"Great experience with nighthawk! I purchased my own security cameras and needed help installing them. The technician was super knowledgeable, professional, and worked quickly. The job was done perfectly (and I’m sure it was a challenge - we live in a super old house!!). He made it seem easy! Highly recommend and will definitely be going to them for any future needs."

"We were with another monitoring company and Lloyd Security helped us throughout the transition and even sent the cancellation request for us. They made sure that careful attention was given to the aesthetics of the installation because we did not want wires to show or have extra holes drilled. They showed up when expected and completed the job the same day as promised. It's nice to deal with a business that is not only courteous, but prompt, careful and knowledgable."

Home Security Systems questions, answered by experts

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.

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

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.

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.

It depends on the type of sensor your home security system uses. If it’s a motion detector, any moving thing could set it off, from a roaming pet to a wind-blown curtain. Contact sensors would be triggered by the window being opened or moved. Also, be aware that any sensors placed too close to your vents could trigger false alarms whenever your heat or air conditioning is running.
