The act of spying on someone would likely be much more successful and effective by using something like the Smart Ball Explorer Robot. This is a small spherical device with a built-in camera that can scuttle across wood and tiled flooring while remaining unseen.
Wirelessly connect your cutting-edge espionage gadget to your iPhone and communicate with it by means of the Smartball app. Amélie Vermersch's stealthy invention can roam quietly from room to room, with you dictating its every turn and stop. Navigate crooked hallways and through doors thanks to a live video of the little droid's surroundings. The Smart Ball Explorer Robot picks up sounds and sights in spaces that are circumstantially difficult to investigate oneself. It can even be employed for playful corridor racing amongst friends.
