In general, do-it-yourself solutions are less expensive, adaptable, and expandable. In addition, monitoring is a reasonable extra feature. The cost of having a system professionally installed is higher. Still, it is worth it for the ease of setup, high quality of customer service, and seamless integration of all your devices.
There is no universal solution to this problem. However, here is a general idea: While wired security systems' signals are more consistent, wireless ones are easier to set up and more flexible in their use.
Sixty percent of the thieves would check for an alarm before breaking into a home, and if they found one, they would likely move on to an easier target.
When shopping for a home security system, it's best to start by weighing the pros and drawbacks of wired and wireless monitoring, the system's security (if it's vulnerable to hackers), and the price.
