Conventional doorbells are great for budget-conscious homeowners and those who appreciate simplicity. But even though they aren't very complicated, most conventional doorbells eventually fail -- mechanical models last about 10 years, and electronic models only work for half as long. Replacing either type does entail some safety risks, so it’s generally best to hire licensed electricians to carry out the work.

Modern video doorbells obviously make life more convenient, but they also offer increased home security and give you the chance to record people who approach your front door. But installing video doorbells can be tricky – they present all of the safety issues that conventional doorbells do, and they also present configuration challenges. This means that professional installation is recommended.

Most modern video doorbells can be connected to your phone, computer, or smart home system, allowing you to speak with visitors (even if you’re not home). Many video doorbells can also be integrated with your other systems, including security lighting, alarms, and electronic door locks. A licensed electrician can help not only install a video doorbell but also connect it to your other systems.

One of the most overlooked advantages of modern digital and video doorbells is the ability to customize the way they function. For example, you can often change the type of chime the bell triggers, as well as its volume level and duration. Many models also feature different colored LED lights, and some allow you to set up multiple user accounts, with varying permissions and capabilities.
