Smart Home System

H4 Plus

The H4 Plus WiFi / Cellular Smart Home System is ideal for your home security. When doors/windows are opened or when motion is detected, it sounds a loud siren on site to deter would-be intruders and sends text and email notifications and makes calls to your and your family's pre-authorized phone numbers.

Sharing Devices With Family Accounts

Everyone in the family can have their own account for free. The person who sets up the H4 Plus is the Main Administrator, who can then share device access with family accounts with two levels of access rights - Admin or User. Admin will have full access rights, except for re-sharing the devices, while User will only receive alerts and edit their own account information.
