See also TCP.

IP address - An IP address is simply an address on an IP network used by a computer/device connected to that network. IP addresses allow all the connected computers/devices to find each other and to pass data back and forth.

To avoid conflicts, each IP address on any given network must be unique. An IP address can be assigned as fixed, so that it does not change, or it can be assigned dynamically (and automatically) by DHCP.

An IP address consists of four groups (or quads) of decimal digits separated by periods, e.g. 130.5.5.25. Different parts of the address represent different things. Some part will represent the network number or address, and some other part will represent the local machine address. See also IP (Internet Protocol).

Inputs/Outputs (I/Os) - The digital I/Os on, for example, a network camera can be used to connect any device that can toggle between an open and a closed circuit.

For example, if a door switch is used as an input device, opening the door could trigger the upload of video images and the sending of notification messages.

An output might, for example, be used to automatically start a siren when there is a motion detection trigger.

I-VOP- See VOP.

JPEG (Joint Photographic Experts Group) - Together with the GIF file format, JPEG is an image file type commonly used on the web. A JPEG image is a bitmap, and usually has the file suffix '.jpg' or “.jpeg”. When creating a JPEG image, it is possible to configure the level of compression to use. As the lowest compression (i.e. the highest quality) results in the largest file, there is a trade-off between image quality and file size.

kbit/s (kilobits per second) - A measure of the bit rate, i.e. the rate at which bits are passing a given point. See also Bit rate.

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

Linux - Linux is an open source operating system within the UNIX family. Because of its robustness and availability, Linux has won popularity in the open source community and among commercial application developers.

Lux - A standard unit of illumination measurement.

MAC address (Media Access Control address) - A MAC address is a unique identifier associated with a piece of networking equipment, or more specifically, its interface with the network. For example, the network card in a computer has its own MAC address.

Manual iris - This is the opposite of an auto iris, i.e. the

AXIS 233D - Glossary 75

camera iris must be adjusted manually to regulate the amount of light allowed to reach the image sensor.

Mbit/s (Megabits per second) - A measure of the bit rate, i.e. the rate at which bits are passing a given point. Commonly used to give the “speed” of a network. A LAN might run at 10 or 100 Mbit/s. See also Bit rate.

Monitor - A monitor is very similar to a television set, but lacks the electronics to pick up regular television signals.

Motion JPEG - Motion JPEG is a simple compression/decompression technique for network video. Latency is low and image quality is guaranteed, regardless of movement or complexity of the image. Image quality is controlled by adjusting the compression level, which in turn provides control over the file size, and thereby the bit rate.

High-quality individual images from the Motion JPEG stream are easily extracted. See also JPEG and GIF.

Megapixel - See Pixel.

MPEG (Moving Picture Experts Group) - The Moving Picture Experts Group develops standards for digital video compression. It operates under the auspices of the International Organization for Standardization (ISO). The MPEG standards are an evolving series, each designed for a different purpose.

MPEG-2- The designation for a group of video coding standards, and is typically used to encode video for broadcast signals, including digital satellite and Cable TV. MPEG-2, with some modifications, is also the coding format used by standard commercial DVD movies.

MPEG-4- MPEG-4 is a group of video coding standards and related technology. The primary uses for the MPEG-4 standard are web (streaming media) and CD distribution, conversational (videophone), and broadcast television.

Most of the features included in MPEG-4 are left to individual developers to decide whether to implement them or not. This means that there are probably no complete implementations of the entire MPEG-4 set of standards. To deal with this, the standard includes the concept of “profiles” and “levels”, allowing a specific set of capabilities to be defined in a manner appropriate for a subset of applications.

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

Network camera (Network video camera) - A network camera is a camera and computer combined in one intelligent unit. It captures and sends live video directly over an IP network such as a LAN, intranet or the Internet. Users can view and/or manage the camera using a standard web browser or application software from any local or remote computer on a network. The camera allows multiple authorized viewers from different

233D specifications

Axis Communications, a pioneer in the field of network video solutions, has continually pushed the envelope in surveillance technology with its innovative products. Among its esteemed offerings, the Axis 233D stands out as a formidable tool for both security professionals and organizations seeking comprehensive monitoring solutions.

The Axis 233D is a high-performance PTZ (Pan-Tilt-Zoom) network camera designed for demanding surveillance environments. One of its main features is the ability to provide high-resolution video streaming at 30 frames per second, ensuring that users can capture clear and detailed images, even in dynamic situations. This camera supports a resolution of up to 2 megapixels, which enhances its ability to deliver crisp visuals, crucial for identifying individuals and objects in the monitored areas.

Equipped with advanced pan, tilt, and zoom capabilities, the Axis 233D can cover expansive areas with ease. The camera offers a 360-degree endless rotation for pan movements and a wide field of view, making it ideal for large spaces like parking lots, shopping centers, and public transport stations. The powerful zoom lens allows operators to focus on specific subjects from a distance, which is essential in security monitoring.

The Axis 233D also employs robust technologies to ensure excellent performance in various lighting conditions. With integrated WDR (Wide Dynamic Range), this camera can balance scenes with significant contrasts in lighting, ensuring that both bright and dark areas are clearly visible. Additionally, features like digital noise reduction contribute to clearer images in low-light situations, making it versatile for day and night operation.

Another characteristic that sets the Axis 233D apart is its network functionality. This camera supports Power over Ethernet (PoE), simplifying installation as it requires only a single Ethernet cable for both power and data transfer. It also leverages Axis' advanced video compression technologies, including H.264, which optimizes bandwidth usage while maintaining high image quality.
