Doorbell Pro Power Kit???

I recently sold my home and moved with all of my cameras.I just realized that I do not have the Power Kit for my Doorbell Pro, it was left in my old house.Can I install my camera without it? I hated that thing anyway, since I installed it in the old home, the doorbell never rang properly inside the home.I have attached a photo of the chime from my new home.Please advise.
