AVN200
The AVN200 is a stand alone A/V server that streams real time DVD quality video over LAN or WAN infrastructures. It provides video at 30 fps (frames per second) and full screen resolution of 720h x 480v or at a reduced resolution to
conserve bandwidth. Low latency permits accurate remote PTZ control via built-in RS-232/422 channels in the AVN200. Deploy together with the NCC200 IP based code distributor for seamless integration with traditional CCTV systems.
Use any standards compliant method to view the stream including a PC with VSImageViewer or a TV monitor with an IP Set Top Box. Use the AVN200 for cost effective addition of networked video to existing infrastructure or for newer
IP Video applications.
- Stand-Alone Operation. The AVN200 runs independently of any other server. To view live S-Video or composite video streams and configure the product over the network, all that is needed is an AVN200 encoder and any standards-compliant MPEG-2 decoder (hardware or software). Any of three methods, VSImage Viewer (included software decoder), Console Menus, and a Web Interface, can be used to configure the AVN200. TCP/IP, HTTP, and other Internet-related protocols are supported.
- VSImage Viewer. Three VSImage Viewer software decoder Licenses are included with the AVN200. This multifunction application works in conjunction with the AVN200, enabling live viewing, recording, and extensive AVN200 control and configuration. With username and password control, administrators can select and lock an AVN200’s properties for added security. Peripheral devices such as PTZ (pan, tilt, zoom) cameras can also be controlled.
- Superior Audio/Video Quality. MPEG-2 hardware compression and Visionary Solutions, Inc.’s optimized transmission technology provides a superior video image at full frame rates and resolution. The video stream can be viewed by an unlimited number of licensed clients on a LAN and full frame rate (25 PAL to 30 NTSC) frames per second is assured, provided that Chapter 1: Introduction AVN200 User’s Manual 2 bandwidth is available. Available image resolutions are: 720x480, 480x480, 352x480, and 352x240 NTSC; and 720x576, 480x576, 352x576, and 352x288 PAL. The bit rate is configurable. The audio compression is MPEG-1 Layer 2 audio encoding at either 256 or 384 kbps with a 48 KHz sample rate.
- Event Driven. The AVN200 can respond to external events such as motion and intrusion detection. Possible actions include starting a video stream, activating a local switch closure, or activating external devices over an RS-232 or RS-422 cable.
- External Device Connections. The AVN200 connectors include two digital inputs, one digital output, one serial RS-232 port, one RJ-45 LAN Ethernet port, and one full-duplex RS-422 port. These ports allow the AVN200 to interface with a variety of external devices, such as Pan/Tilt/Zoom (PTZ) devices, doorbells, switches, and alarm relays.
- Audio and Video Inputs. The AVN200 audio and video inputs include one BNC composite video input for connecting a CCTV camera, one S-Video input for connecting S-Video cameras or other video equipment, and one stereo audio input for line level sources.
- Security. Administrators can create and modify accounts for authorized users, as well as allow anonymous viewing.
- Forward Error Correction. The AVN200 has Forward Error Correction (FEC) capability on the outgoing video stream. This feature enables the VSImage software to check for and recover lost packets while continuing to produce smooth output video.
