"SafeStreets’ alarm system is fantastic. The motion sensors, door/window contacts, and cameras work flawlessly. The home automation features are a huge plus—I can control everything from my phone. Highly recommend SafeStreets to anyone looking for reliable security."

"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."

"SECURITY WINDOWS AND DOORS: I have spent a LOT of money putting in security windows and door as my home has been broken into many times while Charlie was here. I have had 2 companies, a local was fantastic but expensive yet worth it. They can no longer find someone to make security windows After contacting others who stopped calling (Medallion) when the 3 window job looked not worth the effort, I found Michael Byers on HOMEADVISOR/Angie's List. It is in Gaithersburg; he came right away to measure my windows; he special made one window for the cats so they can get their fat butts through. Windows are usually about $650 each but he charged $1000 for 3 windows and installation -- and they are the fancy windows. I was shocked and they were installed within a week. He has a factory where he makes the doors and windows himself. My HD door lacks were awful. On 3 doors, he installed new deadbolt and handle locks for a little over $200 -- including installation. The doors lock wonderfully and I have the same key for all of the locks. His number is 301-252-5117. With so many break-ins in my area, security windows and doors are now affordable."

"Have used Joe 3 times now. First to replace 4 exterior doors. Second to refinish some interior paint and trim. Lastly for a complete kitchen remodel. Each and every time he was prompt and very professional with great attention to detail. He has a permanent place in my address book and will certainly be called on again, probably sooner than later."

"Terrific, we decided to go w/ Stoneberger because their sales representative spent time advising and guiding us through the options, the colors and styles of doors. She listened to what we thought we wanted and helped us find the right solution. No other sales rep we met with offered that customer service. She also followed up on time and was super easy to work with once we decided on specific doors. Installation also was on time, efficient and went very smoothly. We had one issue that arose b/c of the age of our house and Stoneberger addressed it quickly and beyond fairly. Highly recommend them."

Security Doors FAQs, answered by experts

It's recommended that you have an upload speed of at least 10 megabits per second (Mpbs) in order to use a wireless security camera.

Smart deadbolts are a worthwhile investment for homeowners seeking more convenience, flexibility, and advanced features than a traditional deadbolt can provide. While a strong conventional deadbolt offers sufficient security for most, smart deadbolts provide significant upgrades.

Key benefits include keyless entry via smartphone, keypads, or biometric sensors, and the ability to lock or unlock your door remotely. You can also manage access for guests by creating temporary codes, eliminating the need for physical keys and the risk of them being lost or duplicated. Many models integrate with smart home systems and offer features like automatic locking, entry-exit monitoring, and tamper alerts with encryption for enhanced security.

However, there are downsides to consider. Smart deadbolts are more expensive than their traditional counterparts and rely on batteries and wireless networks to function. This dependency introduces potential vulnerabilities, such as hacking by skilled intruders and privacy concerns. Installation can also be more complex. Despite these drawbacks, the added layer of convenience and protection makes them a compelling option for many.

The main difference between different security sensor options is the type of motion each detects. A motion detector monitors obvious movements in hallways, entrances, and exits. On the other hand, a presence detector is more sensitive and captures smaller moves. A window sensor typically focuses on the opening and closing of the window, whereas a glass break sensor alarms you when a glass is broken.

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).

Costs depend on system type, labor rates, and additional features like smart integration or professional monitoring.
