54AXIS 225FD - Glossary of Terms

Pre/post alarm image - The images from immediately before and after an alarm.

Privacy mask - An image or specified area used to block out certain parts of the video image.

Protocol - A special set of rules governing how two entities will communicate. Protocols are found at many levels of communication, and there are hardware protocols and software protocols.

Router - A device that determines the next network point to which a packet should be forwarded on its way to its final destination. A router is often included as part of a network switch (see below).

RTP- Real-Time Transfer Protocol. A transfer protocol designed for delivery of live contents, e.g. MPEG-4.

Simplex - In simplex operation, a network cable or communications channel can send information in one direction only.

SMTP - A common e-mail protocol.

SNMP - Simple Network Management Protocol. An application layer protocol that facilitates the exchange of management information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite.

Subnet Mask - An IP address consists of two components: the network address and the host address. “Subnetting’ enables a network administrator to further divide the host part of the address into two or more subnets. The subnet mask identifies the subnet to which an IP address belongs.

Switch - Whilst a simple hub transmits all data to all devices connected to it, a switch only transmits the data to the device it is specifically intended for.

TCP/IP - Transmission Control Protocol/Internet Protocol. A suite of network protocols that determine how data is transmitted. TCP/IP is used on many networks, including the Internet. TCP keeps track of the individual packets of information and IP contains the rules for how the packets are actually sent and received.

UDP - The User Datagram Protocol is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP) and, together with IP, is also known as UDP/IP.

Unicast - Communication that takes place over a network between a single sender and a single receiver.

UPnPTM - Allows the automatic peer-to-peer detection of devices on the network.

URL - Uniform Resource Locator. An “address" on the network.

Varifocal - A varifocal lens provides a wide range of focal lengths, as opposed to a lens with a fixed focal length, which only provides one.

WAN - Wide-Area-Network. Similar to a LAN, but on a larger geographical scale.

Web server - A program on a computer (server) providing the resources (e.g. web pages) requested by the user (client).

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.
