The SecureAlert Wi-Fi NVR Security System has crime-fighting features other systems dream about. With red and blue flashing lights, bright spotlights, two-way audio, and loud sirens, you can intimidate intruders and prevent crime from happening, and these features are controllable remotely in the Swann Security app. You get free local recording for up to 180 days+ onto the massive 1TB hard drive and the option to backup video to your Dropbox account. Know what~s happening at any hour with powerful infrared night vision up to 115~/35m and Night2Day gives you amazing color video at night up to 32~/10m. Swann~s True Detect heat and motion detection senses people and cars for more reliable monitoring and fewer false alarms. The 4K Ultra HD video and powerful digital zoom, the cameras let you actively watch over entrances, yards, driveways, parking lots, shop floors, storerooms, and customer service areas. With the Swann Security app, push notifications let you know what~s happening and 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 Hey Google and Alexa devices. The cameras plug into power while their video signal back to the NVR is transmitted wirelessly, so you don~t have to worry about drilling into walls and running cables anywhere. The NVR connects to your internet router via the included network cable or Wi-Fi, while the new SwannNet technology allows you to select whether each camera connects to the NVR or your home Wi-Fi, meaning you can choose whichever network has a stronger Wi-Fi signal. This gives you greater flexibility to place the cameras where they need to be, and their robust indoor/outdoor design is built to withstand rain, snow and heat, all year round. That~s the SecureAlert Wi-Fi NVR Security System ~ it~s another example of security made smarter from Swann.
