What Are The Different Quality Of Surveillance Camera

12 Jan How to choose the right resolution for your security photographic camera

"Every security project is different" is ofttimes said in the technical globe. Choosing the right camera or cameras is the nigh complex decision in any video surveillance project. There are different types of cameras that can be classified by various technical aspects, such as whether they are motorized or not, or whether they allow night vision or not. On this occasion, we are going to focus on another fundamental attribute that directly refers to the quality of the captured image. We are going to explain How to choose the right resolution for your security camera.

What is image resolution

The resolution of an prototype indicates the level of item that can be observed in it. It is a term typical of digital photography and video, merely it would exist the technical equivalent to the grain of analog photography. It was formerly said that the college the number of grain an image had, the less sharp it was.

Well, that level of sharpness, quality and details that we can meet in a digital image, is precisely what we sympathize past resolution.

Digital images are no longer recorded on magnetic media like erstwhile video or photo films, but are instead made on computer bits. In digital, resolution is measured in pixels, specifically in columns of pixels (the width of the image) and rows of pixels (the summit of the image). Well, the greater the number of columns and rows of pixels, the higher resolution said image will have, the greater the level of particular it will be able to offering u.s.a..

When we multiply that number of pixel columns by the number of pixel rows, we go the unit in millions (mega) of pixels. So, for example, suppose we have an image 1500 pixels wide by 1200 pixels loftier. Nosotros would have an image with a total size, a resolution, of 1,800,000 pixels, which if we get to a one thousand thousand, would be 1.80 megapixels.

How to choose the right resolution for your security camera

One of the kickoff questions that we would have to ask a security organization installer is virtually the level of resolution that our surveillance cameras will have.

In old, analog cameras, the resolution of the image was measured according to the television lines that they could form. Thus, 480, 700 or 1000 TVL (television lines) were spoken. The more Boob tube lines, the more resolution the photographic camera would be able to achieve. It would be the equivalent of the current megapixel measurement system.

Currently, nosotros have many options when choosing a video surveillance camera. Only taking into account the resolution factor, it is normal to speak in terms of megapixels, since most of the cameras that are currently mounted are digital, although they continue to coexist with an erstwhile park of increasingly reduced analog cameras.

At this point, nosotros have to say that information technology is non all megapixels, image size, in digital cameras. We likewise have to consider other technical parameters and other important technological innovations, such as WDR, which is a engineering science that compensates for areas of more than and less calorie-free to increase the sharpness of an image.

Megapixel resolution cameras are those that have at to the lowest degree one million pixels. However, there are also cameras that, non reaching that level, are also digital because they are capable of providing a digital video output, but with a lower resolution, such equally 0.iii megapixels, for example. These cameras are cheaper and work well in certain less demanding situations.

But the normal affair, in complex security projects is to place cameras with higher resolution: ane megapixel, 2 MP, three MP, five MP and 8 MP. These would be the most mutual resolutions.

From 1 megapixel they are considered high definition, while those that reach or exceed eight megapixels already fall into the category of ultra high definition.

High definition and ultra high definition cameras are the most widely used because they attain a higher level of detail.

With loftier-definition filming, by zooming in on a face, for example, we tin can identify an individual perfectly, whose prototype has been taken from afar and who is in a crowd. This would not be possible with lower resolution cameras or older analog cameras that also did not encounter the equivalent high definition standard.

Very powerful DVR equipment is required to store all these images recorded in loftier definition, as the images have upwards a lot of space due to their high quality. Images are compressed to accept upwards as fiddling space as possible on discs. Thus, we talk about QCIF, CIF, HD1, WD1 compressions, etc.

The storage chapters is in line with the quantity and quality of the images stored. A video surveillance security arrangement relies on both technical elements: good loftier-resolution cameras and a robust recording medium capable of storing tens of terabytes of images every little time.

Benefits of loftier definition

High definition not merely brought larger images. Information technology also enabled the development of other technologies such every bit progressive scanning and dynamic racket reduction. With this, college resolution images are achieved and as well with a higher level of detail and clarity. In improver to a digital treatment that improves the prototype captured by circuitous computer postal service-processing systems.

With a loftier definition camera nosotros tin monitor a much larger area than with a conventional analog camera. This implies that we monitor more surfaces with less equipment and that the quality of the captured image is much higher.

If we add other technologies to these loftier definition cameras, such every bit a fisheye lens, we accept a panoramic camera that is capable of monitoring a 360-caste angle around information technology. If the resolution is ultra loftier definition (8 or twelve megapixels) we can cover spaces of 300 square meters with a single camera. All of this translates into lower installation and maintenance costs, equally well as less required storage space (DVR).

You already know how to cull a security photographic camera based on resolution. And the game that combines resolution with types of lenses and other technologies such every bit WDR, with which you can get a clear thought of the entire complex and heady world of possibilities that be backside a good CCTV.
