Brownsville’s Most Trusted Security & Fire Protection Company

Yes, in most cases you will need a permit for both burglary alarm systems and commercial fire alarm systems in Cameron County and surrounding municipalities. The exact requirements vary depending on your city — Brownsville, Harlingen, and McAllen each have their own alarm registration ordinances. The good news? Xtreme Security & Fire handles the permitting process for you. We know exactly what each jurisdiction requires, and we make sure your installation is fully code-compliant from day one.

Commercial fire alarm system costs vary depending on the size of your building, the number of devices required, and whether you need a new installation or an upgrade of an existing system. A small single-suite commercial space might start in the low thousands, while a multi-story building or large warehouse can be significantly more. Rather than guess, we'll perform a free on-site assessment and give you a transparent, itemized quote with no surprises. Financing is also available.

Absolutely. Xtreme Security & Fire holds all required Texas state licenses. We are licensed as a security contractor and alarm company by the Texas Department of Public Safety (DPS), and we are licensed as a fire alarm company by the Texas Department of Insurance / State Fire Marshal's Office. On top of that, our fire alarm technicians hold NICET Level II certification — one of the highest professional credentials in the fire alarm industry. You can verify our credentials at any time through the respective state agencies.

An unmonitored system sounds a siren when triggered but relies on someone nearby to hear it and call for help. A professionally monitored system connects to a 24/7 central monitoring station — when an alarm trips, trained operators are immediately notified and dispatch police, fire, or EMS on your behalf, even if you're asleep, out of town, or unable to respond. For most homes and virtually all commercial properties, professional monitoring is strongly recommended. Xtreme Security & Fire provides monitoring services through Alarm.com's professional monitoring network.

Yes — and it's one of our customers' favorite features. All Xtreme Security & Fire systems are integrated with the Alarm.com mobile platform, giving you live video access, real-time alerts, remote arming and disarming, door lock control, and a complete event history — all from your smartphone or tablet. Whether you're in McAllen, on a business trip in Houston, or relaxing on the beach at South Padre Island, you're always connected to your property.

Yes! While a large part of our work is commercial, we absolutely serve residential clients throughout Olmito and the Rio Grande Valley. We install professional HD surveillance camera systems for homes, apartments, ranches, and properties of all sizes. Residential camera systems come with the same quality equipment and Alarm.com mobile integration as our commercial installations — because your family deserves the same level of protection as any business.

We work with a wide range of commercial clients across South Texas. Our portfolio includes retail businesses, restaurants, medical and dental offices, warehouses and distribution centers, auto dealerships, schools and universities, churches, government facilities, and apartment complexes. If you run a business in the Rio Grande Valley and you need fire protection, security, surveillance, networking, or access control — we've probably done it before, and we can do it for you.

Access control is a system that uses electronic credentials — keycards, key fobs, PIN codes, or smartphone apps — instead of physical keys to manage who can enter specific areas of your building and when. If you've ever struggled with lost keys, unauthorized access, or just wanted to know who was in your building at any given time, access control is the answer. It's especially valuable for businesses with multiple employees, high-value inventory, sensitive records, or restricted areas. As a ProdataKey Gold Partner, we specialize in cloud-based access control systems that give you full control from any device.

For most residential installations, we can complete everything in a single day. Commercial installations depend on the size and complexity of your property — a small office may take one day, while a large warehouse or multi-building campus may require several days or a phased installation schedule. We'll give you a clear timeline during your free assessment so you know exactly what to expect and can plan accordingly. We work efficiently and cleanly, and we won't leave until everything is tested and you know how to use it.

Yes, we do! We understand that a quality security system is an investment, and we never want budget to be the reason a family or business goes unprotected. Xtreme Security & Fire offers flexible financing options for both residential and commercial clients. Our team will walk you through the available plans during your free consultation so you can find a payment structure that works for your situation. Call us at (956) 504-0811 to learn more.
