"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."

"Great. Mr. Chapman of Abstract LLC went above my expectations. He restored my old (2016) camera, DVR, and monitor security system. He purchased a new box (DVR), corrected a faulty camera hook up, and restored the pictures to the monitor. He installed an app on my cell phone so I can monitor activity around the house from anywhere I am. He also installed a Kami inside motion detector that I had been procrastinating about since 2023 and placed it on my cell phone. He is very knowledgeable about security systems and software programs"

"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."

Home Security Systems FAQs, answered by experts

While all security lighting systems offer different benefits, motion sensor security lights have the most advantages and the fewest cons for the average homeowner. While the upfront cost can be hefty, automatic, motion-detected activation will reduce your energy bills in the long run by ensuring the lights are only turned on when necessary. Plus, they’ll ward off intruders and help invited guests find their way onto your property in equal measure. 

While security hubs can streamline the management of security cameras, the placement of cameras itself is often determined by factors like your property layout, security objectives, and areas of concern.

When deciding whether a home automation system is right for you, consider the advantages and disadvantages first.

Pros

  • Home automation can help make your home more energy efficient, possibly lowering utility bills.

  • A wide range of automated solutions is available to meet your needs.

  • Centralized and remote control of different home automation systems.

Cons

  • Home automation can be costly.

  • Not all automated systems are compatible with each other.

  • Over-dependence on home automation can be problematic if systems cannot connect to the cloud.

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.

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.
