    Product Description

    SimpliSafe delivers advanced security solutions that put you, your home, and your safety first. With optional professional monitoring powered by Fast Protect Technology, SimpliSafe combines innovative hardware with advanced AI and real people — for 24/7 professional monitoring that delivers fast emergency response when you need it most. The award-winning SimpliSafe system is effective, intuitive, and affordable – so that home can be safe and secure for everyone. You can protect every inch of your home. SimpliSafe has sensors for every room, window and door. HD security cameras for inside and out. Smarter ways to detect motion that alert you only when a threat is real. Hazard sensors that detect floods, and other threats to your home. Powerful sirens that can help stop intruders in their tracks. And, it’s backed by optional 24/7 professional monitoring—experts who are ready to dispatch emergency help immediately. That’s the unmatched combination that separates SimpliSafe Home Security from the others. Our bundles are designed to be effective yet affordable. And with no long-term contracts or hidden fees. This 9-piece wireless security bundle provides 24/7 protection. The Base Station is the brains of the system. It sends alarm signals to the monitoring center with a built-in cellular connection and includes a back up battery that lasts up to 24 hours and a loud, 95 dB siren. The smash-safe Keypad is soft to the touch, easy to use during the day and night, and requires no plug so it can be placed anywhere. The Wireless Outdoor Security cameras (2 total) keep watch with a 140 degree field of view, 1080p HD resolution and color night vision, and include 2-way audio so you can tell unwanted guests that they're being watched. The Entry Sensors (4 total) protect your doors, windows, and cabinets and are designed to blend into the background. And the Motion Sensor is designed for human detection, not pet detection. Advanced security, whole home protection. There's no safe like SimpliSafe.

  8. Eve MotionBlinds Upgrade Kit for Roller Blinds - White - Front_Zoom

    Product Description

    Upgrade your existing blinds and enjoy the convenience of smart shading. Control your blinds via app or Siri, or easily set schedules that automate your blinds to suit your daily routine. 

    Retrofitted smarts.

    Increase comfort and energy efficiency in your home without replacing your existing blinds. The award-winning Eve MotionBlinds Upgrade Kit makes upgrading your blinds effortless and sustainable - the easy-to-install Eve MotionBlinds motor makes your window coverings smart and integrates seamlessly into your smart home.

    Maximize comfort and convenience with schedules.

    Automate your blinds by adding schedules for workdays and the weekend, or even for each day of the week. You can then get on with your business while your blinds get on with theirs: down when the sun sets and rising when you get out of bed, or whatever time best fits your routine.

    And as all schedules are stored right on Eve MotionBlinds, your blinds can get on with their job independently of any home hub, iPhone, or internet connection. 

    via App or Siri.

    Use the Eve or Home app, talk to Siri, or control Eve MotionBlinds via the cord to set the perfect position of your blinds.

    With scenes.

    Combine multiple HomeKit-enabled accessories in a single scene and save yourself the hassle of running to and fro. A' Good Night' scene can turn on your bedside lamps, close your blinds and switch off all the other lights in your home with a single command.

    Or activate a' Welcome home' scene as soon as your Eve Motion wireless motion sensor or Eve Cam indoor camera detects any movement in the evenings, switching on lights and closing your blinds.

    When on the go.

    Wherever you are, always be in control of your home. Manage your blinds via the app and let them go up or down remotely. Thanks to the direct connection to your home hub, you're always in control of your abode (HomePod, HomePod mini, or Apple TV).

    Simple, wireless installation.

    The Eve MotionBlinds Upgrade Kit motor slides into the tube of your existing blind, replacing the existing chain mechanism. Please check if the outer diameter of your blind's tube is supported. 

    The included brackets ensure quick and stable wall mounting. You can easily add your smart blinds to your smart home by scanning the HomeKit code and following the step-by-step setup in the Eve app.
