I don’t mind admitting that I was glad of the professional installation for my Vivint Security system. I’m just not a DIY type. I would say that you should be aware that the installer might try to talk you into more equipment than you planned on, and the price on the up sell might be more than you anticipate. If you go into installation with a firm idea of what you want, though, it’s a smooth process. Nobody was messing with the wiring in my walls or making holes in the house, thanks to the wireless technology their equipment uses. All in all, I’m feeling well set up.
