    Product Description

    The SwannForce has crime-fighting features other security systems dream about. Heat and motion-based activity triggers red and blue flashing lights (Patent Pending), bright spotlights and loud sirens to intimidate intruders and prevent crime from happening. Activity can trigger push notifications to let you know what’s happening and recording to ensure you have video evidence when you need it. Imagine being able to see faces, tattoos and license plates with 1080p Full HD video to actively watch over entrances, yards, driveways, parking lots, shop floors, storerooms, and customer service areas. With the Swann Security app, you can even watch live or playback video on your smartphone from anywhere in the world. In fact, you can view any of the cameras on your smart TV, and speak to see hands-free via the Google Assistant and Chromecast, Google Home Hub, or via Alexa devices. Know what’s happening at any hour with powerful infrared night vision and the ability to see color video at night. Swann’s True Detect heat and motion detection senses people and cars for more reliable monitoring and fewer false alarms.

Pressing the Doorbell and/or activity detected at your doorway triggers reliable video recording and push notifications to your smartphone. Now you can see and talk to visitors or warn porch pirates with 2-way talk from wherever you are. Mount it in minutes and you also have the convenience and flexibility of powering it using the built in lithium battery or by connecting it to your existing doorbell wires. A compact AA-battery powered chime unit is included as well which allows you to move it around the house, so you can know when there’s someone at the door without having to look at your phone.
