Finally, Z Wave and Zigbee devices use AES 128 encryption, and since they operate in a closed system with a dedicated hub, they offer more security than Wi Fi devices. Any smart security system worth its salt offers components that work
together in a seamless environment and can be manipulated using customized rules. For example, you can create rules to have the lights turn on when motion is detected, have your doors unlock when a smoke alarm goes off, and have a camera begin recording when a sensor is triggered. Some systems store recorded video locally on an SD card
or a solid state drive, while others offer cloud storage. Locally stored video is a good choice for do it yourselfers on a budget, but you have to be careful not to overwrite video you may need later. Cloud storage makes it easy to store and access recorded video, but it can cost hundreds of dollars per year depending on your subscription.
