Short Answer:No

Long Answer:
Wired system is sometimes more secure than a wireless one because to crack a wired system it needs to be physically accessed which can be tough whereas in a wireless system a person only need to crack the wireless signals which can be accessed outside the intented secure area.
Another point is we can determine easily if someone has breached a wired system because of physical damage whereas in a wireless system the security breach can go undectected for a long time.
