It’s not easy to choose a high definition camera. After all, there’s a lot that you need to consider before investing in one. Often, readers are confused between HD-SDI and analog cameras. This blog post will help readers understand how the two cameras work and which is better suited.


Analog cameras

Analog cameras are old style cameras that we often see in CCVT systems on streets and in workplaces. They are hard-wired and difficult to install.


To install analog cameras, you’ll have to run a coax cable all the way to a digital video recorder from the camera. Although these cameras might be available at cheap rates, if you consider the overall installation cost, they aren’t cost-effective solutions.


Despite these issues, analog cameras can be suitable for monitoring some areas. However, keep in mind that these cameras don’t offer great image quality, and hence, aren’t the best at capturing details.

In contrast with analog cameras, High Definition Serial Digital Interface cameras (HD-SDIs) are technologically advanced and uniquely designed camera solutions used for a wide range of purposes. They are capable of transmitting an uncompressed video over coaxial cable and can easily support 720P and 1080P resolution. This means that these cameras not only provide you with premium quality image but also record high-resolution footage.


Here are a few advantages of HD-SDI cameras that make them a much better option compared to their alternatives.


  • Non-Return to Zero Inverted encodings

  • High-quality video footage regardless of weather and light conditions

  • Excellent zero recovery

  • Lower latency for digital zooming

  • Ideal for long-range applications.

HD-SDI cameras are relatively a little expensive, but easy to install and maintain. From military to aviation, these cameras are used in many different industries. Their anti-vibration mechanism makes them a perfect solution for aircrafts too. Considering these benefits of HD-SDI cameras, they’re certainly a better option than analog cameras.
