Introducing Night Owl's state-of-the-art Smart Detection Security System with Integrated Battery Backup. Not only does this system utilize Dual Sensor Technology to ensure that you are alerted to actual threats or meaningful events, it also incorporates a built-in battery backup system that enables the unit to continue recording for up to 2 hours after power loss. Our Dual Sensor Technology with Integrated Battery Backup truly takes security to the next level! By incorporating infrared sensors into the 1080p cameras, this system utilizes both motion detection and heat detection to minimize false alerts and keep you apprised of Real threats in Real time. Further, the DVR serves as the hub of power for every camera and houses the battery backup component. It truly is an all-in-one solution! These premium cameras use a passive infrared sensor to detect heat produced by humans, animals and vehicles. Whereas heavy rain, bugs and changes in lighting could potentially produce motion alerts on older systems, this new technology requires both changes in motion and heat be detected simultaneously. Not only does this one-of-a-kind technology significantly reduce the number of false alerts you receive, it also conserves hard drive space. This guarantees that you are made aware of those threats that pose the greatest risk to you and your loved ones without having to sift through unnecessary recordings.
