12AXIS 231D+/232D+ - Video Streams

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.

How to stream MPEG-4

Deciding the combination of protocols and methods to use depends on your viewing requirements, and on the properties of your network. The available options in AMC are:

Unicast RTP

This unicast method (RTP over UDP) should be your first

RTP over RTSP

This unicast method (RTP tunneled over RTSP) is useful

RTSP traffic.

 

 

 

 

 

RTP over RTSP over HTTP

This unicast method can be used to traverse firewalls.

 

 

Firewalls are commonly configured to allow the HTTP

 

 

protocol, thus allowing RTP to be tunneled.

 

 

 

 

Multicast RTP

This method (RTP over UDP) should be used for live multicast video. The video stream is always

 

up-to-date, even if some images are dropped.

 

 

Multicasting provides the most efficient usage of bandwidth when there are large numbers of cli-

 

ents viewing simultaneously. A multicast broadcast cannot however, pass a network router unless

 

the router is configured to allow this. It is not possible to multicast over the Internet, for example.

 

Note also that all multicast viewers count as one unicast viewer in the maximum total of 10

 

simultaneous connections.

 

 

 

 

AMC negotiates with the camera to determine the transport protocol to use in the order listed above. This order can be changed and the options disabled, to suit specific requirements.

231D+, 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.
