Do You Have 4K Video Ultra HD
4K Ultra HD/HD/megapixel technology enables network cameras to provide higher resolution of video images than analog CCTV, i.e. the ability to see more details or have a wider coverage – a key consideration in video surveillance applications. With an HDTV or megapixel network camera, the resolution is at least three times better than an analog CCTV camera. 4K Ultra HD offers four times the resolution of HDTV 1080p.
Combining HD/megapixel network cameras with a selection of non-megapixel network cameras that are optimized for other needs (such as powerful optical zoom, extreme light sensitivity or low cost) creates video surveillance installations that are effective, reliable and cost-efficient.
HD/megapixel surveillance
HD and megapixel network cameras have an important role to play in video surveillance applications. They can provide images that are more useful, with more image detail and with wider coverage than standard resolution cameras. Depending on your requirements, Axis network cameras can bring the advantages of HD, megapixel and network technology to your surveillance application.

The variation of requirements within video surveillance is enormous. However, it can be boiled down to a choice between two different priorities.
HD/Megapixel solutions
In this case, the aim is to obtain a general overview of a scene. In a shopping mall, for instance, your primary goal of a camera installation may be to watch for the presence of people and view their movements—not the identification of individuals. Or you may want to see whether a parking lot is full or has empty spaces, rather than identify individual cars or read license plates. For overview applications, sufficient resolution and coverage of a scene may be achieved with a single HD/megapixel network camera or a number of non-megapixel network cameras.
