The Moultrie X 6000 Series Cellular Camera is a game camera and cellular modem in one unit. When wildlife walks in front of the camera, the PIR sensor detects the motion and triggers the camera to take a photo. The cellular modem portion of the trail camera then transmits the digital image via the Verizon 4G or the AT&T 4G network (depending on the option chosen) to the Moultrie Mobile cloud-based server. Once uploaded to the server, the image is viewable on the free Moultrie Mobile app or by logging into your online account via a computer. This trail camera has an advanced flashed technology that features a Long-Range 850nm Infrared, LED/24 flash. With the Illumi-Night Sensor, nighttime images that are taken with the Moultrie 6000 Series Game Camera are just as bright and clear as the daytime photos. (VERIZON CARRIER)
