Glossary of Terms

ActiveX - A control (or set of rules) used by a browser. ActiveX controls are often downloaded and installed automatically as required.

AMC - AXIS Media Control. The control required for viewing video images in Internet Explorer. Installs automatically on first use.

API - Application Programming Interface. The Axis API can be used for integrating Axis products into other applications.

ARP - Address Resolution Protocol. A protocol used to associate an IP address to a hardware MAC address. A request is broadcast on the local network to find out what the MAC address is for the IP address.

ARTPEC - Axis Real Time Picture Encoder - used for video image compression.

CCD - Charge Coupled Device. CCD is one of the two main types of image sensors used in digital cameras. When a picture is taken, the CCD is struck by light coming through the camera’s lens. Each of the thousands or millions of tiny pixels that make up the CCD convert this light into electrons.

CGI - Common Gateway Interface. A set of rules (or a program) that allows a Web Server to communicate with other programs.

Client/Server - Describes the network relationship between two computer programs in which one, the client, makes a service request from another - the server.

DC-Iris - This special type of iris is electrically controlled by the Axis camera, to automatically regulate the amount of light allowed to enter.

DNS - The Domain Name System (DNS) locates and translates Internet domain names into IP (Internet Protocol) addresses.

Ethernet - A widely used networking standard. ETRAX - Axis' own microprocessor.

Firewall - A virtual barrier between a LAN (Local Area Network) and other networks, e.g. the Internet.

FTP - File Transfer Protocol. Used for the simple transfer of files to and from an FTP-server.

Full-duplex- Transmission of data, e.g. audio, in two directions simultaneously.

HTML - Hypertext Mark-up Language. Used widely for authoring documents viewed in web browsers.

HTTP - Hypertext Transfer Protocol. The set of rules for exchanging files (text, images, sound, video, and other files) on the World Wide Web.

HTTPS - Hypertext Transfer Protocol over Secure Socket Layer. A web protocol that provides encryption for page requests from users and for the pages returned by the web server.

Intranet - A private network limited to an organization or corporation. Usually closed to external traffic.

IP - Internet-Protocol. See TCP/IP.

IP address - A unique number used by a network device, to allow it to be identified and found on the network. The 32-bit IP address is made up of four groups (or quads) of decimal digits separated by periods. An example of an IP address is: 192.168.0.1

ISMA - Internet Streaming Media Alliance

JPEG - A standard image format, used widely for photographs. Also known as JPG.

LAN - A local area network (LAN) is a group of computers and associated devices that typically share common resources within a limited geographical area.

Linux - A popular operating system, which is “open source” and practically free of charge.

Lux - A standard unit for the measurement of light, where 1 Lux equals the light emitted from a single candle at a distance of one meter.

Mbit/s - Megabits per second. A unit for measuring speeds in networks. A LAN might run at 10 or 100 Mbit/s.

MPEG-4- A video compression standard that makes good use of bandwidth, and which can provide high-quality video streams at less than 1 Mbit/s.

Multicast - A bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of information to multiple network recipients.

NTSC - National Television Standards Committee. NTSC is the standard format used for televisions in most of North and Central America, and Japan.

NWAY - A network protocol that automatically negotiates the highest possible common transmission speed between two devices.

PAL - Phase Altering Line. PAL is the standard format used for televisions in most of the world (other than the US, Canada, and Japan).

PEM - Privacy Enhanced Mail. An early standard for securing electronic mail. The PEM-format is often used for representing an HTTPS certificate or certificate request.

Ping - A small utility used for sending data packets to network resources to check that they are working and that the network is intact.

Axis Communications 225FD user manual Glossary of Terms

225FD specifications

Axis Communications, a pioneer in network video solutions, continues to innovate with the introduction of the Axis 225FD, a cutting-edge fixed dome network camera designed to enhance surveillance capabilities in various environments. This device strives to meet the demanding requirements of modern security by combining advanced imaging technology with user-friendly features.

One of the standout characteristics of the Axis 225FD is its exceptional image quality. It boasts a high-resolution sensor capable of capturing detailed images even in low light conditions. This is further enhanced by Axis' Wide Dynamic Range (WDR) technology, which ensures that both bright and dark areas within a scene are clearly visible. This feature is particularly useful in dynamic lighting situations, such as entryways where bright sunlight may contrast with shaded areas.

The Axis 225FD is equipped with a built-in microphone to capture audio along with video, adding another layer of context to footage. This feature is invaluable for various applications, allowing security personnel to not only see but also hear events as they unfold, leading to more comprehensive situational awareness.

For adaptability, the camera supports PoE (Power over Ethernet), simplifying installation by allowing both power and data transfer through a single cable. This efficiency means less clutter and easier setup, making the Axis 225FD suitable for diverse installation environments, including retail spaces, offices, and public areas.

In terms of security features, the Axis 225FD supports multiple streams, enabling different resolutions for different scenarios. This flexibility ensures that users can tailor the video quality based on their bandwidth constraints while maintaining critical surveillance capabilities. Moreover, the camera is equipped with tampering alarms that send notifications if it is moved or obstructed, further bolstering security measures.

Durability is another critical consideration with the Axis 225FD. Designed to withstand the rigors of various environments, the camera is housed in a robust casing that protects it from dust and moisture, meeting IP66 and IK08 standards. This resilience ensures that the camera remains operational in challenging conditions, providing reliable surveillance year-round.

In summary, the Axis Communications 225FD is a state-of-the-art surveillance solution that excels in key areas such as image quality, audio capture, installation flexibility, and security features. With its durable design and advanced technologies, it stands out as a top choice for organizations looking to enhance their monitoring capabilities and ensure the safety of people and assets.
