David from Delta arrived on time and was extremely efficient and business friendly. My finished basement provided logistical challenges but David assessed my request and came up with a way to ensure minimal wire visibility. He even suggested a 3rd camera placement that I am now glad that I did install. Delta was the only company whose wire layout would not leave wires along the basement floor or damage the drywall in my home. He actually went through the attic.
David took his time and the work was done within 4 hours. He also walked me through how to access the cameras and the dvr system.
My only caveat: ensure that you have a fairly new router and change your router and wifi password before Delta arrives. They will need your passwords and if you did what I did and mess up changing your password after the job is finished, then a revisit to update the system by Delta will be around $120.
All in all, I am very pleased with the work done by Delta through David.
