"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!

"I communicated with Rob Calbo for services of a background check with CSI Secure Solutions and he was fantastic.
He spoke with me in a very professional manner and put me at ease right away.
The process was seamless and my request was delivered very efficiently. Within just a few hours of providing them with information, I was able to get feedback. Rob took the time to speak with me and answered all of my questions. 
I will definitely be using them again in the future should the need arise, and I would definitely recommend them as being very efficient, professional and reliable.

Home Security Systems FAQs, answered by experts

Not all security systems are equal, so familiarize yourself with the many features available and any associated costs. Decide on a wireless or wired system and look at monthly subscription fees to access the service. Finally, read plenty of reviews to check out the efficacy of your intended security system.

While many security cameras rely on an internet connection to transmit footage and store it in the cloud, not all of them stop working when the Wi-Fi is off. Some models are designed to function offline by using local storage options, such as a microSD card or a network-attached storage (NAS) device. These cameras can continue to record footage even without an internet connection. You can then access the stored data once the Wi-Fi is restored.

It's recommended that you have an upload speed of at least 10 megabits per second (Mpbs) in order to use a wireless security camera.

Hiring a professional ensures optimal camera placement, secure installation, and integration with existing security systems. Professionals ensure reliable operation and can offer system customization to suit specific security needs or preferences.

Ultimately, the decision should align with your objectives. For general home security, visible cameras at entry points and high-traffic areas are recommended to deter intruders. In areas where privacy is a concern, use hidden cameras sparingly and within legal limits.
