"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

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.

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. 

A steel door that's been toughened up with extra materials creates the perfect barrier. These bad boys are way stronger than your typical wooden or fiberglass doors, making them a fantastic choice for folks who want that extra layer of security for their homes. So, if you're all about keeping things super secure, a reinforced steel door will cost you more, but it is your best bet.

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.

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.
