Have you ever wondered what are the security alarm components ? That is, how do they manage to work that way being such small and apparently simple devices? If you've never done it, maybe now is a good time to start.
After all, you are delegating. the protection of your home o your business to the contracted alarm. Know its internal functioning and the role that each element of the system has.hardwareIt is vital to understand the reason for the breakdowns and the very limits of the device.
As we explained in another previous article, the first alarm in history was very simple. August Russell Pope invented a battery-powered device that reacted by closing an electrical circuit to which the doors and windows were connected in parallel .
When you open one of those items the circuit was cut causing the internal magnets of the alarm to begin to vibrate. These electromagnetic oscillations were passed to a hammer that hit the bell responsible for the sound. And little else.
As you can see, the components of security alarms in the 19th century were very simple. Luckily, technology has advanced and today these devices are much more complex and precise .
The problem is that no one cares to explain it. Selling is more important than truly protecting customers. Let's get into it with the components of modern security systems.
Basic parts of a security alarm
It is necessary to distinguish well between security alarm components accessories and critical parts . Both come together in the effective operation of the device, but it could not operate without one and could operate with the other.
Of course, let's start talking about all that hardwarey softwarevital of the protective device. These, regardless of the brand, are present in all models in the sector.
Control unit: the brain of the alarm
It is the processor of your mobile or your computer; the central hub through which all theinputsy outputsof the safety device. That is why the central unit is usually called “ alarm brain ”.
This component is no longer a processor that has attached a motherboard , a memory and other modules dedicated to alarm control ; keyboard, biometric identification system, etc. Obviously, for all this to work, there is an electrical connection and a battery for possible outages.
In the central unit there is also stores the information which will later be used to analyze possible thefts, activate specific areas of the home, adjust programming or configure responses conditioned toinputs.
Logically, thehubis the one that communicates remotely in a stable and secure way with the different detectors of the system . They are usually connections of just seconds that operate at modulatable frequencies in case of possible inhibitors.
Power supply
What would be of a machine without power. For it to work, one of the components of the security alarm must be dedicated to connection to the electrical system of the home or premises. This is how all modern devices work.
Speaking of the protection device, we find a feeding system dedicated to the different sections of thehardwareand another to the control panel. The voltage peaks and other voltage variations depend on them. don't mess up the alarm .
Needless to say, the power supply has Integrated UPS to guarantee the operation of the device in situations of lack of current. Arehackingyour alarm? This technology will allow you to continue accessing it without problems.
Detection elements that an alarm may include
So much for the components of security alarms that are essential. You will have already seen that each company offers devices with different functionalities . That's because we are already in a section of thehardwareoptional.
Here the manufacturer will include what it believes is necessary according to the objective of the product. The list of sensors and detectors What can include an alarm is almost infinite, but it doesn't hurt to do a little review.
- Magnetic switch: a kind of button intended to identify the opening of doors and windows.
- motion detector: component capable of capturing temperature variations and/or movement of objects through electromagnetic waves.
- Infrared barrier: transmitter connected to the alarm that serves for perimeter detection of outdoor areas.
- Impact or vibration detector: very thin and insulated sheet capable of detecting minimal vibrations of a surface. When a limit is exceeded, they contact the central unit to activate the alarm.
- Glass break detector: microphone associated with a chip that limits its functionality to a specific range of decibels. Exactly those emitted by breaking glass.
- Smoke detector: component capable of identifying fires by measuring the level of suspended particles in a specific room.
- Moisture detector: sensor capable of preventing flooding by identifying certain levels of humidity on a specific surface. The warning light goes off when the limit is exceeded.
- limpet sensor: detects changes in temperature or movement normally attached to safes.
- Videodetector: motion sensor coupled to a color camera and night vision. It activates when it senses an intrusion and captures images to alert the alarm.
Alert components
We have not included them in the part of security alarm components basic because they can also vary depending on the model and brand. We refer to the elements responsible for emit the alarm signal .
The most common thing is to find a mermaid prepared to emit a powerful and unpleasant sound. This serves as deterrence tool warning the thief that he has been identified. There are them for both indoors and outdoors.
The alternative is la silent alarm . That is, the one that does not have a siren. That doesn't mean he doesn't warn the police, it just means he does it quietly. They are, therefore, much more effective in stopping thieves without attracting attention.
Based on this security approach, we can distinguish two types of components:
- Deterrents: These are the signs that warn both the tenant and the thief. The aforementioned sirens are included, but also the lights and deterrent plates . His mere presence already puts off more than one criminal.
- Active protection elements: They are focused on the immediate protection of the home. It can be either a fog system or one to alert the police or firefighters. Security cameras are also framed here.
Control keyboard
Touch panel placed in an accessible part of the home from which the user can turn off, turn on or configure the parameters of the security alarm. Its size and design depends on the brand and the installation company.
Older models include physical buttons to handle it. The most recent ones, however, have replaced the entirehardwareby a smooth surface that is activated by touching with your fingers.
Communicator
Who alerts the Alarm Receiving Center or the police. Up to this point we had seen the elements that detect the intrusion and those that emit the signal to warn. But not the component in charge of making it available to the CRA and other third parties involved.
The most common communicator is the one who works through the telephone line, although in recent years the IP communicators and GRPS . The variety gives the possibility to avoid the hacking methods of thieves.
