Burglar alarm monitoring in South Florida - differentiate between a person and moving objects !

Burglar, fire and safety alarms are commonly found in electronic form today in burglar alarm monitoring South Florida. A system of sensor is connected to a control unit, which in turn triggers the alarm, hopefully to elicit some response. Some systems are dedicated to one mission while others handle fire, intrusion, and safety alarms simultaneously. Sophistication ranges from small, self-contained noisemakers to complicated, multi zoned digital systems with color-coded computer Burglar alarms monitoring South Florida. Many of these concepts also apply to portable alarms for protecting trucks and other vehicles.

Detectors are generally of two types: Point detectors and area (or volume) detectors. Point detectors indicate an intrusion at a specific point, and types include mechanical or magnetic contacts on doors or windows and detects when they are opened or broken. Photocell or microwave beams across pathways, pressure-sensitive mats, fiber-optic bend or stress sensors (e.g., for wire fences), proximity switches that detects large animals (humans), and vibration sensors, among others.

Area detectors indicate an intruder‘s presence within the protected area and use such technologies as ultrasonic transducers, passive infrared (heat) detectors, and microwave transducers (sometimes in combinations within one sensor). In general, area sensors detect a sudden change in the measurements being taken and triggers at some predetermined threshold.

Sophisticated computer-aided sensors include image-processing systems that detects and filter changes in a surveillance video picture (possibly using infrared or other light sources for the image), and can be programmed such that it detects or ignore different types of motions in different parts and can differentiate between a person and other moving objects. All of these sensors can be used separately or in combinations with others, often depending upon the value of what is being protected, and the budget allocated to reducing the risk of loss.
