"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

Changing the alarm in your wireless security system is a perfectly reasonable DIY task that most people can complete on their own. Simply open the system’s control panel, remove the existing battery, and replace it with a new one. If you’re using a wired system, this may require disconnecting and reconnecting both the positive and negative wires attached to the battery, and you may want to call in a professional to help. 

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. 

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.

Technically, there isn't a difference between safe rooms and storm shelters. Both are designed to protect you from storms and extreme weather events. People often use “safe room” when discussing a shelter inside a building and storm shelter when talking about a detached unit. 

Additionally, a safe room is understood to have more functions than a storm shelter. You may seek shelter in a safe room when you believe an intruder is in the home or when under another type of threat. 

Yes, there are, and they often come with a screw set to ensure they stay secure. They run on batteries, depend on WiFi, and often require a WiFi extender. These typically cost less than $50. Doorbell cameras like these are great for renters who can't install a wired solution. However, a wired doorbell camera is a better choice for homeowners looking to invest wisely in home security.
