DOD MyCam2 [75/76] Glossary of terms

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/n: 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/n

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 (W PA and W PA2) 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.
