This I bought to enhance my security however it’s not easy to install if your outside door facing is not wide, which mine is not. It has a magnet which will attach it to a steel door, which I have but then you have to use it with battery only and it’s easy to remove. I have a Nest outside camera which is much better. It disconnects from wifi. I basically tried to use it but still trying to decide if I will keep it. Measure your outside door facing if it’s wooden to make sure it’s as wide as the bracket. They make a narrower one but I haven’t checked it out. I bought this to replace my nest camera so I could relocate the camera.
