Options market security camera users the main objective of your security camera system has no well-defined and therefore, there are occasions in which do not meet their expectations creating a bad precedent and all by omitting one of the fundamental questions before installation:
What is your need to implement a security camera system? You can understand more in TOP-ENGINEERING-SCHOOLS.ORG.
To design and implement a system of video surveillance is to speak of 3 key objectives with which begins the development of a system CCTV, these are:
When we speak of a system having as object detection, as its name indicates it, what is being sought is an anomaly, person or irregular situation at the point where you want to locate the camera. Although the video capture is performed correctly, when recording in this quality is is having just 0.2 pixels/cm quality in the image, what is an too basic and often insufficient. As we can see in the image, he is achieved to detect just that there is something, but do not have a true conclusion from what is actually. This usually happens with security cameras that have a very basic resolution and just provide this amount of pixels, currently this kind of security is in a phase of total liquidation cameras.
Other parameters used for the design of CCTV systems is the recognition. So is considered a system of video surveillance with these parameters must have at least 1 pixel / cm in the image, which will provide you with a higher quality. As we see in the image, we can recognize that we have, is a person and not simple spots or distribution of colors that do not generate a clarity of what you have in the picture.
Currently these teams are booming due to their very low costs and its great resolution, in addition to its single implementation requires materials such as coaxial cable and connectors that were already used in previous systems.

Finally, due to the amount of pixels which is handled in the image is identification. This is the parameter that can provide greater definition in the image as it was expected, by the number of pixels that manages per cm. It is a quality that gives us an image much more definite and clear, allowing the full identification of the object, person, or thing that is in the image.
But the cost of installation of such equipment may not be representative, it is used in critical areas where safety is an essential value as airports, supermarkets, banks, roads, handling cash, stores, etc.

Once you have defined any of these objectives, you can define security camera will be installed.
Remember that greatest number of pixels anywhere in your image, the equipment that you will need to implement it will be of a higher range and therefore will be more cost.
But all this depends on other factors that, in upcoming blog posts, we will continue to develop.
