"We wanted to get on board with the current trend in doorbell cameras. Got a quote from ADT Provider, known as Safe Street USA, and felt their offer was more than fair. We have door sensors and motion detectors inside and the doorbell camera mounted outside. Nice to feel “with the times” in home automation and security."

"I had my storm door replaced by Byers security. Mike and Paul did a fantastic job installing it. They took their time and the door fits perfectly. Looks great. Mike was in touch with me throughout the purchasing process. Great company to deal with."

"Protect Your Home group with ADT has exceeding our expectations in getting a new home security system. In the end, everything was a breeze and not stressful whatsoever. We tested the siren and our neighbors 2 doors down could hear it; which is what we were hoping for!"

"I am leaving this review regarding Medallion Security Door and Window Company. In addition, as a customer I rate them with 5 stars. Why? First of all Medallion installed my back security door about 20 years ago, and I still use it, it's a little rusty now but that's due to my neglect. Second, I visited Medallion's show room in late June 2022. Erlin R. showed me around and provided just what I needed in terms of assistance, information and professionalism. Peter, came out a week or so later and measured my front entrance and on July 13th. 2022 Caesar and crew came out and installed front security door. I am satisfied 100%, plus I have received information on how to care for door which is a plus for my investment. THANKS MEDALLION & GOD BLESS. Sinclair H."

"I very much recommend this contractor! Answers fast, gives extremely fair prices, gives fast appointments AND the show up on time! They are very polite and nice. They also clean up the station after they’re done! I find them reliable, quality work and fairly priced. They also work as long as they need to. For our house they: Fixed the window frames outside because the mortar was broken or eroded and when it stormed outside, it rained inside our house. They changed rotten wood, painted it, cemented places in the brick wall that needed it, put mortar/caulk and sealed 4 windows from the outside. The other project was putting bifold closet doors which included cutting them to size, installing the hardware, and painting them. This was the first time I’ve had to hire someone to fix things around the house that I couldn’t, and I was really nervous. I’m grateful I found Chapin Handyman LLC through Angie’s list! Oh! And they are insured and bonded, too!"

Security Doors FAQs, answered by experts

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.

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.

In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.

It depends on your specific needs. A security system typically includes alarms, sensors for windows and doors , and 24/7 monitoring services, offering comprehensive protection with immediate response to potential threats. Cameras, on the other hand, primarily provide visual surveillance and evidence collection. A security system is preferable if your primary concern is deterring intruders and receiving real-time alerts. Cameras are ideal for monitoring and recording activities but might offer a different level of active protection. In many cases, a combination of both—a security system with integrated cameras—provides the most robust home security solution, offering prevention and documentation.

This is the topic of much debate, though there is no “better,” as it depends on personal preferences. Some of the components of a wireless system keep working when the power goes out, as they are battery-powered. On the other hand, a wireless system typically connects to your modem and router. Wired systems use landlines to communicate, which never go out on their own unless they’re physically cut.
