Alarm Input This facility allows various forms of external alarms, such as door contact, reed switched, Passive Infra-red detector, or vibration sensors, to be connected to the security camera. As receiving an alarm signal, the specific camera will be switch on.

Analog Signal Analog signals are continuous rather than discrete or pulsed, varying in voltage, frequency, or phase of qu antities.

Angle of view Also known as viewing angle, this refers to the available angular range within a certain image size. The smaller the focal length, the wider the angle of view is.

Aspect Ratio Aspect Ratio refers to the ratio of width to height in images. 4:3 is a common aspect ration used in television screens and computer monitors.

Vertical resolution Contrast with horizontal resolution, vertical resolution defines the number of elements, such as rows, dots, or lines, from the top to the bottom in an image.

Video compression The “compression” technology means packing the information into a smaller space. Under many situations the video signal takes up a lot of space and results in the demanding requirement of bit rate and file size. The “compression” of video helps reduce bit rates, bandwidth, and smaller file size and facilitates the Internet transmission.

Video intercom Used at door entryways, this system utilizes audio and video for communication or movement control of people.

Video server This device enables an analog camera to be converted into an IP one, digitalizing the analog signals into digital images and transferring via an Internet Protocol Network such as Intranet, LAN, or ,ISDN connection. Therefore, an analog surveillance system can be upgraded to an IP-based surveillance system.

Video streaming Streaming video delivers compressed content over the Internet in the form of packets. It is unnecessary for users to download the entire file to view it. Instead, users may watch the real-time image as downloading. It requires a player to decompress the signal and deliver it to the display and audio data to a speaker.

Video surveillance This term refers to the deployment of CCTV, IP camera, NVR, and DVR to monitor activities in different locations for security purpose.

VPN

VPN refers to Virtual Private Network. This network uses a public telecommunication infrastructure, such as the Internet, to offer remote secure access to the private network. The work of VPN allows the use of public infrastructure while maintaining the privacy (e.g. encryption) of individual use through specific procedures or via special protocols.

Video Motion Detection

This device can define activity in a scene by analyzing the differences in the image. The common way is triggering an alarm after detecting the unusual movement.

WAN This term stands for Wide Area Network. It is a communications network spanning a large geographical area, connecting multiple metro area networks (MAN) or local area networks (LAN). The Internet is a WAN.

White balance This function helps adjust the color to ensure a more realistic picture.

Wide angle lens This type of lens have a short distance between point of focus and the optical center and enable a wide horizontal field of view.

Wireless This type of transmission uses the electromagnetic waves instead of wires to carry the signal for delivery.

W-LAN (Wireless LAN)

This term is short for Wireless LAN. A wireless LAN is a wireless local area network that mobile users can connect to LAN via wireless connection.

Web server

A web server is a program, which allows Web browsers to possess the files requests. The operation is that the Web serv er listens for requests from Web browsers and upon receiving a request for a file sends it back to the browser. Also, the Web server is a repository of data and content, which is actually a database.

WEP (Wireless Equivalent Privacy)

WEP is short for Wireless Equivalent Privacy. This is a wireless security protocol, specified in the IEEE 802.11b standard, which is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to that usually expected of a wired LAN.

WPA-PSK (Wi-Fi Protected Access-Pre-Shared Key)

WPA-PSK stands for Wi-Fi Protected Access-Pre-Shared Key; basically it is an authentication mechanism in which users provide some form of credentials to verify that they should be allowed access to a network. The encryption mechanisms for WPA and WPA-PSK are the same. The only difference is that the authentication in WPA-PSK is reduced to a simple password, instead of user-specific credentials.

Web browser

This is basically a software program used for reaching various kinds of information on the Web.
