Terrell Hills Home Security for a Town That Once Sued to Stay Itself

Terrell Hills is named for Frederick Terrell, a bank president who had served as mayor of San Antonio in 1901. Development started in 1919, when Terrell sold land to a private association, and the area was promoted as a residential addition through the late 1920s. Residents voted to incorporate in 1939. Six years later San Antonio tried to annex the young town without an election. Terrell Hills sued, and the court voided the annexation.

That lawsuit says a good deal about the local temperament, which prefers to manage its own affairs. The town adopted a home-rule charter in 1957 and grew quickly after the war, from 2,708 residents in 1950 to 5,572 in 1960. The 2020 Census counted 5,045 people in 1,850 households. The city sits about five miles northeast of downtown, bordered by Alamo Heights, Fort Sam Houston, and San Antonio.

Burglars who pry open back doors are rare in Terrell Hills. Six burglaries in 2024, by the FBI count. The more common visitor is the browser: someone who drifts down a street, checks car handles, eyes the porch, and leaves with whatever was easy. The city has put out its own reminder on this, a notice headed “lock it or lose it,” and the title is the whole sermon.

Browsers dislike being watched and recorded. A video doorbell covers the porch and lets you talk to a visitor from anywhere, which unsettles the ones with bad intentions and reassures the delivery driver. A camera aimed down the driveway covers the car. Our field guide to package theft and porch pirates lists the delivery habits that make a porch tempting and the simple ones that make it boring.

Nearly three-quarters of Terrell Hills households are families, by the 2020 count, and family houses tend to collect keyholders. The housekeeper, the lawn crew, the dog walker, the neighbor who waters plants in August, the teenager’s friend who once needed to grab something. Each copied key is a small act of trust that nobody remembers to revoke.

Smart locks end the guessing. Each person gets a code, each code can be limited to certain days and hours, and the app records who came in and when. When the lawn crew changes, you delete a code instead of calling a locksmith. The lock also relocks itself after a set interval, which covers the family member who never quite learned to turn the deadbolt.

The same logic applies to the garage, which in many homes is the real front door. A keypad on the outside and an opener that can be closed from a phone remove the most common lapse of all, the door left up after the kids biked to school. If you want, the garage can report to the alarm panel, so an open door at bedtime shows up as a reminder instead of an invitation.

A quiet street keeps an eye on itself, but it also notices patterns, and so does anyone casing it. Three days of dark windows, a full mailbox, and no car in the drive announce an empty house more clearly than a sign would. Smart home automation lets lamps, porch lights, and blinds keep a believable schedule while you are at the coast.

Winter is the other reason to stay connected while you travel. A hard freeze can split a pipe in an empty house and leave water running for days. Sensors near the water heater and under the sinks report a leak or a falling indoor temperature to your phone, and to the central station if you choose. Our write-up of lessons from Texas winter storms explains where to put them.

Terrell Hills households who call us get San Antonio Protection Services, a local company since 2010, licensed by the Texas DPS Private Security Bureau under license B16898. Terrell Hills is a few minutes from our technicians. On the visit we look at entries, sightlines from the street, lighting, and any system already on the wall, and we note which of those a passing opportunist would spot first.

Afterward you get a written plan in plain English. If it suits you, we install it, teach the household to use it, and connect it to 24/7 monitoring from a UL-listed central station. No pressure and no contract signed in the driveway. Start with a free security assessment.
