We compared 18 home security systems in Philadelphia on Google Maps · 5 listed · How we rank

Buying a home security system in Philadelphia usually means choosing between a large alarm company with a monitoring contract and a local firm that installs and services what you own. The home security systems on this page hold more than 3,700 Google reviews between them, with ratings from 4.5 to a perfect 5.0, and the gap between the biggest review base and the smallest is wide enough to change how you read each score.

Short answer: SafeStreets has a 5.0 from more than 2,600 Google reviews, the largest review base on this page. Its site describes ADT-monitored systems. Vector Security (4.7, more than 500 reviews) has a Plymouth Meeting office, and Guardian Protection (4.5, more than 300 reviews) is based in Broomall. One SafeStreets reviewer mentions a plan covering three doors and nine windows for $69 a month on a three-year contract, so ask each company for contract length in writing.

How the scorecards work

Rating is the live Google star average. Review volume is how many customers have rated the business, compared with the others in this city. Confidence weighs the rating by that volume, so a 4.7 from hundreds of people counts for more than a 5.0 from a few dozen. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

What shapes the price of a home security system

Home security pricing in Philadelphia usually combines equipment, installation and a monitoring plan, often under a multi-year contract. A SafeStreets reviewer mentions $69 a month on a three-year contract for equipment covering three doors and nine windows. Door and window counts, cameras, add-ons such as speakers, and contract length all move the number, so ask each company for a written quote that separates equipment from monthly monitoring.

Where these companies work

SafeStreets serves Philadelphia homes as a service-area business, NoLimiTech is on North 3rd Street and Fidelity Burglar & Fire Alarm is in Somerton, in Northeast Philadelphia. Vector Security’s office is in Plymouth Meeting and Guardian Protection’s is in Broomall, both outside the city and both serving the Philadelphia area. Looking for a home security system near me? Each listing shows a phone number so you can ask who covers your neighborhood.

What to ask before signing a security contract

How long is the monitoring contract, and what does it cost to cancel early?
Who monitors the system, and is that a separate company?
Is the equipment included or leased, and who owns it if I move?
Which add-ons are optional, and who supports them after installation?
Is the quote in writing, with equipment and monthly monitoring listed separately?

Frequently asked questions

Who monitors a SafeStreets system in Philadelphia?

SafeStreets sells ADT-monitored systems and its site describes 24/7 monitoring. Reviewers mention ADT by name. Ask for the monitoring and contract terms in writing before you sign.

Are Vector and Guardian local Philadelphia companies?

Neither has an office in the city: Vector Security from Plymouth Meeting and Guardian Protection from Broomall.

Which of these companies installs cameras as well as alarms?

A Vector Security reviewer had five cameras installed, and NoLimiTech reviewers describe camera installs alongside networking and audio work. SafeStreets, Guardian and Fidelity reviewers describe alarm and security system work, so ask before assuming cameras are included.

Who explains how the system works after installation?

Vector Security reviewers say installers explained the purpose of each piece of equipment and trained them on the system, and SafeStreets reviewers say installers answered every question and showed them how to use it. Ask what training is included.

The short version

SafeStreets is the safe default for an ADT-monitored system, given the largest review base on this page. NoLimiTech suits a home that also needs networking or audio, and Fidelity is worth a call if you want a local alarm firm with yearly service reminders. Whoever you choose, get contract length and cancellation terms in writing.
