Hello RobertoMechea18,
Thanks for reaching Microsoft Community and posting your concern here.
Your Surface has cameras that you can use to take pictures, unlock your computer and more, These are the Windows Hello camera and front-facing camera located above the screen. The light that you're seeing is the privacy light that appears near the active camera when you're using it. The privacy light can't be turned off. Technically, the built-in IR camera is used for privacy and facial recognition for Windows Hello while the front-facing camera is mainly used for taking photos and videos.
If this answers your question, please let our Community know by marking this post as an answer. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.
