That is unless you don’t have an existing doorbell, in which case we recommend you hire an electrician. However, if you don’t have an existing doorbell and you want to buy a hardwired doorbell camera, you will probably need to hire an electrician to do the installation for you. Because if there is no existing doorbell wiring present, your new doorbell camera will need to be completed wired with new wiring. So unless you are an electrician, or have significant electrical skills, you probably should not attempt to do this type of installation yourself. Because not only could it be dangerous, it could also turn into a fire hazard if it is not done right. Electricity is not something you want to take any chances with.
