HikVision Dome or Turret

Hi all
I have my large building yard I need to cover the area with CCTV due to issues, I am looking at the HikVision Turbo Coax range, due to the distance between the recording unit and some of the cameras it will be quite straight forward I am looking at the following, some of the cameras are going to be fitted to upright poles on a mount and others on the building would you recommend dome cameras or turret?
