We need some help in choosing between a Honeywell Fusion DVR with HD4U cameras for an aquatic center and a Pelco DX8100 DVR system with IS310 camewras. Both are within a few thousand in price but but having difficulty in system feartures, viewing of patrons for accidents and loss prevention, and understand lenses. We have tall ceiling heights of 22 feet and low water features which we are trying to cover when wall mounted cameras Any help would be appreciated
