Proudly American, Night Owl is excited to offer our U.S. designed and engineered Wired 1080p HD Add On Spotlight Cameras with Preset Voice Alerts and Built-In Camera Siren. Each camera has 1-way audio (speaker) which works with our built-in siren and preset voice alerts. When used with a compatible recorder, 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 (DVR sold separately). Motion-activated spotlights flood your yard with bright lights when human motion is detected, instantly warding off trespassers. These weather-resistant indoor/outdoor cameras provide the coverage you need for your home or business with up to 100 ft. of Night Vision and wide-angle viewing. A secure wired connection delivers uninterrupted viewing and recording, providing you with true around the clock protection. When you connect these add on cameras to your existing recorder, our free remote viewing app for iOS and Android Smart Devices keeps you connected and provides easy access to your recordings. NOTE: These cameras are not for standalone use and must be added to a compatible Night Owl BTD2 or BTD8 Series DVR.
