Inner10 Target Camera allows you to turn your old phone into a target camera system. Before you install, it's important to read the tutorial. It'll explain what additional hardware you'll need and what are the maximum shooting distances for various hardware configurations.

Our system requires 2 phones and 2 applications:
• https://play.google.com/store/apps/details?id=mobidev.apps.targetcam.camera
• https://play.google.com/store/apps/details?id=mobidev.apps.targetcam.monitor
• Live stream and photo mode.
• It's possible to compare two last photos to 'blink' the new hole.
• Wi-Fi (up to 50-100m) and mobile data supported.
• Off-center zooming.
• High image resolution (as much as your phone camera supports).
• Low display lag.
• Perspective correction – this application can remove the skew that comes from placing the camera at an angle to the target.
• Optimized network usage - as a rule of thumb this application will use 4 times less data then a generic camera application.
• No mirage issues – unlike a spotting scope.
Currently this application is free and without any ads. However we reserve ourselves the right to change it in the future.
