Video doorbells wired properly by Northgate Electric, with the transformer sized for the camera, the chime set up to ring, and your app connected before we leave.
A video doorbell looks like a five-minute swap. Take the old button off, connect two wires, pair it with your phone. In a lot of homes that is not how it goes. The low-voltage doorbell wiring in most houses was installed to ring a simple mechanical chime, and the transformer that powers it was never meant to run a camera, a speaker, night vision and a constant Wi-Fi connection. When a wired video doorbell does not get enough power, it drops offline, reboots in the middle of a clip, or leaves the indoor chime silent. Battery doorbells skip the wiring question, but cold weather drains their batteries faster, and a doorbell that needs charging every few weeks through a Colorado winter tends to end up dead on the porch. Northgate Electric installs wired and battery video doorbells across the Denver metro. We check the transformer and the chime first, replace or add whatever the camera needs, mount the doorbell level and at the right height for a clear view of faces and packages, and connect it to your app, so it works on day one and keeps working in January.
Most doorbell complaints we hear come back to power, signal or mounting. Call us if yours shows any of these:
Power is the most common cause. Video doorbell makers list a minimum transformer rating for each model, often 16 volts or more, while many older homes have a 10 volt transformer or one that has weakened after decades of service. A doorbell on an undersized transformer may seem fine at first, then drop out when night vision switches on or a cold snap hits. The chime can be part of the problem too. Some chimes need a small adapter so the doorbell receives steady power instead of a brief ring pulse, and some digital chimes are not compatible at all. Signal is the second cause. Front doors are often the farthest point in the house from the router, with brick, stucco or a metal storm door in the way, so a weak upload speed at the porch shows up as lag and missed clips. We check the signal at the exact spot where the doorbell will hang before we mount anything, and if it is weak we tell you what it will take to fix it.
The doorbell transformer is a small device that steps household power down to low voltage, and it can hide almost anywhere: on a junction box near the panel, beside the furnace, in the attic or inside a closet. The low-voltage side is simple, but the other side connects to a live 120 volt circuit, and that part of the job belongs to a licensed electrician. When the existing transformer is too small, we replace it with one rated for your doorbell and mount it properly on a junction box. When a home has no doorbell wiring at all, which happens in some condos and older homes, we can run new low-voltage cable to the door, or recommend a battery model if the wall construction makes wiring impractical. Old wiring gets a look too. Doorbell cable that has been nicked, stapled flat or spliced by a past owner can cause the same dropouts as a weak transformer, so we test the voltage at the door with the camera connected, not just at the transformer. The goal is a doorbell that stays online through summer heat and winter cold, and a chime you can hear from every room that matters.
A good doorbell view starts with height and angle. Most manufacturers suggest mounting around four feet off the ground, which catches the faces of adults and children without looking straight down at the top of a hat. When the door sits in a recessed entry or the walkway comes in from the side, an angled wedge mount turns the camera toward visitors and away from the street, which also cuts down on motion alerts from passing cars. Exterior walls change the method. Brick and stone need a masonry bit and proper anchors, stucco needs care so the finish does not crack around the hole, and lap siding often needs a flat mounting block so the doorbell sits flush and sheds water. We seal the wire penetration so snowmelt and wind-driven rain cannot follow the cable into the wall. Once it is mounted, we set motion zones to cover your step and walkway rather than the sidewalk or the house next door, which respects your neighbors’ privacy and keeps your phone quiet. In Highlands Ranch and other communities with active homeowners associations, covenants often cover exterior changes, so a quick check before mounting anything visible from the street is a sensible step, even though a doorbell rarely raises questions.

A video doorbell is often the first smart device on the front of the house, and it works best as part of a plan. Smart locks, porch lights that switch on when the doorbell senses motion, cameras over the garage and driveway, and a hub that ties everything together in one app all depend on reliable power and a strong signal. We wire and set up the whole system so each device does its job and talks to the others…
Those questions narrow the field quickly. A wired doorbell is the better choice wherever working wiring exists, because it never needs charging and wired models often unlock features that battery models limit to save power. An entry that faces the afternoon sun needs a camera with strong backlight handling, or visitors turn into silhouettes. Narrow door trim matters too, since some doorbells are wider than the frame beside the door and need a mounting plate. If you already have a smart home system, speakers or a smart lock, sticking with a compatible brand keeps everything in one app instead of three.
Subscription costs are worth weighing before you buy. Many doorbells save clips only with a monthly plan, while others store video on the device or on a home hub. Neither approach is wrong, but it is a cost that lasts much longer than the install. Tell us which doorbell you have in mind, or ask us to recommend one for your entry, and we will check the transformer rating, the chime and the signal at the door before the day of the install. If the doorbell needs a new transformer, a chime adapter or a signal extender, you hear about it up front, not while we are standing on your porch with the old button in hand. Call today to plan your doorbell install.
A doorbell camera that keeps dropping offline cannot show you who is at the door. If you are installing a new video doorbell, upgrading an old one, or fighting a doorbell that keeps losing power, Northgate Electric can sort out the transformer, the chime, the signal and the mounting in one visit. Call (720) 555-0142 to book, or request a quote online and tell us which model you have.
Straight answers to the questions homeowners ask us most about video doorbell installation.
All of the common ones, including models bought online or from a home improvement store. Tell us the make and model when you book so we can confirm the transformer rating and bring any chime adapter it needs.
The usual causes are a transformer that cannot supply enough power, a weak Wi-Fi signal at the door, or a damaged wire between the transformer and the button. We test all three instead of guessing.
The low-voltage side is simple, but the transformer connects to a 120 volt household circuit, usually at a junction box near the panel or furnace. That connection should be made by a licensed electrician.
We can run new low-voltage cable to the door and add a transformer, or you can use a battery doorbell. We look at the wall construction and tell you which is practical before we quote.
Often, yes. Many mechanical chimes work with video doorbells, sometimes with a small adapter installed inside the chime cover. Some digital chimes are not compatible and need replacing, or the doorbell can ring a plug-in chime instead.
A straightforward install on existing, working doorbell wiring typically runs about $125 to $300. A new transformer, new wiring or a chime replacement adds to that, and your final price is confirmed in writing after we look at the setup.
They work, but cold weather shortens battery life, so expect to charge more often from November through March. If your home has doorbell wiring, a wired model avoids the problem entirely.
