First of all, read EVERYTHING to the letter they make you sign. I was tricked into a 3 year maintenance contract that I was unaware of until I was having problems and wanted out. They took my old cameras down that I only replaced for better quality HD ones. They then installed low resolution junk cameras. Put 2 in out of eight then left me for months without cameras. After more months of arguing and phone tag, I finally got my cameras 1 year later, but they were not working correctly. They did not comply with their part of the contract but yet I still had to pay. In the end they finally got their payment over 1.5 years after the initial install date. I still don't have cameras that function properly. They do not come to fix it like in the contract. When it was all done I had to pay to get out of the contract, $2000+. I do not recommend using this company due to my long and horrible experience with them.
