Of network speed dome future technology trends (1)

Preface

High speed dome camera is a high end ball camera with running fast, precise, flexible monitoring mode and other features, has been widely used in green city, campus monitoring, unmanned substation, etc.

Speed dome has become more and more well-known. With high speed dome camera market promotion, application begins rendering a pluralistic development. Due to high definition technology, intelligent, networked, and other technologies to make a speed dome features abound.

Network high speed dome camera is a high speed dome camera with important branch, is the simulation speed dome and IP technology integration development of perfect crystal.

At the high-speed ball, as long as you can to increase a IP modules constitute a basic network speed dome. Structurally, network intelligence high-speed ball at least simply leads to the power cord and a network cable, and its wiring easier. In transport mode, network intelligence high-speed ball to spread through the network, the spread of digital signals, the transmission range is wide, easy to implement remote access.

Future technology trends

-Definition of

As the international market and domestic market for monitoring system of universal access to and use of the increasingly high demands of an image: from the very beginning to see the image, the image you want to clear, to the future can be processed analysis of high-definition images.

The entire market-definition of atmosphere, consumer demand will undoubtedly stimulate the HD megapixel network camera, HD technology and products quickly.

Traditional network ball based primarily on CIF and D1 resolution of video processing and video visual range is small, the resolution is insufficient to see image detail.

High definition network ball first solved "see clearly" challenges, up to 1920 × 1080 resolution is the video detail glance; 16: 9 video format that also solves the "see wide" challenges, relative to the traditional 4: 3 video, high definition network coding directly improves the Visual width 30%, more suitable for security monitoring applications. In particular, the following places, high definition network render sphere can:

1, large indoor monitoring

Great for similar courts, Guild Hall, library, etc. larger range of indoor applications, high-definition of picture quality and wide Visual angle and features will be of benefit to the security system of monitoring.

High definition network ball even monitors to specific characteristics of an article, thus protecting the venue's security.

2, pavement, crimp monitoring

Spacious pavement and bayonet is often the challenges of traditional monitoring.

To a common intersection, for example, often require 3-4 camera using can override, and because of the lack of clarity of the image, in order to see an object often need to stretch on the lens, and require frequent rotation. High definition network ball, can provide almost 6 times the visible range of the traditional monitoring and analytical skills, be able to see images of arbitrary local details, generally without the need of the lens. And wider Visual width guarantees 1-2 cameras to cover the entire intersection, reduces the burden on the monitor.

Similarly for high-speed card port, road, etc. larger scene monitoring environment, high-definition networks ball provides administrators a great convenience and effective monitoring quality.

3, power system

Apply to power plants, substations, outdoor, Tower, high-risk areas, such as electric power system and video surveillance.

4, intelligent analysis

High resolution, high definition images for intelligent analysis provides unmatched image sources, improving the accuracy of the late video analysis and reliability.

High definition network ball as a high-performance coding device, in the main application features generally shown in Figure 1, based on the four modules: video module, the audio module, coding, network modules.

Video module:

Video module is mainly responsible for the acquisition of HD integration camera HD-SDI/SDI signal, and reconstruction and decoding will be single serial HD-SDI/SDI signal decoding into YCbCr data sent to the encoding module, data flow shown in Figure 1-2.

If the camera directly output YCbCr data then this module can be omitted.

Audio module:

Audio module is composed by the encoding and decoding.

Front-end acquisition analog audio signals, including linear input and a microphone input, and decoded into IIS data sent to the code module. Decoding section coding module complete IIS data encode the voice signal is amplified by a source output.

Encoding module:

Encoding module is mainly responsible for video and audio encoding and decoding.

Support for H.264 video codec, MJPEG encoding format, resolution maximum support 1920 × 1080 available in real time, Main and High profiles of H.264 encoding Baseline. Audio codec support for AAC, MP3, G.711, mainstream formats.

Network modules:

Network part compatible 10M and 100 m Ethernet, responsible for audio and video data sent to the server, storage, support RTSP, standard network protocols, web operations.
