Previously, traditional hard wired systems were considered to perform better than wireless home security systems. This was so because the sound waves of the hard wired alarm systems could travel quickly through the thickest of walls. This way all the signals reached the control center forcing the thief to go away empty handed.

However, the improvised batches of wireless burglar alarm systems have cleared the misconceptions of many people. They have proven themselves to be even more reliable than a hard wired system.
