security system house
The problem with cameras that can see through glass is that they might pick up plants moving around on a blustery day, or passing vehicles even. Again, if you want
to detect motion at a first floor window, then place the camera to one side, not opposite it. This will eliminate two problems at once. The first is that it avoids detecting irrelevant motion. The second is that it catches the intruder as they walk “across” the camera’s field of view rather than into it. Be careful when positioning outdoor cameras too, as you don’t want trees and shrubs sending you false alerts all day long. Household burglary
is defined as an illicit entry or attempted entry of a residence which usually involves theft. The illegal entry may be by force, such as breaking a window or slashing a screen, or may be without force by entering through an unlocked door or an open window. As long as the person entering has no legal right to be present in the structure a burglary has occurred. Furthermore, burglary is not only the entry of the house by itself; illegal entry of a garage or any other structure on the premises also represents household burglary. Figure1.
