LONGSHOT's wireless, portable, and battery-powered target camera systems are set up adjacent to your target and 10-15 ft. back; the long-distance wireless camera can be moved within that range to adjust the field of view. Since the long-range wireless camera is positioned down range by the target, you'll never have to worry about fighting mirage to see your shots again. With a runtime of 9+ hours, LONGSHOT LR-3 cameras allow you to view the target remotely on your tablet or phone via the easy-to-use Longshot app (track and number shots, save photos, review sessions, record video, and stills). No cell or WiFi service is required. You'll have live HD video at your fingertips, making it easy to see where your shot is hitting. Seeing your shot has never been easier.With this bundle you are able to have 3 extra cameras along with your system. You are able to set up these cameras at other locations or distances and connect to the receiver over WiFi.
