Full HD vs. 4K: Advantages for surveillance and conference cameras?

4K cameras offer higher resolution than Full HD cameras. However, lower resolution also has its advantages:

Image quality: If the sensor sizes are the same, a Full HD sensor has larger pixels, allowing each pixel to capture more color and contrast information through the same lens. This results in better colors, sharper images, enhanced clarity, and improved contrast across the frame. If the resulting image will only be viewed on a Full HD screen, the image from a 4K camera may appear worse in quality.

Bandwidth and processing requirements: Higher resolution video requires more bandwidth for transmission, especially important for IP streaming, and demands more processing power for encoding and decoding. By using a Full HD camera, you can reduce the strain on your network and processing resources, making it more manageable to handle and distribute the video content.

File size and storage: Higher resolution video files are larger in size, requiring more storage space. Opting for a Full HD camera allows you to save storage costs and reduce the amount of storage infrastructure needed to manage your video recordings.

Makeup and appearance: Higher resolution cameras tend to capture more detail, including imperfections and blemishes. With a Full HD camera, these details are less pronounced, reducing the need for heavy makeup or meticulous grooming. It saves time and effort for subjects or presenters who may not require intricate touch-ups for their appearance.

Background distractions: A higher-resolution camera captures more details in the background, potentially revealing unwanted objects, clutter, or distractions. With a Full HD camera, these details are less prominent, making it easier to create a clean and visually appealing background.

These advantages of a Full HD camera should be considered when weighing the benefits of resolution and the specific requirements of your use case.
