Just wanted to share this. I’ve been using an app on my apple devices called Manything, this app lets you control the camera on one device from another device to take video or photos and store them on there server. You can watch in real time or go back and view latter. All you need are two activated apple devices. Use your buddies phone at the target and view on yours. I bought a cheap phone stand and I put a small plate in front of it to protect the phone just in case you were to hit it. The app is free and since you are using cell devices the range is unlimited as long as you have cell reception. Hope this is useful
