The video surveillance system for "Dummies" Today, the monitoring system are no longer part of spy stories. The cameras can be found in almost all banks, supermarkets, cinemas and restaurants. Some of them striking, and the existence of others, you do not even know. Certainly, the surveillance camera is able to significantly increase the effectiveness of your security. One camera presence can deter potential intruders and force them to renounce their intentions.
Under present conditions the cost of surveillance systems has decreased so much that it can afford to purchase even a small company with low incomes.

For starters, before buying, you need to answer the following questions: For what purpose acquired camera? The area for which you plan to watch? Where will the camera: in a room or open space? What are the conditions area (lighting, visibility, pollution, etc.) Is there in the hedges, or tall objects that may interfere with monitoring? How will the camera, overtly or covertly? Will the camera is mounted statically, Or should they move? It is also necessary to determine in advance the trajectory of the camera (in a circle, capturing a certain angle in the vertical / horizontal). Do you need to keep the camera could increase / decrease the image? Where will be located observation point for the cameras? As far as it is removed from the cameras? Do you need to view the images simultaneously from multiple cameras or enough alternate views? Do you plan to record images from the cameras? If so, how many hours per day will be the recording? How long will store archives of records? Simplified surveillance system looks like. Lens The lens is designed to catch the light, reflected from the subject and focusing it on a surface that is sensitive to light (integrated circuit or the receiving tube cameras).
