SDI VS IP VS NDI, Which is more better?

October 14,2022.

What is SDI PTZ Camera?

SDI— Serial Digital Interface—was first standardized by SMPTE in 1989, marking a revolutionary transition from analog to digital video infrastructure. Which is the standard for video transmission to uncompressed, unencrypted digital video streaming over coaxial cable, with speed that are based on a 270Mbps transfer rate over a single coaxial cable.


WINSAFE SDI Camera like AMC-S3003 & AC3-S3003 30X SDI PTZ Broadcast and Conference Video Camera are used for more production systems which can be recorded or for a live broadcast show.

AMC IP+SDI Recording PTZ Cameras


SDI cables can transmit uncompressed video over long distances, can connect to cameras, television, video switches, encoders, production systems, and more. They’ re helpful situations where you cabling may need to be 50-feet or longer.


Pros of SDI Cameras

  • Can send uncompressed video over long distances
  • Compatible with most video sources
  • Broadcast quality video


Cons of SDI Cameras

  • Video is uncmmpressed
  • Camera can’t be controlled via SDI cables




However, the need for increased bandwidth for the transmission of ultra high definition(UHD) content and better connectivity, combined with the growing over-the-top(OTT) market, simply outweigh the capabilities of what SDI can offer. Due to this, there’s been a shift to internet protocol(IP)-based networks for all-IP studio operations.




What is IP PTZ Camera?

IP networks untilize internet technology ecosystems that offer more agility and flexibility for broadcasters. In the long run, this means decreased costs, improved bandwidth consumption at higher bit rates, and improved overall efficiency. Additionally, IP switches are bidirectional can can manage multiple input and output ports, unlike SDI.



WINSAFE IP Version PTZ Camera contain 35X, 20X, 10X Version, AMC-320/321/310 are the all video interface(Contain SDI, HDMI, IP, USB2.0 interface) with cost-effective price for the normal conference, living steaming, telemedicine etc. application. High middle level we have  UHV-12X/20X/30X-IP-S Series PTZ Video Camera can suitable for different customer.


Anyway normal IP PTZ Camera are easy connect and easy set up etc., but if your internet is not good, it will have the delay and the video maybe loss. So the NDI is coming, it can solve more of normal IP PTZ Camera problems.





What is NDI PTZ Camera?

An NDI camera communicates via the Network Device Interface(NDI) protocol. Therefore, they can integrate with software apps and connect to your LAN.


NDI is a video-over-IP standard created by NewTek that makes it easier to transmit high-definition video for live video or live steaming productions. The two-way communication that NDI offers allows NDI PTZ Cameras to cotrolled using one Ethernet cable. In addition, that single cable can transmit audio and video. To top it all of that camera can be completely powered by that same Ethernet cable. Allowing you to just run a single cable!


Additionally, NDI has an auto-discovery feature that makes it easy to manage video sources on your network. For example, PowrPoint Slides or hymn lyrics can be sent from one device to another used for live steaming via NDI.


Pros of NDI Cameras

  • Easy to set up
  • Use advanced video compression to send and receive high-definition video
  • Broadcast quality video



Cons of SDI Cameras

  • Video is uncmmpressed
  • Camera can’t be controlled via SDI cables



Pros of NDI Cameras

  • Easy to set up
  • Use advanced video compression to send and receive high-definition video
  • Auto-discovery feature allows for easy management of video sources
  • Low latency audio and video
  • Can be powered by same Ethernet Cable
  • Can be controlled via same cable



Cons of NDI Cameras

  • Video cmpression



Many steamers prefer NDI because the technology is newer, it compresses the video for better steaming quality with lower latency.


WINSAFE Full NDI PTZ Camera, contain 30X, 20X, 12X, also have the NDI HX PTZ Camera, contain 35X, 30X, 20X 12X and 4K, 1080P can be choosed bu you in different need.


Conclusion

The SDI stand is traditional broadcasting customer choose, it can cmpatatible with most video sources and send uncompressed video over long distance. Normal IP PTZ Video Camera with all interface are more popular now, is the main market product. But 4K and low latency, NDI PTZ Video camera will be future broadcasting and living steaming main product. Any series PTZ Video Camera you use, welcome to contact WINSAFE, we will offer the suitable solution to you.
