Step 1:

Survey your home to determine how many windows and doors you need protect from possible intrusion. And you should write them down. Alarm company Miami Beach Coral Gables

Step 2:

Determine possible locations for the control panel. Close to the front door is a good location for a keypad. In your bedroom or close to your bed is also good. Alarm Company Miami Beach Coral Gables

Step 3:

Measure how far away the windows and doors are from the control panel. This will let you know how far the wires must go to an alarm system. Additionally, it tells you the distance a wireless system needs to communicate with sensors. Alarm Company Miami Beach Coral Gables

Keep in mind; it is difficult to install a hardwired security system in houses. Learn more about the differences between a wireless and a wired home security system Alarm company Miami Beach Coral Gables

Step 4:

Decide if you want a security system. This security systems connect to a central station that ‘watches’ your home for a monthly fee. A less expensive alternative is to install a self-monitoring system that will dial your private phone and/or other phone numbers if the alarm system triggers an alarm Company Miami Beach Coral Gables

Step 5:

Consider your family’s daily habits. Do you often get up in the middle of the night for a snack or to go to the bathroom? Do you have a pet in the house? Furthermore; Do you have valuable possessions that might need a better security, such as surveillance cameras, art protection, etc.? Alarm Company Miami Beach Coral Gables

All this influence the type of motion sensors and other security devices you need; furthermore, this tells you how they work and how you can install them. Alarm Company Miami Beach Coral Gables

Step 6:

Whether you choose a wireless or a wired system, it should be able to monitor your entire home. Each window, door, and device in the system is a zone. Alarm Company Miami Beach Coral Gables; Furthermore, the number of zones a system can control varies. For example, control panels watch up to 28 wireless zones; this is more than enough to cover a zone. Alarm Company Miami Beach Coral Gables

Step 7:

Be aware that if you choose a wired system, you need to drill holes in the walls. If you choose a wireless system, the transmission range must be large enough to cover your entire zone; and the system must be able to cover the zone farthest from the control panel. Alarm Company Miami Beach Coral Gables

Step 8:

It is important to choose a system that works with home safety sensors. Such as carbon monoxide (CO) sensors, gas detectors, flood detectors, etc. Furthermore, choose a system that can include panic and emergency buttons. Alarm Company Miami Beach Coral Gables

Step 9:

The home security system you want must be user-friendly. Verify that adding new users is a simple process . Additionally, one that everyone in the family can learn. Alarm Company Miami Beach Coral Gables

The most basic alarm consists of one or more sensors to detect thieves, and an alerting device to tell you of the intrusion. However, a typical premises security alarm employs the following: Alarm Company Miami Beach Coral Gables

Premises control unit (PCU), Alarm Control Panel (ACP), or simply panel:

The “brain” of the system, it reads sensor inputs, tracks arm/disarm status, and signals intrusions. In modern systems, this is typically one or more computer boards, along with a power supply. Alarm Company Miami Beach Coral Gables


Devices that detect intrusions. Sensors go in the protected area, within it, or both. Additionally, sensors can detect intruders by a variety of methods. Such as monitoring doors and windows for opening. Additionally, by monitoring unoccupied interiors for motions, sound, vibration, or other disturbances. Alarm Company Miami Beach Coral Gables

Alerting devices:

These indicate an alarm condition. Most commonly, these are bells, sirens, and/or flashing lights. Alerting devices can warn the occupants of intrusion and potentially scaring off thieves. You can use these devices to warn occupants of a fire or smoke condition. Alarm Company Miami Beach Coral Gables


Small devices, typically wall-mounted, which function as the human-machine interface to the system. In addition to buttons, keypads typically have indicator lights, a small display, or both. Alarm Company Miami Beach Coral Gables

Connections between components this may consist of direct wiring to the control unit or wireless links with local power supplies. Alarm Company Miami Beach Coral Gables

Security devices:

Devices to detect entry or movements such as spotlights, cameras & lasers. Alarm Company Miami Beach Coral Gables

In addition to the system itself, security alarms work with a monitoring service. In the event of an alarm, the control unit contacts a central monitoring station. Alarm Company Miami Beach Coral Gables

Furthermore, operators at the station see the signal and take appropriate action; such as calling the property owners, notifying police, or dispatching private security forces. Alarm Company Miami Beach Coral Gables

Sensor types

Hermetically sealed reed switches

The hermetically sealed reed switch is a very common type of sensor. Furthermore, it operates with an electrically conductive reed switch. Consequently, it it either normally open or normally closed when under the influence of a magnetic field. This happens in the case of proximity to the second piece which contains a magnet. Alarm Company Miami Beach Coral Gables

When the magnet is moved away from the reed switch, the reed switch either closes or opens, again based on whether or not the design is normally open. This action coupled with an electric current allows an alarm control panel to detect a fault in that zone or circuit. These types of sensors are very common, and you can wire them directly to an alarm control panel. Or you can typically find them in wireless door/window contacts as sub-components.

Passive infrared detectors

A passive infrared sensor used to detect motion

The passive infrared (PIR) motion detector is one of the most common sensors found in household and small business environments. Consequently, it offers affordable functionality. The term passive refers to the fact that the detector does not generate its own energy; it works entirely by detecting the heat energy off other objects.

Alarm Company Miami Beach Coral Gables

Strictly speaking, PIR sensors do not detect motion; rather, they detect abrupt changes in temperature. Therefore, as an intruder walks in front of the sensor; the temperature at that point will rise from room temperature to body temperature…;, and then back again. Furthermore, this quick change triggers the detection. Alarm Company Miami Beach Coral Gables

PIR sensors can be wall- or ceiling-mounted; and come in various fields of view, from narrow “point” detectors to 360-degree fields. Additionally; PIRs require a power supply in addition to the detection signaling circuit. Alarm Company Miami Beach Coral Gables

Infrasound detectors
The infrasonic home security system

The infrasound detector works by detecting infrasound, or sound waves at frequencies below 20 Hertz. Alarm Company Miami Beach Coral Gables Alarm Company Miami Beach Coral Gables

Sounds at those frequencies are inaudible to the human ear. Furthermore; due to its inherent properties, infrasound can travel distances of many hundreds of kilometers. Therefore; infrasound signals can result from volcanic eruptions, earthquakes, gravity waves, opening and closing of doors, forcing windows to name a few.

Alarm Company Miami Beach Coral Gables

The entire infrasound detection system consists of the following components:

  • A speaker (infrasound sensor) as a microphone input.
  • An order frequency filter.
  • An analog to digital (A/D) converter.
  • An MCU processor you can use to analyze the signal. Alarm Company Miami Beach Coral Gables.

Each time a potential intruder tries enter into a house; he tests whether you closed it. He uses tools on openings, or applies pressure. Therefore, he creates sound vibrations. Consequently, the infrasound detector detects such actions before he breaks in. Alarm Company Miami Beach Coral Gables

The primary purpose of such system, is to stop burglars before they enter the house. Consequently, they help avoid not only theft, but vandalism. You can modulate the sensitivity depending on the size of a house. And of course, if you have pets. Alarm Company Miami Beach Coral Gables

Ultrasonic detectors

Using frequencies between 15 kHz and 75 kHz, these active detectors transmit sound waves. The Doppler shift principle is the method of operation. Furthermore, it states, an object motion generates a change in frequency.

The ultrasonic detector operates by the transmitter.

Solid objects reflect the sound waves (such as the surrounding floor, walls, and ceiling). Consequently, the receiver can detect them.

When the surfaces are stationary, the frequency of the waves will be equal to the transmitted frequency. However, a change in frequency will occur as a result of the Doppler principle; when a person or object is moving towards or away from the detector. Such an event initiates an alarm signal. This technology is obsolete by many alarm professionals.

Microwave detectors

This device emits microwaves from a transmitter and detects any reflected microwaves or reduction in beam intensity using a receiver. Additionally, they come inside separate housings (bistatic) for outdoor applications. Furthermore, to reduce false alarms this, type of detector comes with a passive infrared detector or “Dualtec” alarm.

Microwave detectors respond to a Doppler shift in the frequency of energy; by a sudden reduction of the level of this energy. Consequently, Any of these effects may indicate motion of an intruder.

Compact Surveillance Radar

Compact Surveillance Radar emits microwaves from a transmitter and detects any reflected microwaves. They are similar to microwave detectors but can detect the precise location of intruders in areas extending over hundreds of acres. With the capability of measuring range, angle, velocity, direction, and size of the target, a CSR is able to pinpoint a precise GPS coordinate of an intruder.

This target information shows on a map, or situational awareness software. Consequently, they define alert zones with different types of actions; depending on the time of day and other factors. Furthermore, CSR is common to protect outside the fence line of critical facilities; such as electrical substations, power plants, dams, and bridges.

Photoelectric beams

Photoelectric beam system detects the presence of an intruder. They do it transmitting visible or infrared light beams across an area; specially where something obstructs these beams. Furthermore, to improve the detection surface area; the beams are together in stacks of two or more. However, if an intruder is aware of the technology’s presence, you can avoid it.

The technology can be an effective long-range detection system; if you installs it in stacks of three or more. . Furthermore, systems are available for both internal and external applications. Additionally, to prevent a clandestine attack that uses a secondary light source to hold the detector sealed,…; whilst an intruder passes through; most systems use and detect a light source modulated.

Glass break detection

The glass break detector is common for internal perimeter building protection. Furthermore; glass break acoustic detectors are in close proximity to the glass panes; and it listen for sound frequencies that means glass breaking.

Seismic glass break detectors, or “shock sensors”. are different. As in, you can find them on the glass pane. When glass breaks it produces specific shock frequencies; they travel through the glass and often through the window frame; and the surrounding walls and ceiling. Typically, the most intense frequencies generated are between 3 and 5 kHz; depending on the type of glass and the presence of a plastic interlayer.

Seismic glass break detectors “feel” these shock frequencies and in turn, generate an alarm condition.

Window foil is a less sophisticated, mostly outdated, detection method. Furthermore, it involves gluing a thin strip of conducting foil on the inside of the glass. Additionally, putting low-power electric current through it. Furthermore, breaking the glass tears the foil and break the circuit.

Smoke, heat, and carbon monoxide detectors

Additionally, most systems have smoke, heat, and/or carbon monoxide detectors. Additionally, you can also call them 24-hour zones (which are on at all times). Smoke detectors and heat detectors protect from the risk of fire. Additionally,  carbon detectors protect from the risk of carbon monoxide. Although an intruder alarm panel can have these connected; it may not meet all the local fire code requirements of a fire alarm system.

Additionally, traditional smoke detectors are technically ionization smoke detectors. Furthermore; this “create an electric current between two metal plates; which sound an alarm when disrupted by smoke entering the chamber” .

A newer and perhaps safer type is a photoelectric smoke detector.

Furthermore, it contains a light source in a electric sensor. “Normally, light from the light source shoots straight across and misses the sensor. When smoke enters the chamber, it scatters the light, which then hits the sensor and triggers the alarm.”
