The doorbell camera is your most-used security device. Install it like it matters.
There is a particular species of frustration reserved for the homeowner who mounts a video doorbell himself, discovers the chime transformer is 8 volts, and spends the next three weekends learning more about low-voltage wiring than he ever wanted to know.

The transformer is the whole story
Most homes in San Antonio built before 1995 have a doorbell transformer rated at 8 to 10 volts and a fraction of the amperage a modern video doorbell wants. The device will power on. It will even work, for a while. Then it starts rebooting during recordings, dropping the last four seconds of every clip — which, by a cruel law of the universe, is the part containing the face.
We test the transformer before we mount anything. If it is undersized we replace it, which takes about thirty minutes and requires knowing which breaker feeds a 16-volt transformer stapled to a joist in an attic that hits 140 degrees in July. That is a fair description of why people hire this out.
Angle, chime and the package problem
A doorbell mounted at standard height on a narrow porch column sees a chest and a chin. We use wedge and angle mounts to correct the field of view so it captures a face on approach and, just as importantly, captures the porch floor where packages land. If your front door sits back under a deep overhang — common on Spanish Colonial and ranch homes across the older parts of town — the default aim is almost always wrong.
We also make the indoor chime work. Not a phone notification you will miss because you left the ringer on silent. An actual chime, plus optional announcement through the alarm panel, so somebody standing at your door registers in the physical world.
Integrated, not orphaned
A doorbell that lives in its own app, with its own login, next to the four other security apps on your phone, is a small daily tax on your attention. We integrate the doorbell into the same platform as your alarm and cameras, so one app shows you the front door, the driveway, the back patio and whether the system is armed.
We install and service Ring, plus Alarm.com and Qolsys doorbell cameras. If you already own a Ring and just want it hung correctly and wired to a proper transformer, that is a legitimate service call and we are happy to do exactly that and nothing more.

Questions people actually ask
- Can you install a doorbell I already bought? +
- Yes. We install customer-supplied Ring and Nest doorbells regularly. We test the transformer, correct the mounting angle, and configure the app before we leave.
- My house has no doorbell wiring at all. Now what? +
- We either pull new low-voltage wire from the nearest accessible junction or install a battery unit with a plug-in chime. We will tell you which is realistic for your construction before you commit.
- Does the doorbell work with my alarm system? +
- If your panel is Alarm.com-powered, yes — doorbell events appear in the same timeline as alarm events, and you can trigger the doorbell camera to record when the system disarms.
