The AXIS 292 Network Video Decoder can convert one stream of MPEG-2 or Motion JPEG video and audio from an Axis network video product into analog signals. This allows analog video devices such as regular TV sets, analog monitors and existing analog video switches to be connected to an Axis IP-based video system.

Via an Ethernet network such as a LAN or corporate network, the AXIS 292 takes a stream of digital video and audio from a specified Axis network camera or video server, and converts it in real-time into high quality, analog signals.

When used in combination with Axis video servers (such as the AXIS 250S MPEG-2), AXIS 292 decoders can quickly and cost-effectively connect two analog systems at different locations via a LAN/MAN/WAN Ethernet network. Users would be able to use existing video matrices and other analog technology to receive video and audio from distant analog cameras or systems as though they were placed locally with the operator even though they might be located in a different city. See schematic below.

The AXIS 292 is ideal for retail applications, campus security and city center surveillance.

Features:

• Decodes network video and audio without the need of a PC     
• Provides one channel of video and simplex audio     
• Supports both composite and Y/C (S-VHS) video     
• Supports all MPEG-2 and Motion JPEG based Axis products; 
  AXIS 292 can automatically detect the format used     
• Supports both PAL and NTSC video standards     
• Capable of decoding video at full frame rate (30/25 fps)     
• Built-in Web server for administration     
• Analog video resolution of more than 500 TV lines (depending on the quality of the video source) 

Application possibilities:

The AXIS 292 Network Video Decoder is primarily used as an extension to existing installations.

• Decoding of a single analog video in a network video system - A digital surveillance system with a network video decoder can display network video on a public display TV or other analog monitors, i.e. in a retail shop. See system overview, below.   
• Connecting two analog systems over a LAN/WAN - Organizations that operate in multiple buildings can reduce the cost for security by integrating a remote analog system with another analog system at the main location. See schematic.   
• City surveillance systems - Most city centers, which have a good networking infrastructure, can easily expand the existing analog system by cost-effectively connecting devices through a wide area network with the use of Axis network cameras or video servers and AXIS 292 Network Video Decoders. Existing analog cameras with features such as day/night functionality can still be utilized in such a system. See schematic.

System overview

Diagram explanation:

1. Digital video and/or audio is generated in an Axis video server or network camera     
2. Digital video and/or audio is sent over an Ethernet network (e.g. LAN/MAN/WAN/Internet)     
3. A PC with software applications may use the digital video/audio for recording and alarm management without affecting the operation of the decoder     
4. Digital video and/or audio is decoded and made available to analog devices such as monitors, TV sets and analog video switching devices.

What you need:

• An Axis MPEG-2 or Motion JPEG-based video server or network camera     
• An analog composite or Y/C (S-VHS) video monitor or other device with analog input     
• Coax cable     
• Regular straight Ethernet cable     
• Available port on your hub or router 

Schematic: Connecting separate analog systems via an Ethernet network

The following diagram shows how a distant analog monitoring system (pictured in the bottom half of the diagram) can gain access to any analog cameras in a separate analog system (illustrated in the first half of the diagram) via an Ethernet network. In this example, two analog cameras (7 and 8) have been selected for viewing both locally as well as remotely.

When AXIS 292 Network Video Decoders are used in combination with Axis video servers (such as the AXIS 250S MPEG-2), the decoders can quickly and cost-effectively connect two analog systems at different locations via a LAN/MAN/WAN Ethernet network. Users would be able to use existing video matrices and other analog technology to receive video and audio from distant analog cameras or systems as though they were placed locally with the operator even though they might be located in a different city.
