Night Owl is excited to offer our U.S. designed and engineered 1080p HD Bluetooth Digital Video Recorder with Wired 1080p HD 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). You can easily configure your system right from the app on your smartphone or tablet with the Bluetooth connection. 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. 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.
