"The owner of Electronics 9-1-1 installed an eight-camera home security system in my home. The entire experience, from initial consultation to finished product, was the model on which all other advertisers' services on Homeadvisor should be based! The company owner's recommendations about installation techniques, technical knowledge and considerations, equipment capabilities, scheduling accommodations, and modifications in mid-installation to overcome unforeseen issues were all spot-on, and resulted in a system that exceeded every expectation. Would use Electronics 9-1-1 again in a heartbeat, and it is a pleasure to recommend them to anyone needing security system installation or service of the highest quality."

"All processes are coordinated by the owner ( Marco). He is responsive, professional, expert in his field, transparent, has competitive pricing, uses the most advanced systems, and customer oriented. Marco personally makes sure all aspects of the security system (sensors/cameras/monitoring/applications) are working seamlessly before project completion. He was a pleasure to work with and his associates were top notch."

"It went great!  From Travis the sales person to Noah the installer I couldn't have asked for a more professional and through team to deliver my home security needs.  We just bought a new house in a neighborhood that's up and coming but there's still an element that we want to protect our home and valuable from.  Security One helped us find a system that we could monitor while we're away and that would make my girlfriend feel safe when I'm not a home.  We highly recommend them especially Travis and Noah.  Ask for them by name!

Home Security Systems FAQs, answered by experts

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.

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.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

You should always install cameras at exterior doors and windows. Other areas where you should place cameras are your front and back yards, the garage and driveway, common living areas, hallways and staircases, and the basement. Remember, you can start with a small Wi-Fi security camera system and always add more cameras if needed.

Strike plates and security plates are the same thing, but there are strike plates that offer more security than others. For the highest security, look for plates made of heavy-duty steel, reinforced strike plates thicker than regular ones, and extended strike plates. It’s much harder to break into a door with these strike plates because they hold up better to force from attempted entry.
