Proudly American, Night Owl is excited to offer our U.S. designed and engineered wired 4K UHD 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.
