how to stop/disable animation/animator on trigger in another gameobject?

is there anyway i can stop/disable the animator on trigger without resetting the frame? i tried using MyCameraAnimation.gameObject.SetActive(false); but it didnt work and just gave me an error MissingComponentException because the animator is in another gameobject (the camera) not in the gameobject where the script suppose to disable it in (and yes i already have the Get.Component(); in the start method but it just gave me that error)
