For target practice at long distances, use this app with almost any WIFI camera and your phone/tablet to capture, record and export your results. • Click on a previous shot capture to see where it landed. • Add marker to highlight each shot. • Export and share results as a video file, animated GIF or a simple frame image. • Works with over 1600+ cheap IP Cameras No more walking back and forth very couple of shots. Use your phone/tablet's WIFI hotspot to connect camera at ranges of 100-300ft (dedicated hotspot devices have longer range). If you need power down range, many cameras use 12v so take a car battery (use voltage regulator if needed). Great tool for archery, air and pb competition preparation and sight in.
