Bests & Worsts Reviews from Amazon

I’ve installed many camera systems and I’m always looking for new products. I purchased system and installed on my own house to check the product out. Everything seemed flawless until I got errors on screen. I called Techsupport only to find out that they wanted a one time charge of 99$ to help. This is a brand new system and being charged for help is unacceptable. I’m sending the POS back.
