I recently left a new customer's house, and it's always rewarding to receive texts like this.

We believe in treating all our customers like family, providing them with the same level of care and respect. Unlike larger companies, we don't view our customers as just numbers. Instead, we focus on building strong relationships, listening to their needs, and treating them with honesty and respect.

This approach has been instrumental in our success, which dates back to 1970.

A customer's custom spaces were equipped with several strategically mounted TVs. The installation featured a 50” TV with a hidden cable box discreetly positioned between custom bookshelves, as well as a 75” TV positioned to harmonize with the forthcoming custom furniture.

Licensed & Insured Since 1970.
Don't trust your expensive devices to be mounted by someone who isn’t. The cost may be cheaper but when they damage your home or device you are paying a lot more and left holding the bag.

Our experience speaks for it self.

It’s wild how many people are jumping into the home security & automation space lately with zero real knowledge of how these systems actually work.

This isn’t plug-and-play WiFi gadgets from a big box store. This is life safety. This is fire systems, intrusion detection, structured wiring, networking, programming, integration, code compliance, and protecting families and businesses.

You can’t learn this overnight from YouTube and a distributor account.

Let’s also be clear about something — unlicensed work in this industry is illegal. Period.

And when someone hires an unlicensed installer, the risk doesn’t fall on the installer… it falls on the customer.

• Systems fail inspections
• Insurance claims get denied
• Fire systems don’t trigger properly
• Cameras miss critical events
• Networks are left vulnerable
• Liability becomes a nightmare

When something goes wrong, “I didn’t know” doesn’t protect you.

This industry takes proper licensing, certifications, training, field experience, and accountability. There’s a massive difference between selling equipment and engineering a reliable, code-compliant system that actually protects people.

We’ve been doing this since 1970 — over five decades of real-world experience through every generation of technology.

And the biggest proof?

Countless customer referrals.

When your work is done right, your reputation grows on its own.

If you’re getting into this business, respect the craft. Do it legally. Do it properly. Get trained. Get licensed. Learn the codes. Understand networking. Understand life safety.

Because when you’re dealing with someone’s home, family, or business — “figuring it out as you go” isn’t good enough.

Experience matters. Licensing matters. Doing it right matters.

This particular project presented several challenges. However, our extensive experience enabled us to overcome the obstacles within the walls and complete the task successfully. The speakeasy room is now complete, featuring a 55” Samsung frame TV, LED light-up shelves, all on a finished wood decorative wall. All wiring has been concealed, eliminating the need for any patching.
