1. Features and Benefits
The video decoder is a high resolution, Ethernet ready digital video product. Via an Ethernet network
such as LAN or WAN, the video decoder takes a H.264 stream from our IP camera or video server, and
converts it in real-time with high quality analog video signals. This allows analog video devices such as
TV system, analog monitors or existing analog video switches to be connected to our IP-base
surveillance video system.
● Up to D1 H.264 video decoding
The video decoder can convert network H.264 stream into analog video signals. It also can
automatically detect remote stream format, resolution and video standards. It can decode video at
full frame rate(30/25 fps).
● Supports both BNC and VGA video output
The video decoder has 1 BNC and 1 VGA interface. This feature allows analog video devices such as
LCD TV sets and analog monitors to be connected to our IP surveillance video system.
● Digital Time Code Embedded
The “Digital Time Code Embedded” function is to embed the recording time in the H.264 bit stream.
Therefore, each image frame has its respective time when it was recorded. It is very useful when
users want to find the video at an exact time or between a certain time intervals.
● Powerful Surveillance Software
To extend the capabilities of the video server, a powerful surveillance program is included in the
package and is totally free to use. Users can easily utilize the existing PC to be a digital video
recorder. Schedule recording, alarm recording and manual recording keep every important image
recorded in the local disk. Reliable and accurate motion detection with instant warning makes you
responsive in every condition. Quick and simple search and playback function lets you easily find
the images you want.
