Glossary

Active Speaker - a speaker with a built-in power amplifier.

ActiveX - ActiveX is a standard that enables software components to interact with one another in a networked environment, regardless of the language(s) used to create them. Web browsers may come into contact with ActiveX controls, ActiveX documents, and ActiveX scripts. ActiveX controls are often downloaded and installed automatically as required.

AMC (AXIS Media Control) - AMC is the ActiveX component required to view moving images from an Axis video device in Internet Explorer. The component is installed automatically on the viewing computer on first use. Once installed, AMC can be configured from Windows Control Panel.

Analog video camera - The signal from an analog video camera is viewed directly on e.g. a monitor in the analog system, which depends on traditional analog cabling.

Alternatively, the signal can be digitized with the use of a video server, and can then be made available over a data (IP) network.

ARP (Address Resolution Protocol) - This protocol is used to associate an IP address to a hardware MAC address. A request is broadcast on the local network to discover the MAC address for an IP address.

ARTPEC-2 (Axis Real Time Picture Encoder) - A chip designed by Axis for image compression. ARTPEC supports a range of CCD and CMOS sensors, built-in functionality for sharpening, backlight compensation, noise reduction and white balance, support for multiple Motion-JPEG streams, support for MPEG-4 part 2, up to 30 frames/second from 4 simultaneous video sources and real-time compression of up to 45 Megapixels/second.

ASIC (Application Specific Integrated Circuit) - A circuit designed for a specific application, as opposed to a general purpose circuit, such as a microprocessor.

Aspect ratio - A ratio of width to height in images. A common aspect ratio used for television screens and computer monitors is 4:3. High-definition television (HDTV) uses an aspect ratio of 9:16.

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

AXIS Internet Dynamic DNS Service - This free service provides an Axis network product with a unique DNS or domain name (URL address), which can then be used instead of an IP address to access the product from a web browser.

AXIS IP Utility - A tool for discovering and setting IP addresses for Axis network devices. AXIS IP Utility is

supplied free of charge by Axis.

AXIS Camera Management - A powerful and efficient installation and management tool for Axis network video products. The tool can automatically find and set IP addresses, show connection status and manage firmware upgrades of multiple devices.

Bitmap - A bitmap is a data file representing a rectangular grid of pixels. It defines a display space and color for each pixel (or “bit”) in the display space. This type of image is known as a “raster graphic”. GIFs and JPEGs are examples of image file types that contain bitmaps. Because a bitmap uses this fixed raster method, it cannot easily be rescaled without losing definition. Conversely, a vector graphic image uses geometrical shapes to represent the image, and can thus be quickly rescaled.

Bit rate - The bit rate (in kbit/s or Mbit/s) is often referred to as speed, but actually defines the number of bits/time unit and not distance/time unit.

Bonjour - Also known as zero-configuration networking, Bonjour enables the automatic discovery of computers, devices, and services on IP networks. Bonjour allows devices to automatically discover each other without the need to enter IP addresses or configure DNS servers. Bonjour is developed by Apple Computer Inc.

BOOTP (Bootstrap Protocol) - A protocol that can automatically configure a network device (give it an IP address). BOOTP is the basis for a more advanced network management protocol, the Dynamic Host Configuration Protocol (DHCP).

CCD (Charged Coupled Device) - This light-sensitive image device used in many digital cameras is a large integrated circuit that contains hundreds of thousands of photo-sites (pixels) that convert light energy into electronic signals. Its size is measured diagonally and can be 1/4”, 1/3”, 1/2” or 2/3”.

CCTV (Closed Circuit Television) - A CCTV system is a closed/private video system, usually constructed with coaxial cabling, and used within a single building/group of buildings. It is used to visually monitor the location for security or industrial purposes. Video from the CCTV system can be recorded and viewed on-site or remotely.

CCTV video camera - A traditional CCTV video camera is an analog camera, available in both monochrome (black and white) and color. Cameras can be set in fixed positions or placed on “Pan/Tilt/Zoom” devices, which allow the camera to be maneuvered. Using a zoom lens provides a closer view of the object being viewed. CCTV analog video cameras can be viewed over a computer network by using a video server.

CGI (Common Gateway Interface) - A specification for communication between a web server and other (CGI) programs. For example, a HTML page that contains a form

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.

Furthermore, the Axis 233D is embedded with intelligent video analytics, enabling proactive monitoring. Functions such as motion detection and object tracking help users respond quickly to potential security threats. This capability is critical in real-time environments where each moment counts.

In summary, the Axis Communications 233D is a high-end surveillance solution that marries advanced technology with user-friendly features. With its PTZ functionalities, exceptional image quality, robust performance in varying light conditions, and intelligent analytics, it serves as an indispensable asset for security professionals looking to enhance their surveillance systems effectively. As security needs continue to evolve, the Axis 233D remains at the forefront of addressing those challenges.
