What is a 4K Security Camera?

The movement beyond 1080p full HD image resolution has begun. Terms such as 2K Super HD and 4K Ultra HD are now becoming everyday words when people speak of television screens, computer monitors, or mobile phone resolutions. But what do they mean? And what does it have to do with the future of security systems?

Details are incredibly crisp, with sharp definitive lines that distinctly outline every object and feature.

Digital Zoom

The higher amount of pixels allows for a higher quality digital zoom so that details stay legible for longer as the zoom is applied.

Color Night Vision

Larger image sensors capture more light, which improves the color and contrast in low-light settings.

Image Sensors

A major determining factor in video quality is the size of the camera's image sensor. These sensors are classified by their number of megapixels (the equivalent to one million pixels). Ultimately, the higher the amount of megapixels, the better the video resolution.
