Waterproof, wireless backup camera with night vision has a 120-degree viewing angle and motion detector to minimize blind spots and prevent accidents. CMOS sensor creates high-quality digital video. IR cut filter blocks infrared light in daylight. Built-in Microphone on Camera The camera has a built-in microphone that picks up audio and sends it to the monitor on your Vision S wireless RV backup camera system (sold separately). This allows your friend or family member to relay information and instruction to you, providing peace of mind as you work together to safely maneuver your RV. Motion Detection When used with your Furrion Vision S wireless RV backup camera system (sold separately), the motion detect feature allows you to set the motion sensitivity level of your camera to low, medium, or high. On the low setting, your camera will not detect a pesky raccoon until it's very close or already in your garbage, whereas on high setting, it will detect the raccoon approaching from further away. Your monitor will automatically illuminate to alert you once motion is detected.
