The evolution of wireless security has been significant. In the past, the majority of the alarm systems we set up were hardwired safety systems. What is the reason? Since that was the only thing available. We recall the process of making holes for keypads, door contacts, motion detectors, and finally, the siren was installed. We utilized lengthy drill bits and connected wires to all components. Crawling through attics and crawl spaces was necessary to install all the wires, and during the summer it was often extremely uncomfortable.
