VHD New Generation 4K@60fps PTZ camera
NDI®|HX2
80.8° Ultra-Wide-angle
AI Tracking
Compatible with NDI®|HX2 Protocol
NDI is ideal for broadcasting including broadcast studios, live broadcast, gymnasiums, arenas, churches and lecture halls, thanks to its high SNR and ultra-low latency.
4K@60fps UHD Video
1/2.8-inch UHD CMOS sensor with up to 8.51 megapixels offers 4K (3840x2160) UHD images, downward compatible with 1080P, 720P and other resolutions.
Low Light
The application of 3D noise reduction algorithm greatly reduces image noise. Even under the condition of ultra-low illumination, it still keep the picture clean and clear, and the SNR of image is as high as 55dB.
HDMI 2.0
HDMI 2.0 supported; direct output of uncompressed 4K digital videos is available.
AI Tracking
Embedded NPU hardware uses the deep learning technology to extract the target's characteristics and allow smooth face tracking, no matter where the face is facing. The product is applicable to automatic tracking of speakers in lecture and presentation.
12x Optical Zoom
4K UHD lens with effective resolution of 8 megapixels, 12x optical zoom and FOV angle of up to 80° .
Multiple Interfaces
It supports HDMI 2.0 HD output, and also equipped with 3G-SDI interface, the effective transmission distance up to 150 meters (1080P30). HDMI, 3G-SDI, USB 3.0, LAN can simultaneously output 4 channels of high-definition digital signals.
Smart Exposure
The effects of projectors, TV and other devices on the people can be resolved effectively.
Built-in Gravity Sensor
Automatic image rotation supported for easy installation.
Remote Control
Through the LAN, RS232 and RS485 serial ports, the camera can be controlled remotely.
