Before buying a wireless or hardwired security system, consider the cost of maintenance.
Wireless security systems have developed slowly over the years and been utilized by professional alarm companies sparingly when wires could not be used due to cosmetic issues, limited access, etc.
Wireless home security
With the overwhelming demand for security since 9/11, the alarm industry has responded by manufacturing all wireless DIY systems to the more advanced "installer required" wireless systems. Alarm companies have paid attention and moved toward the wireless systems to increase production and reduce labor cost.
The maintenance after the sale is also a revenue generator due to guaranteed service calls to replace batteries. So, this is a pretty good money maker for the companies selling wireless alarms, right? Pay me now and pay me later. But it’s not so good for the consumer having to bear the cost of expensive equipment, batteries, securing the home and family and the future maintenance cost.

Hardwired home security
Hardwired security systems are the rocks of the alarm industry creating lower equipment cost, higher one-time labor cost and minimal to no future maintenance. Only the longer standing alarm companies offer the hardwired systems because they come from a different era when wireless was a last resort to secure a door or window in a tough spot.
So do your research carefully and ask the question, "Hardwired or wireless?" Not much more needs to be said about hardwired systems other than get yours today and start enjoying the benefits.
