What’s HD security camera?
HD = High Definition. HD formats start at 1280×720, Known as 720P. Today’s video surveillance industry, we have analog high definition and digital high definition. Current HD resolution formats include 1.0 megapixel (720p), 1.3 megapixel, 2 megapixel (1080p), 3 megapixel, 5 megapixel, 8 megapixel (4K HD), and 12 megapixel (4K Ultra HD).
Benefits of HD Cameras
First, compared with standard definition, HD increases the size of the image, while improving the image quality through many different image enhance technologies such as progressive scanning, such as DNR (digital noise reduction), WDR (wide dynamic range), etc. HD offers superior image quality.
HD cameras can monitor a wider area than conventional CCTV camera. For example, a 12 megapixel panoramic camera can come in a fisheye lens giving you 360 degree panoramic view. Equipped with a 12 megapixel image sensor and ePTZ (virtual pan/tilt/zoom), as well as split views, it can replace several conventional security cameras; greatly reducing the installation cost and maintenance fee.
