The Rocware RC821U is a 1080P Video Conferencing PTZ Camera designed for high-quality video conferencing applications. It features a full-function USB interface, 1080P Full HD resolution, a wide-angle lens with digital zoom, low illumination capabilities, Power over Ethernet (PoE) support, and remote control options.
Function Description:
The RC821U is a PTZ (Pan-Tilt-Zoom) camera that captures video in 1080P resolution at up to 60 frames per second. It is equipped with a 1/2.8-inch CMOS sensor with 2.07 effective megapixels, ensuring high-quality images. The camera supports multiple video output interfaces simultaneously, including HDMI, USB 3.0, and network, making it versatile for various setups. It also offers dual-stream output (YUY2, MJPEG, H.264) to reduce the host codec pressure. The camera's PTZ functionality allows for precise control over its pan, tilt, and zoom movements, which can be managed remotely via RS232, network, or USB. Its low illumination feature, combined with 2D and 3D noise reduction algorithms, ensures clear images even in challenging lighting conditions, with a high signal-to-noise ratio (SNR) of 55dB. PoE support simplifies installation by allowing power, control, video, and audio to be transmitted over a single network cable.
