about us


Sierra Security started in 1986 in the city of Sierra Vista, AZ. Our goal was to provide our customers with the latest state of the art security equipment and
protection services available. To this day, we remain dedicated to giving our
customers quality service and reliable security products.


Although we are currently based out of St George, UT, we cover the states of Montana, Utah and Arizona. Let us show you how your life can be simplified by taking care of some of the worries and concerns that may be troubling you. Let our security systems provide you and your family with peace of mind and freedom from any nagging anxieties that your home or business may not be protected.
At Sierra Security, we treat our customers like family. Unlike other companies, we won’t trick you into signing a multiyear contract or falsely promise you a “free” system. We don’t require contracts, and we will take care of you from beginning to end. Call us today for more information!



Our 24-hour monitoring service guarantees fast response. We can monitor all makes and models of security and fire alarm systems without requiring a contract. Our philosophy is, “If you’re not happy with our service, you shouldn’t be forced to stay with us.”


Consult with our engineers about your security, fire alarm or CCTV system. With our engineering expertise, we are qualified and happy to answer any questions or address any concerns you may have about getting your systems into operation.


Are you building a new home or business? You can save a lot of hassle by planning ahead for your security, fire, CCTV and access control systems. Pre-wiring will allow your system to be installed in the least conspicuous way. It can also provide the most secure method of protection. A couple of hours of pre-wiring can save quite a few hours down the road.


Allow us to maintain your system. We can service all makes and models of security and fire alarm systems. We can also adjust/focus your cameras and repair broken or non-functioning equipment. We currently hold a master electrician license, fire alarm license, and low voltage/security license. We can take care of all your electrical, security, fire alarm and camera system maintenance and repair needs.
