A 4K IP camera is a type of network camera that captures video with a resolution of 3840 x 2160 pixels, which is four times the resolution of 1080p Full HD video. This high resolution makes it possible to capture fine details in the video footage, which can be useful in surveillance applications where it's important to identify people, objects or license plates.
4K IP cameras are usually designed for outdoor or indoor surveillance and come in different shapes and sizes, including bullet, dome, and PTZ (pan-tilt-zoom) cameras. They use internet protocol (IP) technology to transmit video and audio over a network, which can be accessed remotely from a computer or mobile device using specialized software or mobile apps.
Some 4K IP cameras also feature advanced functionalities such as motion detection, face detection, and night vision, which enhance their performance in low-light conditions. They may also support other features such as two-way audio, which allows users to communicate with people on the other side of the camera.
Overall, 4K IP cameras provide high-quality video surveillance that can help to improve security and safety in a variety of settings, including homes, businesses, and public spaces. However, they may require a higher bandwidth and storage capacity than lower resolution cameras, which should be taken into account when planning for their deployment.
