The Pixel Live View Remote Control Wireless Expert allows you to wirelessly control your camera from up to 200 meters away while still utilizing the live view function. The Pixel Expert receiver has a 3.5? TFT monitor as well as a built in speaker. The transmitter, which is mounted to the camera, has a built in camera with CMOS lens. This lens is essential for cameras that do no support the Live View function as the connected receiver displays a preview of how your image may turn out.
