ARCHITECTS' AND ENGINEERS' BID SPECIFICATION

   The network encoder shall be transforming analog video signal into digital JPEG images and transferring into the Ethernet or the Internet for remote monitoring CCTV system. The network encoder shall be a JVC Model VN-A1U or equivalent. The network encoder shall feature a (NTSC/PAL) composite video input and loop through output terminal for existing analog CCTV surveillance system. The network encoder shall produce JPEG compression, picture sizes of 640x480, 320x240 & 160x120. The network encoder shall have programmable IP address that allows install multiple units in the same LAN environment.

   The network encoder shall have a built-in Web Server that allows connect it directly to the Internet without a computer. The network encoder shall feature a FTP server capability for storage of user-designed web pages. The network encoder shall feature NAT/IP Masquerade that multiple VN-A1Us can be connected to a NAT/IP Masquerade compatible router and share a single IP address. The network encoder shall feature a pre/post alarm recording allows record 4 to 16 seconds of images before trigger alarm recording and after ended alarm trigger.

   The network encoder shall feature a motion detection allows indicates any movement in a programmed grid area and detects by sensitivity or minimum area by 8x8 pixels. The network camera shall have user-friendly menu set up and adjustment of compression level, color saturation level, Brightness level, programmable encoder ID, Time & Date and full function control by provided controller & Viewing software and thru Web browser. The network encoder shall incorporate a UDP/IP, TCP/IP, HTTP, FTP, DHCP, IGMP and ARP protocols for various network applications.

   The VN-A1U is fully compatible with VN-C10U, VN-C30U and VN-S400U, which can be easily mixed in a system. The provided controller & viewing software shall feature a recording and playback, snapshot functions allow for PC surveillance system. The network encoder shall feature an external device control by RS-422/RS-232 for another JVC camera and recorder products. The network encoder shall incorporate a 10 Base-T & 100 Base-Tx Ethernet, IEEE802.3 standard communication.

   The maximum length of control data cable (CAT5) shall be 900 feet allows point to point connection and extension can be made thru a switching Hub. Power source shall be DC12V or AC24V. The network encoder's dimensions shall not exceed 1.6”(H) x 7.3(W), x 7.5(D). The unit shall be UL listed.
