Best Camera for the Job?

Hello,

My company is building a new building in a nearby city, and they want a time lapse of the construction. It will happen over one year, and I have to mount the camera to a telephone poll across the street.

What would be the best Camera? It has to be waterproof/coldproof as we do have some hard winters.

Also, what sort of mount would I need to mount it to a telephone pole?

Any help would be great, I need to make the purchase ASAP.
