Does your home already have an existing alarm system that’s less than user-friendly? The Ring Retrofit Alarm Kit DIY Setup can change that. Rather than rewiring your whole house and tossing out a perfectly good system, this DIY setup lets you make use of a perfectly good thing. With this DIY alarm kit, you can connect your existing alarm system to a Ring system. In doing this, you use the Ring app to receive notifications and control your alarm system. This sidesteps some of the larger home security companies that want you to pay to use their services with your wired system. A DIY Ring alarm kit like this comes on its own as a completely wireless system. Or you can add on the Ring Alarm Hub if you don’t have that yet.
