It may be fine for your father, but I would say there are 2 limitations with this camera.
First of all it takes 2 x AAA batteries. I think it will go through batteries at an alarming rate.
Not sure if rechargable are supplied, but if not I suggest you get some re-chargable batteries and a charger.
Secondly, it has a digital zoom and not an optical zoom.
A "proper" zoom is an optical zoom where the lens moves in and out and you get the same quality picture if the zoom if fully in our fully out.
All digital zoom does is enlarge the centre of the picture, making it SEEM you are closer, but all it is doing is reducing the quality of the picture. To be honest, digital zoom is almost a waste of time.
