Alarms and security systems to be installed in offices, business premises and private homes. These are self-installing alarms made up of everything necessary to carry out an initial installation with expansion possibilities by adding more sensors. It is mistakenly believed that alarm signal receiving companies offer greater security to the user. The only thing these companies do is install an alarm and act as intermediaries between the alarm and your mobile phone when an incident occurs. With these alarms, your mobile phone acts as a reception center for alerts, eliminating intermediaries and the high associated costs of first installation and monthly maintenance. In this section you will find alarms that have a connection by basic analog telephony or fixed telephony.
