SLIDESHOW: PTZ Cameras and Capture Devices
Getting reality to video and then on to its intended destination is a complex process, but more is now automatically done behind the scenes leaving operators free to concentrate on creativity. Advances in optics and signal processing allow for easy transfer while keeping manual options open in customizing the content for specific applications. The devices found here represent the current state of the art in PTZ/ capture of sound and video.
If the job is sending audio over IP, Barix has a proven hardware base in the
Instreamer. The device can accept any audio, convert it into G.711, PCM or high-quality MP3 streams and send the stream to up to 32 different destinations across the LAN or over the internet. With its Ethernet and serial ports, the Instreamer provides a simple and quick way to get the signal out. Streaming can be set to send always, send on CTS, send on level, or manually via web interface. Up to 32 BRTP streams at 128kbit/s are supported and the SNMP protocol can be used for monitoring.
