"Last weekend had someone pry our side door open to our exterior garage and the ADT door sensor picked it up immediately. The alarm siren was loud and scared the person off. Someone from the response center called within 30 seconds. We’re fortunate that the security system did what it is supposed to. Feels like we made the right call going with an ADT security system."

"Rafael was great - he fixed our front door knob and lock, replaced another door handle, and our towel bar. He worked us into his busy schedule and came by on a day that was best for me. Rafael picked up parts he needed at Home Depot after assessing what we needed, and efficiently completed all three jobs."

"Great company! I needed to replace my regular door and security door. Valentino (the owner) had come by for a free assessment and estimate. He provided a fair assessment without being pushy which I greatly appreciated. The doors were custom made according to the specifications I had chosen. The crew that came by to do the installation were friendly, professional and were respectful of my property. As part of the installation of the doors, they also had to do new jambs and the bottom (I previously had a half step). The end result is absolutely beautiful and I am so happy with my new doors. They are well sealed when closed and I no longer have a draft. I highly recommend Custom Windows & Doors!!"

"Install was easy. Up front cost was pretty low with Angie's List coupon. Monthly price is a little high compared to competing companies. Response time with alarms is excellent. I was advised to use glass break alarms within 10 ft of my first floor windows, which we installed correctly. I asked prior to installation if having one in the kitchen would cause false alarms due to dishes clanging, etc. I was told the glass break alarms are configured to a precise frequency that alarms with breaking glass. So, not a "no", but not really an answer. Well, every time we cook dinner, wash dishes or empty the dish washer, the kitchen glass break alarm gives a warning which would sound the alarm if it was set. This has caused us a number of false alarms while we've been away due to shifting bowls or plates in our drying rack. For the first several we've had to pay our police department $120 to check the house, and I was only notified after the first alarm that there was a cheaper option for a security company to drive by to check for a break in."

Security Doors FAQs, answered by experts

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 benefit of deadbolt locks is that they're much harder to force open than simple locks with pin tumbler mechanisms, so they may offer added security. This feature is why many locksmiths recommend deadbolts for home security. For many households, this added protection and peace of mind is well worth the cost of installing a deadbolt.

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).

Expect to spend an average of $150 to $500 to set up a home flood detection system. However, be aware that costs are wide-ranging. You might only spend a budget-friendly $50 to place basic, battery-operated sensors in a few key areas of your home, or $150 to set up two or three smart sensors. The purchase and professional installation of a whole-home protection system with water shutoff capabilities could cost between $500 and $1,000.

While security hubs can streamline the management of security cameras, the placement of cameras itself is often determined by factors like your property layout, security objectives, and areas of concern.
