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!"

RC&G is an acronym - it stands for "Richard, Charlene, and the Girls", because it's a great reminder of what I'm working for. I'm Richard and my wife and daughters are the most important thing in the world to me. Also hugely important to me is doing great work in my business as a handyman. I've always been mechanically inclined and good at fixing whatever's broken. With decades of experience, now I'm truly a master handyman. Whatever you need, I'm here to get it done. I respond quickly to contacts and give an accurate estimate. Then I arrive as scheduled, do the job right, and leave your house as clean as I found it. I'm looking forward to meeting you!

"Project went fine. Richard was very professional and accommodating!"

FAQs for alarm or security system installation projects in Brentwood, CA

If you terminate your security system before your contract ends, you’ll likely have to pay a cancellation fee—often a percentage of the remaining contract balance. To avoid these fees, consider choosing a brand that offers contract-free plans, like SimpliSafe or Vivint. You can also negotiate with your provider to see if they provide pro-rated cancellation fees or special exceptions.

Paying for a security system is a valuable investment because it enhances your home’s safety and deters criminal activity. With millions of property crimes each year, having robust security measures helps protect your property and might even lower your insurance premiums. It's a worthwhile investment for lasting peace of mind.

The average cost to install security cameras ranges from $125 to $3,500, depending on the amount, type, and placement. To install a complete setup of four cameras, homeowners can expect to invest an average of $1,300 for labor and equipment. Installing multiple cameras gives you comprehensive coverage of vulnerable entry points and enhances overall property security.
