Quick Answer

6 min — here's the short version

If you have existing doorbell wiring and are comfortable with basic electrical work, you can likely install a video doorbell yourself. However, if you need to upgrade your transformer or run new wiring, we recommend hiring a qualified electrician from PEKC.

How Video Doorbells Enhance Home Security

A video doorbell allows you to see and speak to visitors at your front door, whether you're at home or away. This can help you screen visitors, prevent package theft, and deter potential intruders. Many video doorbells also include motion detection, which will send you an alert on your smartphone when someone approaches your door. In a city like Pittsburgh, where package theft can be a concern, a video doorbell provides an extra layer of security and peace of mind. It's a small investment that can make a big difference in protecting your home and family.

Understanding Video Doorbell Power Options

Video doorbells can be powered in two ways: by a battery or by being hardwired into your home's existing doorbell wiring. Battery-powered doorbells are easier to install, but they require periodic recharging. Hardwired doorbells receive continuous power, so you never have to worry about the battery dying. Most hardwired video doorbells are designed to work with a standard 16-24V AC doorbell transformer. Before you purchase a video doorbell, it's essential to check the voltage of your existing doorbell system. If your transformer is not powerful enough, you'll need to have it replaced by a qualified electrician. At PEKC, we can inspect your doorbell wiring and upgrade your transformer if necessary.

Installing a Hardwired Video Doorbell

Installing a hardwired video doorbell is a relatively straightforward process for most homeowners. Start by turning off the power to your doorbell at the circuit breaker. Then, remove your existing doorbell button and disconnect the two wires. Attach the wires to the terminals on the back of the video doorbell mounting bracket. Mount the bracket to the wall, and then attach the video doorbell to the bracket. Once the doorbell is installed, turn the power back on at the circuit breaker. The doorbell will power on, and you can then follow the manufacturer's instructions to connect it to your Wi-Fi network and configure the settings in the app.

What to Do If You Don't Have Existing Doorbell Wiring

If your home does not have existing doorbell wiring, you can still install a hardwired video doorbell. A qualified electrician can run the necessary wiring from a nearby power source to your front door. This will involve drilling a small hole through the wall and running a low-voltage wire to the doorbell location. The electrician will also need to install a new transformer to power the doorbell. While this is a more involved installation, it provides the reliability and convenience of a hardwired video doorbell. If you live in the Pittsburgh area, the experts at PEKC can provide a professional and affordable installation.
