Such a slow ninja....*facepalms* Sharingan 1 tomoe is this
Description: This type of Sharingan has 1 tomoe. It allows the user to perceive motions. An example of this was in the battle between Sasuke and Haku. Sasuke could see Haku's attacks coming. The user's pupil turns bloody red, and gains an extra pupil, or tomoe within each eye that will surround the original, centered pupil. When active the user now has the ability to track speeds that normally cannot be seen by the regular human eye. They also gain the ability to see through visual D rank genjutsu and can predict most taijutsu and ninjutsu movement and technique, allowing one to be able to react best to the situation.
were going to amplify it by tracking chakra (with sharingan), Viewing heat sources (with sharingan), and slight movements of any thing(with sharingan)
That is how sharingan can track a ninja
