Sting Alarm vs ADT, Vivint, and SimpliSafe
An honest comparison of Sting Alarm and the big national home security brands: who installs, who services your system, contracts, and monitoring, side by side.
Searching for home security in Las Vegas puts three national names in front of you: ADT, Vivint, and SimpliSafe. All three are real companies with real products. The difference is the model: national brands built to serve millions of accounts, or a local company built to serve this valley. Here is the side-by-side, with the facts drawn from each company's own website and filings.

Where each one fits
SimpliSafe fits renters and tight budgets: you install it yourself, there is no contract, and you get what a self-installed kit can give. The tradeoff is permanent: there is no local office and no technician coming to your house, because you are the technician.
Vivint is a smart-home-first system with professional installation and polished equipment. Most customers finance the equipment, and financing terms run up to 60 months, so read the total cost across the full term before comparing.
ADT is the oldest brand in the industry with national reach. Depending on where you are and how you buy, your install and service may come from ADT itself or from an authorized dealer, so ask who will actually show up at your door.
Sting Alarm is the local option: designed, installed, monitored, and serviced by one Las Vegas company that has been here since 2003.
Why Las Vegas homeowners choose the local company
The person who installs it answers for it. Our technicians are the people in the team photos on this site, not a dealer network. When you need service, the truck that shows up says Sting Alarm, and the office it came from is on Rafael Ridge Way.
Video verification gets a response. Police in Southern Nevada prioritize verified alarms. We tied cameras into alarm monitoring early, so our operators can confirm what is happening and request dispatch with facts in hand.
One company for everything, including fire. Alarm, cameras, smart home control, and, for business owners, licensed fire protection. One number to call, and over 1,000 five-star Google reviews behind it.
Straight answers on the agreement. We require a 3-year monitoring agreement and we say so here, in plain text, before you ever talk to a salesperson. Compare that with any teaser rate: ask what the term is, what the early termination costs, and what the price is in month 25.
Questions to ask any alarm company
- Who installs my system: your employees or a dealer?
- Who comes to my house when something breaks, and how fast?
- What is the full agreement term, and what does canceling early cost?
- Where is my alarm monitored, and is the center UL-listed?
- Can your monitoring operators see video to verify an alarm before requesting dispatch?
We will answer all five in writing. Request a free quote or call (702) 737-8464 in Las Vegas and (602) 431-1300 in Phoenix, and put us side by side with any national brand.

Over 1,000 five-star Google reviewsFrequently asked questions
Is Sting Alarm cheaper than ADT or Vivint?
It depends on the system, which is the honest answer. We quote real equipment and monitoring pricing for your home up front, so you can compare line by line instead of guessing from a teaser rate. Request a free quote and put our number next to theirs.
Can Sting Alarm take over my existing ADT, Vivint, or other alarm system?
Often, yes. Some national-brand panels are proprietary, but sensors and wiring can frequently be reused. We evaluate what you have, tell you what can stay, and quote the takeover before you commit.
Does Sting Alarm require a contract?
Yes. Monitored systems require a 3-year monitoring agreement, and we explain the agreement clearly before you sign. We would rather tell you that plainly than surprise you on page nine.
Is DIY home security good enough?
A self-installed system is better than no system, and for renters on a tight budget it can be a fit. The tradeoff is that you are the installer and the service department. Professional design and installation means sensors are placed correctly, the panel is configured right, and a local technician answers when something breaks.
Does Sting Alarm serve Phoenix too?
Yes. We serve the Las Vegas valley and the Phoenix metro with our own local teams, with offices in both cities.
