AXIS 231D+/232D+ - Video Streams 11

Video Streams

The AXIS 231D+/232D+ provides several different image and video stream formats. The type to use depends on your requirements and on the properties of your network.

The Live View page in the AXIS 231D+/232D+ provides access to Motion JPEG and MPEG-4 video streams, as well as to single JPEG images. Other applications and clients can also access these video streams/images directly, without going via the Live View page.

Stream Types

Motion JPEG

This format uses standard JPEG still images in the video stream. These images are then displayed and updated at a rate sufficient to create a stream that shows constantly updated motion.

The Motion JPEG stream uses considerable amounts of bandwidth, but also provides excellent image quality and access to every image contained in the stream.

Note also that multiple clients accessing Motion JPEG streams can use different image settings.

MPEG-4

This is a video compression standard that makes good use of bandwidth, and which can provide high quality video streams at less than 1 Mbit/s.

Notes: • MPEG-4 is licensed technology. The AXIS 231D+/232D+ includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.

• All clients viewing the MPEG-4 stream must use the same image settings.

The MPEG-4 standard provides scope for a large range of different coding tools for use by various applications in different situations, and the AXIS 231D+/232D+ provides certain subsets of these tools. These are represented as Video object types, which are selected for use with different viewing clients. The supported video object types are:

•Simple - sets the coding type to H.263, as used by QuickTime™, for example.

•Advanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC (AXIS Media Control).

When using MPEG-4 it is also possible to control the bit rate, which in turn allows control of bandwidth usage. CBR (constant bit rate) is used to achieve a specific bit rate by varying the quality of the MPEG-4 stream. When using VBR (variable bit rate), the quality of the video stream is kept as constant as possible, at the cost of a varying bit rate.

232d+ specifications

Axis Communications, a leading provider of IP security solutions, offers a range of high-performance cameras designed for various surveillance applications. Among their products, the Axis 232D+ and Axis 231D+ stand out for their robust features and advanced technologies, making them suitable for both indoor and outdoor environments.

The Axis 232D+ is a high-speed dome camera that delivers exceptional video quality, thanks to its 1/4-inch progressive scan CCD sensor. It offers a resolution of 704x480 pixels and can capture incredibly detailed images at up to 30 frames per second. With its pan/tilt functionality, the 232D+ can cover a wide field of view, allowing for extensive monitoring areas while maintaining high precision and responsiveness.

In addition to its impressive image quality, the Axis 232D+ features advanced digital zoom capabilities, enabling users to zoom into specific areas without significant loss of detail. The camera is equipped with a powerful infrared capability, allowing it to capture images in low-light conditions effectively. This makes it an ideal choice for 24/7 surveillance in all lighting scenarios.

On the other hand, the Axis 231D+ offers similar high-quality video performance but introduces some distinctive features. It also utilizes a 1/4-inch progressive scan CCD sensor and supports a wide dynamic range (WDR) for improved image quality in challenging lighting conditions. The 231D+ is designed for easy installation and integration into existing systems, making it a versatile option for various surveillance needs.

Both models leverage Axis' digital PTZ technology, providing users with the flexibility to pan, tilt, and zoom remotely via an intuitive web interface. This user-friendly aspect simplifies monitoring and allows quicker responses to incidents when they arise.

Furthermore, both the Axis 232D+ and 231D+ support Power over Ethernet (PoE), eliminating the need for separate power cables and simplifying installation, especially in hard-to-reach locations.

In conclusion, the Axis 232D+ and 231D+ represent Axis Communications’ commitment to delivering high-quality, versatile surveillance solutions that meet the demands of modern security challenges. Their advanced imaging technologies, robust features, and user-friendly design make them noteworthy additions to any security setup. Whether it's for large outdoor areas or indoor environments requiring vigilant monitoring, these cameras provide the performance and reliability critical for comprehensive security.
