Was recommended by a good friend. Quoted $2400 for 4 cameras. 3 wirelss, one wired. The wired one works great. Wireless dont work. Had someone else come in. To check his work. Second said his work and cameras are good. Problem is that the router is not strong enough. So we put in a booster. System needed a reboot. Once reboot happened, it asked for a password. I called the , whom offered 3 years warranty, I asked for password to the wireless cameras. Guessed some answers. And started yelling.
