Is your friend used to live in a house of that age/quality?
A lot of people are freaked out by new noises, smells and impressions, and they can interepret them differently from you you. For instance: You are used to the smell of your house, and you might not notice the tobacco smell, that sometimes occour.
I´m not saying that the house isn´t haunted, but usually there are logical explanations. With that said; had it been me, then I would definately look into it. There is some reason for it regardless if it´s normal or paranormal.
I heard of one case where the residents of a house saw shadows and faces on the wall, and they were freaked out by it, but it turned out it was due to a lousy pain job. There are real estate agents and some engineers, that could give you an idea of what could cause it, and how it can be fixed. If you follow their advice and still have problems, there might be some more to it.
If we asume it´s paranormal I don´t think the camera will do you any good, when nothing has been seen, but sound recording might be the way. Especialla when sounds have been detected. There are other instruments that measure electromagnetic fields and thermal changes, but the easiest (and cheapest) way is definately audio equipment. As to what to use anything will go. Computer microphones and cell phones have the editing and enhancement beifits, however people seem to get more on regular cassette tapes. Maybe there is a connection between the magnetic fields an entity can cuase and the tape´s way of recording magnetism on to it.
As to wether it´s your dad or not is hard to say.
You say it´s a life-long friend. Did you dad know him? Could there be anything that your dad wants him to understand? Doesn´t have to be a bad thing. It could just as easily be a "I´m glad your here" or something.
You were the original owners to the house, but another house could have been here, so it could be someone else´s spirit.
So in short....
I would try to get a sceptical expert´s opinion at first.
I hope there is a non-paranormal explanation to it, but keep us informed.
