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.
