 Equipped with one BNC video connector for connection of an analog and a loop-through video output for connection to an analog monitor, the VN-A1U can be connected directly to an Ethernet network for delivery live video images. It is not only the simplest way to convert your existing analog CCTV surveillance system into a flexible computer-controlled remote monitoring system, but it also allows you to use analog cameras and V.NETWORKS cameras in the same system.
With the VN-A1U, camera monitoring is never restricted to a dedicated system or monitor. Multicasting 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-A1U is accessed by multiple clients and network traffic management is easy and efficient.
 
The VN-A1U features a built-in web server that allows you to connect your surveillance system directly to the Internet without having to route it through a dedicated web server. This allows you to deliver high-quality, real-time images to any Internet-connected computer in the world, giving you unlimited flexibility. Images can be monitored through a standard web browser and various camera functions can all be controlled.
 Built-in alarm in/out terminals allow you to connect an infrared sensor or door alarm to automatically trigger alarm recording. A 2MB memory is available for pre/post alarm image storage. When you use a removable Compact Flash memory card (up to 512MB)*, you can store multiple pre/post alarm images.
*Note:
For compatible CF cards, the following manufacturer's products have been confirmed: SanDisk Corporation, ADTEC Co., Ltd., Hagiware Sys-Com Co., Ltd., Lexer Media, Inc.
 Add an extra layer of security to your system with this convenient function. The 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. The minimum area size is 8 x 8 pixels.
The VN-A1U comes with exclusive browser software that not only allows you to view camera images on a PC, but also lets you adjust various camera settings and picture quality. The latest updates can be downloaded from JVC's website.
The VN-A1U is equipped with a switchable RS-422/RS-232C port and an exclusive RS-422 port to control external devices. Using the VN-SE400U external device control package in combination with VN-S400U and VN-SV400U browser software, this convenient capability makes it possible for you to control operations and settings on JVC analog cameras, all through a single window on your PC screen.
