Different types of existing alarms

Nowadays, safety should be one of the main concerns of all families, not only in their homes, but also in commercial spaces. Making sure your values and your family are completely safe should be one of the main concerns for you, so alarm systems are becoming more and more common.

There are currently several options available for alarm systems, each with its own characteristics that need to be analysed individually so that you can choose the most appropriate one to ensure your safety.

Learn more about the most common types of alarmsysteem and find out which one suits you best! Simple or highly technological, find out which alarm system is right for you.

How to buy an alarm system
There are different types of alarms and security sensor systems on the market. Choosing the best one for your needs is not always easy.

A good start is to know that the bigger the technology, the better the answer to protect your assets. Knowing the options for perimeter security is the first step to understand which one responds better to the risks that the company or the property is running.

Then get to know the types of alarms and security sensors that exist and the areas indicated for each.

Most common types of alarms

Passive infrared alarm system
This alarm is capable of detecting body heat by means of infrared energy. The system identifies the presence of an intruder, even in poor visibility. Although it is an economical solution, as it is very sensitive, this equipment can issue a false alarm in places with large temperature fluctuations. It is indicated for internal areas with low temperature fluctuation and little movement.

Dual technology: passive infrared and microwave
This system combines infrared technology (temperature detection) with microwave technology. Microwaves identify the movement of the body through the baptismal effect, a kind of radar that emits pulses and analyzes the received signals.

This combination avoids false alarms, because activation only occurs when both sensors are activated at the same time. This type of sensor offers options suitable for different environments, whether they are internal, semi-open or external.

Active infrared
Also known as a barrier sensor, it creates infrared waves between two ends, avoiding invasions. The more advanced ones have filters to avoid mechanisms that light it up. It is suitable for walls of houses and industries

Temperature compensation
It detects the variation in ambient temperature and adapts to it, preventing false alarms. As with other technologies, infrared can be adjusted to detect even the presence of people camouflaged with thermal clothing, for example. It is most suitable for banks and commercial institutions.

Pet alarm
It has the ability to identify small bodies by infrared. It is classified by weight and does not pick up movements made near the ground. The most advanced are able to detect animals weighing up to 46 kilos, enabling them to distinguish a person from an animal in this weight range.

It is especially useful for places where animals circulate, which ultimately leads to many false alarms. Industrial plants or large agribusiness units can benefit from this feature. The system recognises and ignores pets and only activates alarms when it identifies the presence of humans.

Ceiling sensors
Alarms with ceiling sensors have a 360 degree detection field. Their coverage area can vary depending on the height of the ceiling. Indicated for the interior of buildings.

The application of each alarm sensor is conditioned to various factors such as the routine of the place, the exposure of the environment to external factors such as solar heat, insects, animals or even machines that can heat up at night causing the alarm to go off. Therefore, it is important to calmly analyze the options and seek the help of experts when purchasing the alarm system.

Installer alarm systems
It is advisable to look for an installer alarm system for advice and installation, as it is necessary to take some care during installation (so that later on no safety leaks will occur due to poor installation).

Maintenance must be carried out periodically (in some cases it may be necessary to replace the batteries several times a year).

If you do not have the necessary knowledge, it is best to hire a specialist company that not only installs the equipment professionally, but is also responsible for regular maintenance and inspection, 24 hours a day.
