Until recently, even the latest home security system could become obsolete overnight. But, newer whole-home integration systems are much more compatible with interchangeable parts and innovative add-ons. 
As a result, it’s now possible to have a multi-faceted security system that watches over many of the functions and activities in and around your home. For example, you can organize and control your home’s exterior cameras, motion detectors, door locks, window coverings, lighting, entertainment, appliances and HVAC with one system.
If you’re buying an entirely new system, there are many established and emerging brands available, so consider their functions, cost, convenience and reliability. But, if you want the whole-home system to manage existing utilities and appliances, things can become challenging. You will need to ensure that your specific devices can communicate with your new hub, which means you need to identify the protocol under which they can share information. Because their compatibility is not certain, it’s advisable to identify the make and model of your existing equipment and check for compatibility before you purchase a new security hub or system.
