"I used to work in the security industry. Once I got married and had kids I definitely wanted a home security system. Bought ADT about a month ago and it’s worked out excellent. No glitches or issues and everyone was awesome in the buying and activation process."

"I would not hesitate to recommend MSI to anyone needing to have security cameras or alarms installed in their home. They always arrived at the time that was specified which was 0830. On their first attempt to install the cameras it was raining profusely but they tried to install them anyway. However, at one point it became to dangerous and they had to stop and reschedule the installment. Nigel Frazier and his team are very professional and knowledgeable about the security system that they install. I'm very pleased with their professionalism and reliability."

"I had issues with 2 lights and circuit breaker in my home and JA Electrical were a godsend. I heard back from them within minutes of placing online quotes in my area. I was able to get a tech, Antonio, out to my home the same day. He worked ho*** ** getting my issue resolved and he succeeded. He's very professional, timely, and I would highly recommend him and the company to anyone having issues."

Home Security Systems FAQs, answered by experts

There is no “better” option, as it depends on your personal preferences and home’s needs. Wireless systems are much easier to install, making them DIY-friendly. Wired systems offer a more reliable connection that is not tied to a router, but they typically require professional installation.

Leaving a light on at night probably does not deter burglars as much as we would like. While there isn’t much evidence supporting the theory that lights deter burglars, there’s not anything disproving it either. If you feel like it offers added security because a burglar thinks you’re at home, then you can set your lights to a timer so they go off and on at intervals, mimicking someone moving around inside the house at night. A better idea is to install motion sensor lights in your yard.

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. 

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.

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.
