What is the resolution of 4K PTZ camera?

If you’ve researched PTZ cameras, you’ve undoubtedly come across the term 4K PTZ. A 4K PTZ camera is an ultra-high-definition camera that offers both cinema production and streaming in 4K.

We’re going to answer a lot of questions in this article, including:

  • What’s 4K resolution?
  • What does a 4K camera mean?

Basic Viewing Requirements

Your camera may be able to shoot in 4K, but that doesn’t mean that every viewer will be able to watch your content in this resolution. Viewing requires one of a few things:

  • 10 Mbps – 25 Mbps if streaming
  • supported television or screen

The consumer’s device must have a video resolution of 3840 x 2160 pixels or higher. Color depth must be at least 10-bit, and a high dynamic range must be present. Black and brightness levels must offer 1,000 nits or higher for brightness and 0.05 nits or lower for black.

4K Resolution Standards

Due to the high bandwidth requirements of 4K resolution, multiple codecs have been created to handle the video format. A few of the most common standards and solutions include:

  • H.265, which is a high-end compression standard that is being used with video up to 8K;
  • VP9, which Google developed, is designed for streaming usage and offers up to a 50% reduction in bandwidth requirements.

Of course, lower resolutions can be scaled up to fit on these larger resolution screens. However, the scaling does not bring the quality of the video up to the high resolution captured with a 4K PTZ camera.

A 4K PTZ camera can capture better quality images and video. Higher resolutions are necessary for some industries, such as sports and medicine. However, with the adaption of 4K technology, there’s a growing demand from consumers to produce 4K quality.

What 4K Content is Available?

  • streaming sites, such as Netflix and YouTube;
  • DVD and movies;
  • television shows;
  • professional settings.

Broadcast television has many channels in 4K, and as more devices offer this resolution, the content will continue to be produced in 4K at higher volumes.

Key Definitions to Know When Choosing PTZ Cameras

What Does 4K UHD Mean?

  • Ultra-high-definition, or UHD, is a term that you’ll see added after the word 4K. A basic way to understand the two is that:
  • 4K is what the production team sees and what’s seen in cinema
    UHD is what the consumer will see.

UHD is a step up from standard HD and is often associated with an aspect ratio of 1.78:1.

What Does 4K Resolution Mean?

A basic 4K resolution definition is four times higher than 1080p high-definition. However, the base 4K is less “powerful” than 4K UHD, with better resolution and overall picture quality.

In terms of resolution, 4K is considered a resolution of 3840 x 2160 pixels. This is where the 2160p meaning comes from.

If you’re looking for a 4K PTZ camera, the above information will help you determine the camera’s resolution and shooting ability. A 4K camera will offer a clear, crisp resolution that empowers viewers to watch videos like never before.
