We have service centers nationwide that can install an ADT home security system within 24 hours in most areas. Once your home is equipped with our top-of-the-line system, it is connected to a network of ADT Monitoring Centers nationwide which deliver non-stop security monitoring 365 days a year. All of our installation technicians are internal employees, and not third-party contractors. You can count on your Security Advisor to take the time to set up your system properly, help you understand how the system works, and help make sure your home and family are thoroughly protected.
"I've been using ADT Home Security for over a year now, and it’s been worth every penny. The peace of mind it gives my family is priceless, but the cost is surprisingly reasonable—just $99.99/month for the Smart Home package. The installation was quick and professional, and the technician took time to explain everything. I love being able to control the system from my phone, and the instant alerts are super reliable. The customer service has also been excellent whenever I had questions. With 24/7 monitoring and smart home integration, I truly feel my home is protected at all times. I highly recommend ADT to anyone looking for a trustworthy and advanced security system. Five stars without hesitation!"

"Vivint is the worst company I have ever done business with. Having Vivint is a condition on my lease and, if it wasn't, I would quit in a minute. The company is so cheap about replacing malfunctioning equipment. My front door lock doesn't work and I have been working on getting a replacement for over a month. Still no luck. An appointment is not an appointment but I rough guideline to when someone may or may not show up. There are a lot of alarm companies and I could never recommend Vivint."

FAQs for home security system service projects in Harlingen, TX
The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:
Video surveillance monitoring: $40–$65 per month

Smart home lighting: $15–$90

Yes, a home security system can be worth it for your peace of mind alone, but it can also save you up to 20% on your home insurance. The insurance savings will help defray the initial setup costs and subscription costs over time. Locations with higher crime rates also make home security systems a valuable investment, but it ultimately depends on your personal preferences and asset values.
With the popularity of DIY security cameras and video surveillance systems, it’s important to understand the benefits and potential drawbacks to decide if it’s the right choice for you. Advantages and disadvantages include:
Pros
Video footage readily available
Reduced home insurance
Save on labor costs by installing security cameras yourself
Wireless systems are easy to move and set up
Monitor from your smartphone
Avoid false alarms
Cons
Features may be vulnerable to hackers
No direct link to authorities
Risk of installing the system improperly, reducing its effectiveness
Whether a security system or security cameras is a better choice for you depends on your needs and preferred comfort level. A security system can cost more depending on the features you choose, but it’s a more proactive and protective approach to home security by alerting you and authorities of any emergencies. Using a security camera system is a more reactive approach because while you can monitor the camera footage, it does not alert the proper authorities for you.
Understanding the pros and cons of installing a home security system is the first step to deciding which one is right for you. A few of the advantages and disadvantages include:
Pros
Added security for your household
Reduced home insurance premiums
Many smart home integrations available
Security companies can monitor your home
Cons
Expensive setup costs
Subscription costs can add up quickly
Features may be vulnerable to hackers
Weak signal reduces the security of a wireless system
