Features

 1080P HD Resolution:

Applies SONY 1/2.8” Progressive CMOS sensor, 2.07 Megapixels, max.1920x1080 high resolution with frame rate up to 60fps.

  Abundant OutputsHDMI+3G-SDI+LAN+USB3.0

Supports HDMI, 3G-SDI, LAN, USB3.0 HD 1080P output in sync.

  Ultra High Frame Rate:

Video output frame rate can reach 1080P 60fps. IP supports POE(optional) and NDI®|HX2(optional) for more functions and applications.

  12x 20x Optical Zoom Can be Optional:

HD91R: 12x optical zoom+16x digital zoom.

HD91A: 20x optical zoom+16x digital zoom.

  Low Light:

Brand new CMOS image sensor with ultra high S/N Ratio can effectively reduce image noise in low light conditions. Applied 2D&3D Digital noise reduction at the same time, it reduces image noise greatly, even in ultra low light conditions, it could still remain the frame clean and clear, S/N Ratio of the image is higher than 55dB.

Remote Control:

Use RS232, RS422/RS485 serial ports to control multiple cameras with daisy chain.

  Signal Transparent Transmission Function of Infrared Remote Controller:

Apart from receiving its own infrared remote controller’s signals, it can also receive signals from the user’s infrared remote controller and send to video conference terminal via VISCA IN port.

Various Video Compression Standards:

Different interfaces support YUY2, H.265, MJPG, H.264 multiple video compression formats.
  Various Network Protocols:

Supports ONVIF, SRT, RTSP, RTMP, RTMPS, NDI®|HX2 (optional) and other network protocols.
  Multiple Control Protocols:

Supports VISCA (including VISCA Over IP), PELCO P/D, NDI® (optional) protocols, and automatically identifies protocols.

  Multi-installation Methods:

Wall mounting, desktop or ceiling mounting.

New generation AI human tracking algorithm:

Upgraded to support AI intelligent tracking and automatic framing functions.
