The price of installing cameras is related with the type of the project, it varies if you to install home security cameras outdoor, in door, or if your project is to install cameras in a warehouse of front store.
The big factor that make the price to vary though is not the location to run the wiring of your cameras, but the CCTV Company you deal with.
Many independent "Camera Installers" are not licensed or registered with the DBPR, don't have a registered company, and don't even have insurance, hence they work "cheaper".
If you work with a registered, licensed and insured company, the labor to install hardwired and configured security cameras may range from from $80 to $200, depending on the complexity of the project.
