Cameras with higher resolution have more accurate detail in the image. With analogue cameras a recorded image usually has no more than 0.1 megapixels. A 3 megapixel camera records around 30 times more detail. It is possible to record larger image areas reducing the number of cameras and the costs. Full HD CCTV cameras provide a much sharper image than on traditional analogue systems. This can lead to a better conviction rate as the evidence is much clearer.IP CCTV Cameras convert all images to data and have no theoretical limit to the resolution. IP CCTV camera systems with HD CCTV cameras are ideal for mobile monitoring and can be used from your smartphone to monitor your property even when you are on holiday.
