The ERIA home monitoring kit notifies you of anyone entering or exiting your property while you are away. Simply remotely connect the wireless motion sensor and wireless contact sensors to the ERIA hub to receive smartphone notifications from anywhere in the world. If motion is detected and any windows or doors break contact, you will be immediately alerted with a push notifications. For added security, upgrade your lighting to the ERIA Color A19 bulbs. These can be installed and programmed to rapidly flash red or blue if any movement is detected to deter any unwanted visitors. (ERIA bulbs sold separately) No subscriptions are required and installation is hassle free.
