Still, there’s something that feels quite nice about being able to install the system yourself and to get it working right. Some security systems require incorporating your new system with your existing wiring which means you will need to have the right tools for the job. Anytime you’re dealing with wiring and electricity, you really need to know exactly what you’re doing and have the tools to do it properly. Otherwise, you could end up damaging your new equipment, your existing wiring, or creating a fire hazard if it is not installed properly. So unless you truly know what you’re doing, you should probably opt for professional installation, especially if your new security system will need to be hardwired. If you choose a DIY wireless security system, most on the market today are fairly intuitive and easy to install. And, many of them don’t require any special tools or knowledge to get the job done. Whether you’re a senior or simply buying a security system for a senior, I’d recommend Vivint. They have professional installation, so you won’t have to worry about your system working correctly; the person who installed my system was very kind, patient, and most importantly, knowledgeable. This could be very helpful for a senior, who may not know much about modern DIY installation. Aside from that, Vivint has one of the highest rated security apps in the Apple and Google Play stores, so you can rest assured that it’s easy to use, even for someone not super tech savvy.
