The Avigilon H.264 analog video encoder with 4 audio inputs and 4 audio outputs is designed to integrate legacy analog cameras into a High Definition IP surveillance system. It transmits images over 100BASE TX using H.264 technology to achieve the lowest network bandwidth, and requires minimal storage for video at high frame rates with superior image quality. The encoder supports NTSC and PAL video standards. It also uses an industry-leading motion adaptive 3D deinterlacing algorithm to produce sharper and more accurate video that is free from interlacing artifacts. The encoder includes an RS- 485 interface for PTZ support and an external I/O interface for connecting alarms and relays.
