Thanks Nat23! We will look at this brand. Does anyone have a ballpark estimate on how long it would take to install 8 or 9 cameras with DVR, on/in a house with concrete block construction? And I mean the house is entirely concrete. Roof, eaves, etc. we would need to put cameras on overhangs and sides of outside walls. (Typical Italian construction) We were going to explore hiring a local electrician, but want to ensure the labor costs were reasonable.
