8CH HD-SDI ข้อมูล /IP, วิดีโอดิจิตอลผ่านไฟเบอร์

Brief
VHD300 series provides various functions for customers with innovative design. It provides a wide range of services covering video, audio, RS232, RS422/485, contact closure, phone, Aiphone, 10/100M Ethernet, B code, explosion-proof hotline, and E1 with the capacity of up to 16 point-to-point HD-SDI transmission on one single fiber.
With patented design, VHD300 series can support various functions while greatly reducing the volume for easier installation. The stand-alone module can be plugged into the 4U 19'' chassis with redundant power or the 4U 19'' passive chassis.
VAD aims to produce international boutique and focus on providing high-quality products and service. The brand new VHD300 series inherited and developed VAD's faith. Its superb quality and high durability serve for image monitoring system which has higher requirements. Its original dust cooling structure provides greater environmental adaptability.

Note:
Stand-alone by default. Suffix "-U" means rack-mount which needs a 19'' 4U backend receive chassis.
D: Optional bi-direction data; A: Bi-direction audio; Suffix "-IP": 10/100M Ethernet channel.
The data channels can be customized to the combination of audio, RS232, RS422/485, contact closure, phone, aiphone, Ethernet, B code, or explosion-proof hotline, E1, etc...For example, 2D+2A+4C. Please inquiry us the model.
The default transmission distance is 0- 20km. The maximum distance is 60km. 40/60/80/100Km for optional. Note: The distance is based on the link-loss less than 0.4dB/Km@ 1310nm, 0.25dB/Km@1550nm.
