Amazon has introduced a new portal offering home security services, as reported by TechCrunch. The portal offers an array of smart security packages that include items like entryway sensors, sirens, and a video doorbell, all installed by Amazon employees and offered with no monthly contract.

There are five different tiers to choose from. The cheapest sells for $240 and is designed to create the illusion that you’re home, coming with various motion-detecting lights, smart indoor lighting, and a wireless waterproof speaker. On the other end of the spectrum, the most expensive option goes for $840 and comes with items like a smart flood and leak sensor, a Wink hub, entryway sensors, and a Ring doorbell. All the packages include an Amazon Echo Dot and two visits from an Amazon smart home expert: one to identify what your needs are, and a second to install and configure all the devices.

Amazon’s foray into providing home security packages isn’t a complete surprise. Amazon introduced its own version of Best Buy’s Geek Squad last year to offer free Alexa consultations and installations for smart home products like Ecobee thermostats and Arlo security cameras. Last December, Amazon acquired battery-powered connected camera and doorbell startup Blink, and just a few months ago, agreed to also acquire smart home company Ring for more than $1 billion.

These security packages offered by Amazon naturally include products from its portfolio (like Ring and Echo) and open up the possibility of signing up even more people to services like Amazon Key, which allows couriers to unlock your front door to place packages inside your home.

Based upon reviews, it appears Amazon has been offering these services for a few months, but it’s unclear which markets it’s actually available in, or if there are plans for a nationwide roll out.
