Night Owl is excited to offer our U.S. designed and engineered 4K UHD Bluetooth digital video recorder with wired 4K UHD spotlight cameras and pre-installed hard drive. With secure app-based Bluetooth setup, there is no need to connect a TV or monitor for setup or viewing (optional). Our patent pending recorder has built-in Bluetooth technology, making it easy for you to configure your system right from the app on your smartphone or tablet. While a TV or monitor is not required, with Google Assistant you can use simple voice commands to stream camera footage directly to your TV or monitor, all while remaining hands free. Each camera has 1-way audio (speaker) which works with our built-in siren and preset voice alerts. From within the app, you can easily activate the built-in siren, startling intruders and sending them packing. Have a guest but can’t get to them? Use a preset voice alert to let them know! Smart detection technology including human detection, facial capture and vehicle alerts reduce the risk of false alarms, keeping you safe and well protected. Facial capture lets you see who is on your property by snapping a photo and sending the image to your smart device. Motion-activated spotlights flood your yard with bright lights when human motion is detected, instantly warding off trespassers.
