There are also financial advantages. Many insurance companies offer discounts on home insurance premiums when homeowners install an alarm system or security equipment. Self monitoring or professional system?As more home automation technology emerges, a growing number of homeowners are opting for self monitored security equipment over systems that are monitored by professional security companies. Indeed, nearly half of Americans 49 percent say they are open to installing their own home security system, according to a 2016 LivSecure survey. Of course, there are pros and cons of taking this DIY approach. Because there's no monthly fee, many self monitoring systems are cheaper than professional home security systems. Proponents also say self monitoring versions give homeowners a better sense of control over protecting their domain through access to live video feeds, mobile alerts, smartphone technology and other self monitoring tools. Still, a traditional, professionally monitored home security system has advantages. Professional security systems will automatically alert authorities in an emergency situation, such as a break in or a fire. With self monitoring systems, you have to make the call. Also, with a security provider, "you have someone to contact should your system have any kind of service issues," Walters says.
