We are a locally owned and operated security company that values honesty and integrity in all aspects of our business. Our major focus is on providing quality work and producing outstanding results. We are committed to creating a level of value unmatched by any of our competitors. We look forward to building lasting relationships with our clients and guarantee your satisfaction!

"It appears this company engages in misleading sales tactics to trap customers into automatic yearly contract renewals. As many other Google reviewers have pointed out, they never clearly explain that the contract renews automatically each year. If you want to cancel, you're required to do so in writing, 30 days before the renewal dateâ otherwise, you're locked into another year of service. While we were remodeling our home, I tried to cancel the service by phone. However, Christian offered to pause the contract for six months, which seemed helpful at the time. In hindsight, itâ s clear this was just a tactic to keep us tied to the contract. Despite numerous conversations with Christian, he never once mentioned the critical details about how to properly cancel or the automatic renewal process. After over two years of not using the service, I called to officially cancel, only to be informed that I still had six months remaining on the contract. This lack of transparency and the constant hurdles to canceling the service are extremely frustrating. I would caution anyone considering this company to be aware of these practices."

Alarm or security system installations FAQs

If you terminate your security system before your contract ends, you’ll likely have to pay a cancellation fee—often a percentage of the remaining contract balance. To avoid these fees, consider choosing a brand that offers contract-free plans, like SimpliSafe or Vivint. You can also negotiate with your provider to see if they provide pro-rated cancellation fees or special exceptions.

Paying for a security system is a valuable investment because it enhances your home’s safety and deters criminal activity. With millions of property crimes each year, having robust security measures helps protect your property and might even lower your insurance premiums. It's a worthwhile investment for lasting peace of mind.

The average cost to install security cameras ranges from $125 to $3,500, depending on the amount, type, and placement. To install a complete setup of four cameras, homeowners can expect to invest an average of $1,300 for labor and equipment. Installing multiple cameras gives you comprehensive coverage of vulnerable entry points and enhances overall property security.
