An example of small things that can help you save energy is, for example, avoiding opening your windows when the heating is on. Every day, not everyone is able to always remember about it – especially if there are children in the house who cannot always be fully supervised. An intelligent alarm system will help you prevent excessive heat loss. Thanks to it, each time, for example, when you want to ventilate a room where heating is turned on, and you open a window, the magnetic detectors will send the appropriate information to the alarm control panel, which will turn off the heating for the duration of ventilation. If you additionally install actuators in your windows, the system will be able to automatically close them, correlating this activity with, for example, the furnace or AC being turned on or off.
Regardless of whether you want to secure an energy-efficient or a traditional building, the alarm system design always starts with the selection of the control panel, which is when you are faced with the first dilemma – is it supposed to be a wireless or a wired alarm system? It is worth knowing that each of these options will work differently in different circumstances. If you decide to install an alarm system at the construction stage, you can choose a traditional wired installation. Installing the devices before finishing construction works will allow you to avoid additional renovation in order to connect and mask the cables. If the decision about installing a surveillance system is made later, when all rooms are furnished, and you do not plan any further renovation and construction works – opt for a wireless installation.
