ADT home security systems are backed by more than 145 years of experience. As the leader in home security, ADT can help you customize a home security system with easy-to-use equipment and special security features to meet your safety needs. 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!"

We are a locally owned and operated security company that values honesty and integrity in all aspects of our business. Our major focus is on providing quality work and producing outstanding results. We are committed to creating a level of value unmatched by any of our competitors. We look forward to building lasting relationships with our clients and guarantee your satisfaction!

"It appears this company engages in misleading sales tactics to trap customers into automatic yearly contract renewals. As many other Google reviewers have pointed out, they never clearly explain that the contract renews automatically each year. If you want to cancel, you're required to do so in writing, 30 days before the renewal dateâ otherwise, you're locked into another year of service. While we were remodeling our home, I tried to cancel the service by phone. However, Christian offered to pause the contract for six months, which seemed helpful at the time. In hindsight, itâ s clear this was just a tactic to keep us tied to the contract. Despite numerous conversations with Christian, he never once mentioned the critical details about how to properly cancel or the automatic renewal process. After over two years of not using the service, I called to officially cancel, only to be informed that I still had six months remaining on the contract. This lack of transparency and the constant hurdles to canceling the service are extremely frustrating. I would caution anyone considering this company to be aware of these practices."

FAQs for home security system service projects in Terrell Hills, 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 locks: $150

  • Smart home lighting: $15–$90

  • Smart smoke, fire, and carbon monoxide alarms: $35–$100

  • Smart thermostat: $130–$500

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
