IDM-VNT2204

1. Overview
The IDM-VNT2204 Multi-Service Video Optical Terminal adopts advanced all-digital uncompressed video transmission technology for high-quality video transmission. It transmits two channels of one-way SD video (or one channel of two-way video) over fiber optic lines, with two groups each sharing 100M wire-speed Ethernet bandwidth (200M total Ethernet bandwidth on the fiber), meeting the requirements of certain departments for transmitting two groups of physically isolated 100M Ethernet bandwidth. It also provides 4 voice interfaces (telephone or EM 2/4-wire audio) and 2 RS232/RS485 interfaces. It supports high-quality transmission of any high-resolution static and dynamic images. The IDM-VNT2204 Multi-Service Video Optical Terminal is a highly reliable, cost-effective, high-transmission-quality long-distance video transmission system. It is suitable for fiber-optic CCTV network systems, traffic surveillance, industrial surveillance, building surveillance, video conferencing, high-quality video conferencing, distance learning systems, and more.

3. Application Example 1

Point-to-point application: via direct fiber optic connection, bidirectional transmission of video, voice, and control signals can be achieved. The remote PTZ (pan-tilt-zoom) camera can be controlled via a control panel or joystick, with support for video and voice binding.

4. Application Example 2

The IDM VNT2204 can interoperate with our company's centralized multi-service transmission device, the IDM MSAP-CP, using the VNE card, to form a point-to-multipoint star network where multiple remote video and voice signals are centrally accessed at the control center. The control center can display multi-screen video on a large display, and the dispatch console can control the remote PTZ cameras via keyboard or joystick, with support for video and voice binding. The IDM MSAP-CP connects to PCM equipment via E1 interfaces or directly outputs 64K services to achieve remote voice access.
