Nest wants to manage every aspect of your home's security -- not just its thermostats and cameras. The company has announced a slew of products designed to keep an eye on your home while you're away, under the Nest Secure banner. That includes a Google-Home-looking Guard control system, Detect sensors (placed in rooms, near windows and doors) and a Tag keychain that arms and disarms the security hub. The starter bundle will cost $499, with extra Detect sensors running $59. Need an additional Tag for your roommates or kids? Those will set you back $25 each. A bundle with the Nest Cam Outdoor (this is different from the latest Nest Cam IQ Outdoor) will be available at Best Buy as well as Nest's website for $598.
