxx.xxx.xxx.xxx” ⑤ TTL Priority: Do NOT select. This is option. If you want to select “WebView.dyndns.org” for domain name, write ‘WebView’ in Host item and then select dyndns.org for domain. Otherwise, please refer to the premium service. NOTE After completing DynDNS setting, you should set DDNS registration for the Wireless Network IP Camera 76 MPEG4 NETWORK IP CAMERA User’s Guide How to use DynDNS DDNS server 1. Get access to Dyndns homepage (www.dyndns.org). 2. In case you didn’t register your ID, click “Sign Up Now” and then register your ID. Otherwise, you just login with registered ID. 77 MPEG4 NETWORK IP CAMERA User’s Guide 3. Click “Add Host”, and then go to the next page. 78 MPEG4 NETWORK IP CAMERA User’s Guide 4. Enter Domain name you want and just leave other items, and then Click “Add Host” button to register. If you want to know detail of each field, please refer to FAQ of each homepage. 5. You may see this page that shows setting information. after the register is succeeded, NOTE After completing DynDNS setting, you should set DDNS registration for the Network IP Camera 79 MPEG4 NETWORK IP CAMERA User’s Guide DDNS registration for the Mpeg4 Network IP Camera 1. After you set ODS or DynDNS successfully, you should move administration -> network configuration. 2. In DDNS Registration item, select DDNS server (ODS or Dyndns) you want. Enter ID/Password that you registered and fill domain name that you set in each homepage. (ex: intellient.ods.org) Before DDNS setting, you should register ID/ Password and domain name in ODS or Dyndns DDNS service. 3. If register is finished successfully, you may see “Registration Success” in status. Now, you can connect to the Mpeg4 Network IP Camera by a domain name that you registered. 80 MPEG4 NETWORK IP CAMERA User’s Guide I. High Speed Solutions This information is to help you access high-speed Internet services such as xDSL or a cable modem connection. However, most high-speed Internet Services provide you with some external IP addresses, there are several practical issues that should be considered. AVAILABLE IP ADDRESS ISP (Internet Service Provider) will provide you with several external static IP addresses ideally –in which case you can assign any one of these to your Mpeg4 Network IP Camera to make it fully accessible over the Internet. However, if your service provider supplies you with only one IP number – which is often the case – this IP number is normally assigned to your PC-leaving no connection available for your Mpeg4 Network IP Camera. What can you do if your ISP is unable to provide you with an IP number? There are a number of other options what you may like to consider: including: NAT BOX Short for Network Address Translation, NAT (Network Address Translation) is Internet standard that allows a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT box located where your LAN meets the Internet will handle all of the necessary IP address translations and provides: z Internal IP addresses that are unique to your network – with no possibility of conflict with IP Addresses used by other companies and organizations. z The possibility of combining multiple ISDN connections into a single Internet connection. z An effective firewall for hiding internal IP addresses NAT Feature in Windows 2000 Utilize the NAT feature in Windows 2000 to allow multiple Ethernet cards in your PC, and you can then use one of port for the Internet and the other for your internal network. With this solution, you can let your Mpeg4 Network IP Camera upload image streams to an external Web Server that is maintained and located with your ISP. 81 MPEG4 NETWORK IP CAMERA User’s Guide ROUTERS AND FIREWALLS Another solution is to use one of several small routers/firewalls currently available on the market. These provide the necessary NAT functionality and allow complete independence for your PC, which can be switched off or rebooted without affecting the image transmission from your Mpeg4 Network IP Camera. WINGATE SERVER SOFTWARE: Running on a single Windows 95/98/2000 or NT computer, this software allows multiple users simultaneous access to the Internet through a LAN or higher-speed line, such as xDSL or cable modem connection; and effectively shares a single Internet connection with almost any type of client computer running TCP/IP. For more advanced users, the WinGate 3.0 Standard and Pro versions also allow the administrator to change the IP bindings so that external requests may be routed specifically to your Mpeg4 Network IP Camera – running behind the WinGate software. NOTE NAT, or Network Address Translator, Virtual LAN) A hardware device currently being developed and used to extend the Internet addresses already in use. NAT has been suggested as an alternative to adopting IPv6 (IPng). It allows duplicate IP addresses to be used within a corporation and unique addresses outside. It is defined in RFC 1631. 82 MPEG4 NETWORK IP CAMERA User’s Guide J. Reinstating the Factory Default Settings This information explains instructions in detail on how to set the default settings in the Mpeg4 Network IP Camera.

Then,[Mpeg4 Network IP Camera Boot] prompt shows like the below image. 83 MPEG4 NETWORK IP CAMERA User’s Guide ④ When you enter ‘set’, Administrator ID & Password reinstate as factory default ‘admin’ NOTE Reinstating the original default settings will cause all parameters (Including IP address) to be reset. Factory default setting Administrator ID: admin Administrator Password: admin Guest ID: guest Guest Password: guest IP Address: 192.168.1.221 Subnet Mask Address: 255.255.255.0 Gateway Address: 192.168.1.1 Server IP Address: 192.168.1.5 84 MPEG4 NETWORK IP CAMERA User’s Guide K. Glossary of Terms ActiveX – A control (or set of rules) used by a browser. ActiveX controls are often downloaded and installed automatically as required. ARP – Address Resolution Protocol. A method for finding a host's Ethernet address from its Internet address. The sender broadcasts an ARP packet containing the Internet address of another host and waits for it (or some other host) to send back its Ethernet address. Each host maintains a cache of address translations to reduce delay and loading. ARP allows the Internet address to be independent of the Ethernet address but it only works if all hosts support it. The ARP command can be used to set the IP – addresses for your product. CGI – A standard for running external programs from a World-Wide Web HTTP server. CGI specifies how to pass arguments to the executing program as part of the HTTP request. It also defines a set of environment variables. Commonly, the program will generate some HTML which will be passed back to the browser but it can also request URL redirection. A set of rules (or a program) that allows a Web Server to communications with other programs. DSL – Digital Subscriber Loop, A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and telephone companies. DHCP - A protocol that provides a means to dynamically allocate IP addresses to computers on a local area network. The system administrator assigns a range of IP addresses to DHCP and each client computer on the LAN has its TCP/IP software configured to request an IP address from the DHCP server. The request and grant process uses a lease concept with a controllable time period. Ethernet –A widely used networking standard. Firewall –A virtual barrier between a LAN (Local Area Network) and other networks, e.g. the Internet. Frame Grabber Card – Plug-in hardware for “grabbing” images. FTP - A client-server protocol that allows a user on one computer to transfer files to and from another computer over a TCP/IP network. Also the client program the user executes to transfer files. It is defined in STD 9, RFC 959. 85 MPEG4 NETWORK IP CAMERA User’s Guide HTML - A markup language used to structure text and multimedia documents and to set up hypertext links between documents, used extensively on the World Wide Web. HTTP - A protocol used to request and transmit files, especially WebPages and WebPages components, over the Internet or other computer network. Intranet - A privately maintained computer network that can be accessed only by authorized persons, especially members or employees of the organization that owns it. IP – Internet Protocol. The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. It provides packet routing, fragmentation and re-assembly through the data link layer. IP number (address) – A unique number used by a computer on the network to allow it to be identified and found. JPEG – A standard image format, used widely for photographs. Also known as JPG. LAN – Local Area Network. A data communications network which is geographically limited (typically to a 1 km radius) allowing easy interconnection of terminals, microprocessors and computers within adjacent buildings. Ethernet and FDDI are examples of standard LANs. PING - A protocol that sends a message to another computer and waits for acknowledgment, often used to check if another computer on a network is reachable. PPP – Point–to–Point Protocol. A method allowing one computer to connect to another, usually via a modem over a phone line. Protocol - A set of formal rules describing how to transmit data, especially across a network. Low-level protocols define the electrical and physical standards to be observed, bit- and byte-ordering and the transmission and error detection and correction of the bit stream. High-level protocols deal with the data formatting, including the syntax of messages, the terminal to computer dialogue, character sets, sequencing of messages etc. SMTP – Simple Mail Transfer Protocol 86 MPEG4 NETWORK IP CAMERA User’s Guide TCP/IP - Transmission Control Protocol/Internet Protocol. The wide-area-networking protocol that makes the Internet work. TCP/IP is used on many networks, including the Internet. TCP keeps track of the individual packets of information and IP contains the rules for how the packets are actually sent and received. URL – Uniform Resource Locator. An “address” on the network. WAN – Wide–Area–Network. A communications network that uses such devices as telephone lines, satellite dishes, or radio waves to span a larger geographic area than can be covered by a LAN.
