The DXR-8 Video Monitor by Infant Optics is the first baby monitor with interchangeable lens technology. Three separate lens types - Normal, Wide Angle (sold separately), and Zoom - allow you to choose the most suitable focal length and viewing angle for the specific environment, just like a professional camera system. Video is streamed in real-time to a compact 3.5" LCD color display providing a crystal clear image. The DXR-8 is packed with a roster of advanced features for added convenience: remote camera pan/tilt, infrared night vision, talk-back function, room temperature sensor and more. This camera is an investment that grows with your family. Use a close-up lens for intimate vision of your infant, and swap for a wide-angle lens when your child becomes more mobile to provide a full view of your child's activity.
