It's been a few decades since I've used any Norton product.
As I understand it, "SafeCam" is a component of their 360 offering, and....
You can use the interface within the "My Norton" window to either turn "SafeCam" on or off, OR grant privileges / permissions to certain applications to access your camera.
Now that you've "uninstalled" it, I'm not sure how you would be able to effectively control that feature
If it left remnants behind as is the case with a lot of these types of products you may have to re-install it and use its' interface
Perhaps use the manufacturer's proprietary removal tool in order to remove all the bits and pieces to regain normal control of your camera again.
