Create video with motion tracking of 3D objects

I need to create the effect of inserting several 3D models into a video which I will provide. The length is approximately 20 seconds. The scene is a simple room with the camera moving around.

I'm very flexible and can work with a ready model and simple animation, the aim is to show the effect.
