So, unless you are familiar with how electrical wiring works, you should probably hire someone to install it for you. However, with that being said, many doorbell camera systems come with help videos and technical support that could guide you through the process if you feel like attempting it yourself. 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.
