The recording standard 1080N
– is a new technology for budget segment of AHD video surveillance, which allows producing a recording with a resolution of 960 х 1080 pixels by 1/1.3-megapixel DVRs. In other words, that means that you can connect 2-megapixel AHD video cameras to low-cost video recorders and receive a sufficiently detailed video image, previously available only to FullHD devices. The new standard is now replacing a 1-megapixel (720P) digital-analogue video surveillance, and it promises to replace it soon completely.
Why do you need it? Firstly this allows you to save significantly on the purchase of a DVR – the difference between the image in 1080P (FullHD) and 1080N standard in practice is indistinguishable. However, there is a difference in price – more “advanced” FullHD DVRs are much more expensive. Secondly, you can spend the saved on DVR sum of money on more expensive video cameras, and, therefore, get a better and more detailed video for the same money. It is only necessary to remember that 1080N DVRs record in the resolution of 960 x 1080 when 2 Megapixel AHD video cameras are connected to them, but not in the resolution of 1920 x 1080 pixels. Thirdly, you can simultaneously use video cameras of different resolutions at the site: for example, simple 1-megapixel for a general review of the territory, and more upscale 2-megapixel devices to monitor the more important site to record such details as car number plates or faces of visitors.
