The role of security and protection is a serious one. The existence of crime makes us all potential victims and obliged to recognize that to some extent we are all vulnerable. Crime is all too graphically described every day in our newspapers and on our televisions.

This can be done in a number of different ways but installing surveillance systems Miami is probably the most effective method. Everyone who owns property or goods can be a victim of the thief and no one is immune from the possibility of being violated by the burglar. Therefore it is up to the individual to reduce the chances of becoming a statistic.

The thief can always make the most of a quick opportunity so it is essential to make life difficult for the intruder and prevent him/her from being able to act in an expedient manner.
Very often an intruder alarm system can be integrated with a fire alarm system, but in this chapter we intend only to show how property loss can be prevented by means of an intruder or burglar alarm system. A basic intruder alarm system consists of a number of detection devices, a control panel and signaling devices such as sirens or bells. The system may also be connected to a telephone line to provide remote signaling.
Every element in the system has its own specific function and is carefully designed to blend into its surroundings to give a consistent, reliable and trouble-free performance. Detection devices are intended to recognize attempted intrusion. They consist of components which are strategically placed around the premises to be protected, dividing it into zones or areas. For instance in a house, the living room, kitchen, garage, main bedroom and secondary bedrooms can all be planned to operate on different zones.
Specific zones can be protected or left unarmed at any given time, depending on the configuration the homeowner chooses. The method of establishing zones is dealt with at a later stage, but at this point we shall look at detection devices in some detail. Detection devices play many diverse roles but fall into two main categories. Perimeter detectors such devices sense attempted intrusion. Surveillance systems Miami such as motion detectors devices sense movement in a protected zone or area.
Magnetic reed switches is one of the most basic perimeter devices is the magnetic reed switch. Switches intended to protect opening doors or windows are normally of the closed magnetic variety. Basic versions are encased in plastic and consist of a metallic arm which closes the contacts when a magnet is held in close proximity to the switch face. For heavier duty, metal cased switches are also available for use in harsh atmospheres or where the switches may be subject to abuse, such as in an exposed position.
