In the world of video production and broadcasting, several terms are often used to describe different versions and variations of a technology called NDI (Network Device Interface), which is developed by NewTek. Here's an overview of the differences between IP, NDI, NDI|HX, NDI|HX2, and NDI|HX3:

IP:

IP stands for Internet Protocol and is a generic term used to describe the transmission of data  packets over a network, such as the internet or a local area network (LAN). In the context of video production, IP refers to the use of network infrastructure to transport video, audio, and other media data.

NDI:

NDI, or Network Device Interface, is a high-quality, low-latency video over IP protocol developed by NewTek. It allows video sources and destinations to be connected over a network, enabling the transmission of live video between different devices and software applications in real-time. NDI uses existing Ethernet networks and does not require specialized hardware.

NDI|HX:

NDI|HX (NDI|HX1) is a variation of NDI that offers higher compression to allow for efficient video transmission over wireless networks. It is specifically designed for use with mobile devices, cameras, and other wireless video sources. NDI|HX enables wireless camera feeds and streams over Wi-Fi networks while maintaining relatively low latency and maintaining visual quality

NDI|HX2:

NDI|HX2 is an updated version of NDI|HX that provides improved video quality and performance over wireless networks. It uses better compression algorithms to reduce bandwidth requirements while maintaining low latency and high-quality video transmission. NDI|HX2 is often used in wireless camera systems and other applications where real-time, high-quality video over wireless networks is essential.

NDI|HX3:

NDI|HX3 is the latest iteration of the NDI|HX technology. It offers further enhancements in video quality, performance, and compression efficiency compared to its predecessors. NDI|HX3 is designed to deliver high-quality video over wireless networks, providing near-zero latency and visually lossless transmission. It is used in a wide range of applications, including live production, streaming, and remote collaboration.

It's worth noting that the differences between these variations of NDI lie primarily in terms of their capabilities, video quality, and performance characteristics. Each version aims to optimize video transmission for specific use cases, such as wireless streaming or mobile production.

WINSAFE 12G-SDIwith big 4/3” inch lens 4K 30X/20X PTZ Video Camera all will support NDI|HX3 to offer more clear image and low latency video transmission are good used on the professional broadcasting live steaming scenarios.

Normal 4K60fps 30X/20X PVC-G530/520, UHV-450H etc. 4K 30X/20X PTZ Video Camera also support NDI|HX3, it can good used in the Sports living broadcasting, church broadcasting etc.

Other normal IP PTZ Camera also can support IP and NDI|HX to meet the diffeerent  customer needs.
