LONGSHOT's wireless, portable, and battery powered target camera systems 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.

No cell or WiFi service is required. You'll have live HD video at your fingertips, making it easy to see where your shot are hitting. Seeing your shot has never been easier.With this bundle you are able to have 2 extra cameras along with your system. You are able to set up these long range shooting cameras at other locations or distances and connect to the receiver over WiFi.
