NDI Camera

Understanding SDI

SDI technology has been around for many decades. Many PTZ cameras will use SDI. However, many newer models now offer NDI. A serial Digital Interface is a cable that allows users to send uncompressed video over long distances. Although it’s an extremely useful technology that people have used for many years, it may be outdated.

SDI is an old technology that hasn’t changed much over the years. However, SDI-equipped PTZ cameras are still quite impressive. High-quality PTZ cameras can be purchased with excellent zoom and noise-reduction capabilities. The SDI format has a lower quality than the NDI.

SDI is reliable and easy to use. Because they are so easy to use, many businesses still use PTZ cameras with SDI. Although NDI can be set up easily, SDI has some advantages. You can find PTZ cameras that only use SDI for a lower price than those that use NDI.

Understanding NDI

It’s best to spend a few minutes understanding NDI. NDI stands for Network Device Interface. NDI cameras can connect to a local network (LAN) and work with other software applications such as Wirecast, OBS, or similar. NDI lets you get the best quality video possible.

You’ll get amazing results if you use an NDI-compatible PTZOptics camera. It’s easy to send and receive high-quality video via your LAN. Many churches and businesses use NDI cameras to send video to various screens. Many things can be done with NDI cameras.

You can use the PTZOptics PTZ camera for amazing footage. Also, you can send that footage anywhere in your network. It’s possible to control multiple NDI cameras with one Ethernet cable. This allows you to capture audio and video simultaneously. This works well; professionals often use NDI cameras to capture high-quality video.

NDI technology remains relatively new, and not everyone has moved to NDI. SDI technology is an older technology that has been used in cameras for decades. It makes sense that it would be deeply ingrained in the current camera tech. Experts believe that NDI will slowly overtake SDI, and SDI may be gone shortly. It’s easy to convert NDI files into SDI, as both are used regularly.

PTZoptics SDI vs. NDI

It is important to remember that NDI is the more recent format when comparing PTZOptics SDI vs. NDI. You’ll find that cameras with NDI capabilities will be slightly more expensive than those with SDI. The standard 12-x zoom PTZ camera costs $1,759.00, the same as the SDI model. You will need to spend $2,199.00 if you want an NDI model comparable.

Is it worth the extra cost to send better-quality video over a network? It all depends on the purpose of the device. NDI is the better format for live streaming. NDI is the right choice if you are looking for the highest-quality video. The NDI camera is not too expensive, so most people will think it’s worth paying a bit more to have NDI.

SDI footage is easy to use. SDI footage can be converted into NDI and sent across a network. It will likely come down to what you can afford and your expectations regarding video quality when choosing a camera. While purchasing the most recent format might be logical, the cost difference may not make it worthwhile.


To be able to choose the right route, you must be honest about your needs. PTZOptics has amazing cameras, whether you are looking for NDI-compatible or SDI options. No matter which model you choose, you’ll be able to get a camera that’s easy to set up. It all comes down to whether NDI is worth the extra cost over SDI.

It is uncertain if SDI will ever be replaced completely by NDI. You’ll still be able to use your high-quality PTZOptics cameras to their full potential. You can choose the one that best suits your budget and needs.
