Complementary devices like remote camera pan/tilt/zoom controls for security installations are also among Visianary Solutions' offerings.
The AVN200 is built on an embedded Linux operating system and encodes video into MPEG-2 at full 720x480 resolution, as well as half D1 (352x480), 480x480, or SIF (352x240) over a range of bit rates from 1.2Mbps (1.6Mbps with audio) up to 7.5Mbps. Those are DVD bit rates. The product doesn't offer advanced encoding features, such as filters or image processing. Audio is encoded at 256Kbps or 384Kbps, MPEG-1 Layer 2. the default bit rate is 3.8Mbps, but you can set a custom bit rate manually. IP packet data can be encapsulatedas either UDP or RTP, with quality-of-service controls for Packet Shaping (for minimizing latency), Forward Error Correcetion ( for RTP streams only), Burst sizes.
The AVN200 is supports unicast and multicast, including IGMP Snooping to allow creation and authentication of member groups. Password protection restricts access to encoded streams.
Built on an embedded Linux operating system, Visionary Solutions' AVN-200 video network appliance encodes video into MPEG-2 and turns that into packetized IP data.
