In short: Home technology expert Ross Trethewey demonstrates how to install a modern DIY security system. This guide covers the essential steps for setting up a hub, motion sensors, and a smart doorbell, helping you identify and protect vulnerable areas of your home without professional assistance.

The installation process begins by securing the system hub near the front door, using a specialized outlet cover plate to ensure the power connection remains undisturbed. Once the hub is registered via a mobile app, users can deploy motion sensors on door and window trim, while contact sensors are applied directly to the entry points themselves.

The project also involves upgrading traditional hardware, such as replacing an existing doorbell with a smart camera unit. Finally, the system can be expanded by placing indoor cameras in previously uncovered areas, which are activated by scanning a QR code. This approach allows homeowners to address specific security gaps through a straightforward, modular setup.
