Our research focuses on which types of cameras are best for beginners. We chose to focus on indoor cameras, since inside is the best place to put your first one. Each camera we tested connects via a mobile app and Wi Fi. We specifically focused on fixed cameras with a wide field of view, at least 80 degrees, so they can monitor an entire room from a corner. We also researched ways to test the cameras in real world scenarios, rather than relying on confusing technical benchmarks.
