The Axis 232D Color Network Dome Camera offers pan/tilt and zoom control over IP networks such as a LAN or the Internet, making it ideal for demanding surveillance and remote monitoring applications. With advanced event-management functionalities and daytime/nighttime functionality, the Axis 232D is perfect for professional security installations at airports, railway stations and prisons, as well as at warehouses, manufacturing facilities, shopping centers and schools.
The Axis 232D is a digital network camera that distributes superior-quality live video over an intranet or the Internet. With a built-in Web Server, the Axis 232D allows remote surveillance by up to 20 simultaneous users from any browser (or browsers) on the network. This unit also provides full Web-based control of its many security, management and configuration functions, as well as its pan/tilt and zoom functions. This network camera connects directly to networks via a 10/100 BaseT/TX Ethernet connection, for faster and more secure service.
This camera utilizes a high-end 0.25-inch Sony ExView HAD CCD (charge-coupled device) sensor, with a resolution of 768-by-576 pixels. The 232D includes an IR-cut (Infrared) filter that can be automatically or manually removed, depending on light conditions. This enables the camera to capture color video with the filter on in light conditions down to 0.3 Lux, and black and white video with the filter removed in conditions down to 0.005 Lux. The Axis 232D comes with a motorized lens with a range of 4.1 to 73.8 millimeters, which allows it to auto focus at up to 18x optical and 12x digital zoom. The unit's 32-bit CPU, automatic or manual fixed white balance, and exposure times ranging from one to 1/10,000 of a second, ensuring a high picture quality. With 10 user-controlled video compression levels generating high-quality motion-JPEG video and MPEG4, this camera can provide a frame rate of up to 30 frames-per-second (frames per second), equivalent to a 460-NTSC analog video. The Axis 232D has 32 MB of RAM, nine megabytes of which are available for pre/post alarm storage equivalent to two minutes of video, and eight megabytes of internal flash memory that allows for simple firmware upgrades. Powered via a 24-volt external power cord (included), it can operate in temperatures from five to 50-degrees Celsius.
Supporting TCP/IP, HTTP,and FTP protocols, the Axis 232D can be configured and managed via its own simple Web-based administration tools through the use of a regular browser, and can be used in mixed environments such as Windows, Macintosh, and Linux. This camera has a horizontal viewing angle from 48 to 2.8 degrees, and features a true-dome range of motion with a 360-degree pan range and 0 to 90 degree tilt range, at a pan/tilt speed of more than 360-degrees a second. This camera also features image customization and 20 position presets. It also features scheduled and triggered event functionality with preset call-up and alarm notification via e-mail, TCP, or HTTP. The Axis 232D includes input/output connections for four alarm inputs and four alarm outputs.
Because of the Axis 232D's self-contained Web server, your digital video can be secured like any other Internet host. Using the unit's robust security settings, which includes support for multi-user password protection, HTTPS Encryption and IP address, filtering an administrator can assign whether individuals, groups, a whole company or the whole world can access the camera. In order to ensure maximum reliability and ease of use, the Axis 232D is based on the Linux 2.4-kernel operating system and includes software developed by the OpenSSL project, giving users access to free, open-source functionality.
In a word, this Axis dome camera is a reliable, economical and high-quality monitoring system ideally suited for nighttime security surveillance and designed to be used over the Internet or internal networks. Suitable for both indoor and outdoor, as well as daytime and nighttime applications, the 232D should be installed overhead and comes with both hard-ceiling and drop-ceiling mounting brackets. However, the CCD sensor may become permanently damaged if exposed to long hours of direct sunlight or halogen light. This camera is optimized for use with Internet Explorer 5.x or later, but does support both Mozilla Firefox 1.4 and Netscape 7.1 or later, albeit with some limitations in functionality.

About Surveillance Camera Technical Features
Lux rating is the measurement used to indicate how sensitive a camera is to light, and stands for the level of light reflected off a piece of paper by a candle from one meter away. Thus a sensitivity of three Lux would mean a camera could generate an acceptable picture of a piece-of-paper-sized object that was illuminated by the equivalent of three candles from one meter away. The lower the Lux level, the better the camera's ability to work in low-light conditions. The camera's resolution should be greater than or equal to the resolution supported by the system's recorder or monitor. The S/N, or signal to noise ratio, is an important measure of a camera's quality. A poor camera, low-light conditions or poor wiring causes "noise" which consumes processing power and disk space. A camera with a wide dynamic range is ideal, especially for recording areas in which both indoor and outdoor light are present. CCD (charge-coupled device) sensors provide high-quality images that are less susceptible to noise. CMOS (complimentary metal-oxide semiconductor) sensors offer less image quality, but are usually more cost-effective and energy efficient.
About IP Cameras
An IP camera can be used to project images and video directly through a computer's Web browser for remote monitoring. An IP camera, unlike a web cam, contains the IP and Web page within it and can often be added to a network without additional configuration or software. Combined with a network video recorder, an IP camera can be used to construct a reliable video surveillance system.
About Pan/Tilt Cameras
A Pan/Tilt Camera has the ability to pan ("move" horizontally), or tilt ("move" vertically). IP cameras often have pan/tilt capability. A pan/tilt camera is ideal for monitoring of situations that need a continual real-time adjustment of the views.
About Infrared Cameras
An infrared camera uses an infrared illuminator for low-light and nighttime viewing. Typically designed with fixed focal lengths, infrared cameras provide black and white images of nighttime viewing, and many have color capability for daylight use.
About Dome Cameras
A dome camera is one of the most common indoor security camera styles. Mounted on the ceiling, and often built to be tamper-resistant, dome cameras are designed to be visually appealing and more secure than other types of security cameras. A true dome camera enables a continuous 360-degree pan and 90-degree tilt operation, providing for extensive room coverage. One disadvantage of dome cameras is that they usually are not suitable for low-light conditions and must be used in well-lit areas.
