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!"

"DO NOT USE THIS COMPANY. Please look at the YELP or BBB complaints, they are much more akin to what I experienced. They are certainly manipulating the Google reviews. I hired Lion to do a simple cleaning/certifying of our HVAC units as part of a sale. I was initially quoted $119, and I verified no less than 3 times with the customer service rep that the price would include cleaning and testing. When our tech showed up, he said we were misquoted and the charge for cleaning and testing would be about $450, as it was part of their "maintenance" package. They very reluctantly cut us a "deal" for just over $300. Not only was zero cleaning done, the tech did not perform a single action that could be classified as "maintenance." What we got was a diagnostic and estimate for repairs and replacement. I called to complain twice before someone finally got back to me. I was told that the tech didn't perform the cleaning because it may have damaged the unit, which was clearly a lie because the tech never told me that and actually gave me a quote to perform the AC coil cleaning, $470 (what a deal!). The rep then told me that a simple cleaning was done, but not the deep clean that I was expecting. I asked that my invoice be revised to reflect that, but was quickly blocked. Yes, they actually blocked my number after repeatedly misrepresenting both the price and work. I was shocked. I filed a complaint with the BBB, of which I discovered there are many. Hopefully they do the right thing and just give me a refund, but I won't hold my breath. Again, they are clearly manipulating their reviews on Google. Customers do your research!"

FAQs for home security system service projects in Denver, CO
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

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
