Sorry for being that guy but if possible you should always refrain from using Wifi for applications in production, safety and security. Too many known and unknown vectors to its reliability.
But yea, I get it. Most people don't know the details and on the overall market most affordable devices and services for security systems are some semi-"smart" products which are simple to set up. The extra work and cost that come with professional equipment aren't really appreciated, eapecially by those who don't know any better.
