JVC VN-E4U Video Server (Encoder) produces 30 fps at VGA (640 x 480) per Channel Capable of encoding at a maximum frame rate of 30 fps at VGA (640 x 480) per Channel, the JVC VN-E4U offers 120 fps in total. Normally, when the number of channels increases the frame rate tends to drop, however the VN-E4 will ensure “VGA 30fps” for each channel. This produces a smooth and natural pictures without degradation.
  The JVC VN-E4U is capable of streaming VGA and QVGA simultaneously. This Multi-streaming Encoding feature comes in very handy when some clients have limited bandwidth while other clients have enough bandwidth.
  Pre/Post Alarm Recording and Motion Detection Function adds extra layers of security. Built-in alarm in/out terminals allow you to connect an infrared sensor or door alarm to automatically trigger an alarm recording. A 2MB memory is available for pre/post alarm image storage, and via FTP it is able to send the alarm image to specified server. Motion detection function automatically indicates if any movement occurs in a specified area of the screen. You can specify the detection area and select the sensitivity level.
  Support for JVC and Pelco-D Protocol The JVC VN-E4U is equipped with two ports, RS-485 or RS-232C, to control external cameras. Using the external device controller in combination with built-in viewer, this convenient capability makes it possible to control operations and settings on cameras supporting JVC and Pelco-D* protocol, all through a single window on your PC screen.
  Increase your surveillance twofold with two-way audio capability. The VN-E4 video Server offers audio input and output terminals so it not only can monitor audio but also emit a sound to startle and discourage intruders.
  Multicast Capability With the JVC VN-E4 Encoder, camera monitoring is never restricted to a dedicated system or monitor. Multicast capability allows this versatile video server to deliver the same high-quality images to any and all computers on your network. There’s virtually no frame rate degradation when the VN-E4 is accessed by multiple clients. Network traffic management becomes easy and efficient.
