GLOSSARY OF TERMS 
1. Network Camera: A stand-alone device which allows users to view live, full motion video from anywhere 
on a computer network, even over the Internet, using a standard web browser.   
2. JPEG: A standard image format, used widely for photographs, also known as JPG.   
3. IEEE 802.11b/g: The specifications developed by the IEEE for wireless network technology. It provides 
11 Mbps transmission in the 2.4GHz band usage.   
4. WEP: Wireless Equivalent Privacy. A security protocol for wireless network defined in the IEEE 802.11b/g 
standard. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is 
transmitted from one end point to another.   
5. Adhoc Mode: A wireless network system in which devices communicate directly with each other, without 
the use of a wireless router.   
6. Infrastructure Mode: One of the wireless network system in which devices communicate with each other 
by first going through the wireless router.   
7. IP Address: The unique 32 bit number assigned to each computer connected to the Internet. IP numbers 
are used by the TCP/IP protocol to route packets of data to their destinations.   
8. TCP/IP: The collection of "protocols" underlying the functioning of the Internet. Each computer connected 
to the Internet is identified by a unique IP Address.   
9. SMTP: Simple Mail Transfer Protocol.   
10. FTP: File Transfer Protocol. Network cameras equipped with an embedded operating system, such as 
Linux, can use FTP to send images to a website. 
11. DHCP: Dynamic Host Configuration Protocol is a set of rules used by communications devices such as 
a computer, router or network adapter to allow the device to request and obtain an IP address from a server 
which has a list of addresses available for assignment.   
12 UPnP: Universal Plug and Play is an architecture for pervasive peer-to-peer network connectivity of 
intelligent appliances and wireless devices.   
13. DDNS: DDNS is a method of keeping a domain name linked to a dynamic IP address with your Network 
Camera. You can set up your DDNS service and the device will automatically update your DDNS server 
each time it alter a different IP address.   
14. Time server: A time server consists of a computer networking device that reads the actual time from a 
reference clock and distributes this information to its clients using a computer network. 
15. WPA:
 Wi-Fi Protected Access (WPA and WPA2) is a class of systems to secure wireless (Wi-Fi) 
computer networks. WPA implements the majority of the IEEE 802.11i standard, and was intended as an 
intermediate measure to take the place of WEP while 802.11i was prepared.
