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.
