The JVC VN-E4 is a 4 port video encoder which allows up to 4 analogue CCTV cameras to be broadcast over IP-based networks such as a Local Area Network or the Internet.

Using a video encoder allows live images to be digitized for broadcast over digital networks allowing you to take advantage of digital IP camera benefits such as remote access or video motion detection with pre-/post-recording.

The JVC VN-E4 also includes two-way audio capability allowing you to not only hear sounds from the video encoders location but also communicate with people near the device. Like all video encoders offered by Network Webcams, the JVC VN-E4 4-port video encoder has a built-in web server and can be viewed over a Local Area Network (LAN), Wide Area Network (WAN) or via the Internet.

JVC VN-E4 - Key benefits:

Digital IP-based benefits from existing analogue CCTV camera technology. Without compromising on your initial CCTV investment you can add this device to add digital IP-based benefits to up to 4 existing analogue CCTV cameras

JVC VN-E4 - Key features:

Connection for up to 4 analogue CCTV cameras (composite BNC connection)
30fps at VGA (640x480 resolution) offering up to 120fps in total
Multi-streaming encoding for simultaneous VGA and QVGA video on four channels
Video mode high quality JPEG with multi-cast support
Motion detection feature with pre-/post-buffer recording
Alarm recording using an external alarm input such as a infrared sensor, window/door sensor or door bell
Two-way audio allows you to listen-in on sounds near the encoder (microphone required, not supplied) or communicate directly with people near the encoder (speakers required, not supplied)
Support for JVC and Pelco-D control and PTZ protocols using auxiliary RS-485 or RS-232C ports
FTP client function for image storage based on alarm activity

JVC VN-E4 - Typical applications:

Integrate into an existing analogue CCTV system to provide IP-based functionality such as remote access to your cameras from any location on the Internet, image transfer to an FTP server based on alarm activity from external sensor input or by video motion detection etc. Suitable for small-medium sized businesses in retail, education, manufacturing environments etc.
