"I used to work in the security industry. Once I got married and had kids I definitely wanted a home security system. Bought ADT about a month ago and it’s worked out excellent. No glitches or issues and everyone was awesome in the buying and activation process."

I was a corporate field engineer for over 30 years, I worked for 1 company only, I built it from the scratch with the business owner. I did pretty much everything from accounting to all the way physically building commercial stores. My nickname is "Mr. Fix." Lol. Whenever there is something to be fixed, that was my job. It could be fixing a towel, or plumbing, or business strategies...etc.

"They gave us the best rate and the setup was great for ADT system. The installer did have to tell us about other options that would cost more money but he did not pressure us when we declined. We had door, window and motion detectors included. They gave us a week to practice on the new system, but we could call if we were ready to go live sooner which we did. Set up was quick, easy and uneventful. Very nice installer, Phillip Brown. The cost was quoted at a low price, but the bill came from ADT and was much higher. We were told the contract to ADT did not catch up and we will be getting the lower price with a reimbursement for the excess of the first bill. We did the $99 install and are getting a $100 gift card back. 3 year contract is a little annoying but we plan to stay here for a long time."

Home Security Systems FAQs, answered by experts

You don’t need to completely revamp your security system constantly, but it’s a great idea to give it a once-over every year. Look for potential upgrades or new features—like smart home tech or replacing outdated equipment—that could boost your safety. If you make any significant changes, let your insurer know as they may adjust your discounts to reflect your improved security. Staying on top of your security not only keeps your home safe but ensures you’re getting the best possible rate on your insurance.

One significant drawback of home automation is the increased risk of cybersecurity threats. With more connected devices in our homes, there's a greater chance that hackers might try to exploit vulnerabilities to access personal data or even control your devices. If you don't secure your smart gadgets properly, they can become entry points for cyberattacks, risking your privacy and safety. Moreover, technology isn't perfect. Sometimes, systems can malfunction or experience connectivity issues, disrupting your daily routines. The upfront cost of buying and installing smart devices can also be a hurdle for some people. 

The average cost to install a home security system is about $750. However, the price can range from as little as $200 for a simple wireless camera setup to $2,000 for a fully monitored, hardwired system. A typical price range is $280 to $1,150. Several factors determine the final cost, including the type of system, equipment, materials, labor, activation fees, monthly surveillance fees, and permits. Optional upgrades will also add to the price, such as video surveillance monitoring ($40–$65 per month), smart locks ($150), smart lighting ($15–$90), smart smoke and carbon monoxide alarms ($35–$100), and a smart thermostat ($130–$500).

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.

You likely can reset your house alarm without the code, but it depends on many factors like how it’s wired and whether or not there’s a default reset code. Most companies make bypassing a security alarm without entering your code challenging to prevent burglars from simply resetting the alarm during a break-in. Your best bet is to contact your alarm company directly to get specialized support for your situation. 

But, while you wait for support, you can disconnect it from the power source to stop the alarm from going off.
