Hikvision Digital Technology Co., Ltd., a surveillance-product supplier with headquarters in China, launched DS-42xxHCI/HFVI series audio/video compression card. It adopts high-performance video processing chip, standard H.264 video codec, and real-time audio/video capturing and encoding.
Some of the major requirements for compression cards in the industry are stability, flexibility, and the ease of development and customization. By adopting a high-performance processing chip that can support up to 8-ch 4CIF real-time encoding, the series audio/video compression card requires fewer chips on the board resulting in extra-low power consumption and higher stability. A full SDK and demo source code is also available, which provides a platform for development and customization. Besides, the on-board video/audio input pins allow users to build a PC-based DVR system with their physical video/audio input interfaces; its termination jumper design on each 75 Ohm matching resistor also enables the video loop out function as an option.
The series compression card delivers up to 16ch 4CIF real-time encoding and 16ch CIFencoding on dual stream mode, which enables the product to record in high quality and full frame rate, and at the same time to cover the requirement on narrow band transmission and cell phone surveillance applications. The product also features 25fps (PAL) / 30fps (NTSC) and supports variable bit rate and frame rate, motion detection, OSD auto switch, LOGO and MASK overlay.
The series audio/video compression card is compatible with the main-stream CPU, motherboard, and display adapter, providing a huge convenience for users while building up a PC-based DVR system.
