Integrating Design and Technology for 35 years




Northern California’s Premier Ketra Lighting Integration Firm

Technology should complement your architectural masterpiece, never compete with it. At AUDIOVISIONS, we partner with elite architects to integrate smart home automation into every project, so your designs stay uncompromised, your clients stay impressed, and your reputation remains unmatched.

Ordinary Lighting Diminishes Extraordinary Architecture

Too often, stunning homes across Northern California fall short of their full potential because lighting wasn’t considered part of the design language. Basic fixtures and fixed-output LEDs cannot support the design or purpose of each room. For discerning homeowners and architects, that disconnection becomes a visual and functional liability. Illumination should elevate the home, not diminish it.

Partnering with a certified Ketra installer ensures your home features the lighting it deserves. Ketra offers a dynamic, full-spectrum lighting experience with tunable white lighting that changes with the daylight. These human-centric lighting systems provide morning warmth, midday clarity, and evening calm. Unlike conventional LEDs, Ketra lighting is adaptable, supports circadian wellness, and renders art, materials, and finishes with exceptional accuracy. It’s not just smart, it’s human-centric.

Architectural details deserve lighting that responds with intelligence and intention. Spaces designed for stillness or celebration require unique layers of light that evolve with activity and atmosphere. In coastal homes, hillside estates, or city-view penthouses, Ketra captures what standard lighting misses: mood, texture, and time. With the right system, light becomes an architectural material, not an afterthought.

AUDIOVISIONS: Northern California’s Ketra Integration Specialist

AUDIOVISIONS brings decades of smart lighting control and design expertise to the most exclusive homes in Northern California. As a certified Ketra dealer, we don’t just install lighting; we engineer light as a living element in your space. Our integration process is tailored for custom estates, smart home environments, and design-forward residences that require discretion and precision.

We collaborate directly with architects, interior designers, and builders to ensure Ketra’s full capabilities are aligned with each home’s unique character. From Palo Alto to St. Helena, our team designs and programs scene-based lighting systems that elevate daily routines, showcase interiors, and promote well-being.

Whether we’re working on a new build in Atherton or retrofitting a Napa Valley estate, our approach remains the same: honor the vision, protect the design, and deliver an exceptional lighting experience. Every detail, from fixture selection to final calibration, is managed with care. As a Ketra installer, AUDIOVISIONS does more than just install lighting in Northern California homes. We make lighting an integral part of your home and everyday living.

Ketra Lighting That Enhances Wellness, Beauty, and Design

Ketra transforms how light is felt, seen, and experienced in the home. Its tunable white spectrum mimics natural sunlight, shifting color temperature and intensity throughout the day. Wake gently, maintain focus throughout the day, dine under perfect warmth, and relax into the evening with purposeful lighting design. With Ketra, your home becomes a wellness-enhancing environment.

Ideal for estates with abundant glass, extensive art collections, or bold interior finishes, Ketra's advanced color rendering and TruBeam optics ensure every element is shown in its best light. For homes perched in the hills or nestled in wine country, Ketra enhances natural light while preserving scenic views.

Integrated with Lutron HomeWorks or Crestron, Ketra scenes are controlled with the same ease as climate, AV, and shading systems. We program spaces to align with how you live, blending automation with aesthetic nuance. Whether you're building your dream residence or refining an existing masterpiece, AUDIOVISIONS delivers Ketra lighting as it was meant to be: seamless, personal, and transformative.
