Nest's Cam IQ is the most advanced way to make your home safe, but of course that comes at a price.

It includes a speaker to communicate like using a web cam through the nest app. Its most advanced feature is its facial recognition, which is far beyond what the other cameras we tested could manage.

The average cost to have a four-camera surveillance system professionally installed is between $1,400-1,500. The range people pay for the entire system is much broader--between $700-$2,100--and varies according to how many cameras are being installed, the quality of the equipment, and whether it’s necessary to pay for a permit. Also, average costs vary by city. Wired systems cost more to install than wireless.
