Perhaps more importantly, in addition to the added camera cost it will drastically increase storage requirements and costs.Īn increase from 1080p to 4k requires almost four times the amount of storage. This is certainly an option however, depending on the applications, it can be more costly than necessary. Since we said the total number of pixels corresponds to resolution quality, we can safely assume that a 4k camera (with 8 million pixels) has roughly four times better resolution than a 1080p camera (with 2 million pixels) would. In the case of 1080p, it is along the vertical side, whereas for 4k, it is along the horizontal side. = Approximately 8 Megapixels (8 Million Pixels) Total Area.įor now, let’s just keep in mind that the camera name is representative of the number of pixels along either the horizontal or vertical axis of a rectangular image. = Approximately 2 Megapixels (2 Million Pixels) Total Area.ģ840 (Roughly 4k) Horizontal Pixels x 2160 Vertical Pixels It will be easier to illustrate this by showing you the actual full dimensions.ġ920 Horizontal Pixels x 1080 Vertical Pixels The 1080 in 1080p represents the 1080 pixels on the vertical range, whereas 4k represents the (actually 3840) pixels across the horizontal range. However, they are not representative of the same range! To add confusion, both 1080p and 4k are representative of the number of pixels along one of the ranges (horizontal or vertical) of the grid. Knowing this, we can safely assume that the total area ( number of pixels) can be represented by multiplying the height (or vertical range) by the length (or horizontal range) of the image.ġ080p resolution means that the camera’s image will have 1920 horizontal pixels and 1080 vertical pixels, for a total of approximately two million pixels or more commonly stated 2 megapixels. Security cameras generally give a rectangular image of a scene.
