Security · Automation · Southern California
Nelson Security designs access, alarms, cameras, network, and home automation as one stack for high-end residences and commercial properties in Southern California. Manufacturer-independent since 1985: we match the platform to the house, then keep it healthy after install.
Priority markets: Santa Barbara County · Westside LA · Conejo Corridor · Orange County Coast — all service areas →
Each page targets a specific decision path—so you can research the right system for your property, then we engineer the full stack around it and support it over time.
Biometrics, facial recognition, mobile credentials, visitor workflows, and door policies with video verification—from single entries to multi-site campuses.
Explore access control →Mission-grade panels, detectors, and monitoring pathways that integrate with access, video, and third-party systems—not a closed silo.
Explore alarms →High-resolution IP video with facial recognition, AI analytics, LPR, recording, and operator-friendly walls for estates, studios, and commercial sites.
Explore cameras →PoE switching, wireless, and structured cabling that carry cameras, doors, sensors, and AV without bottlenecks or dead zones.
Explore network →Lighting control, motorized shades, climate, AV, pool & spa, and integrated devices—manufacturer-independent design.
Explore automation →Service contracts and preventative maintenance for security, access, network, lighting, shades, and AV—so systems stay ready after install.
Explore service plans →Lease cameras, alarms, and jobsite fire protection through the build—plus remote viewing so owners can watch progress. Temporary coverage for the construction period.
Explore construction security →Property-based system design for owners, architects, and GCs. Spec it for subcontractors, or have us install—the design fee rolls into the project.
Explore design & consulting →Manufacturer-independent since 1985. We match the platform to the property—not a brand quota.
For properties with security teams, multi-door complexity, or high-stakes visibility, we deploy enterprise-class video and access platforms—AI analytics, unified management, visitor handling, and workflows that support faster verification when every second counts.
Typical fit: campuses, studios, multi-building commercial, guard or SOC-style operations.
When you want one management fabric for networking and physical security—cameras, door access, sensors, and switches under a single operational model—we design unified stacks that scale from a single building to multi-site estates without unnecessary license sprawl.
Typical fit: modern commercial sites, multi-structure residences, organizations standardizing on one ecosystem.
Intrusion should be the foundation that coordinates detection, arming, and response—not a closed island. We specify open, integration-friendly alarm platforms so panels, sensors, and access can work with the video and network you prefer.
Typical fit: mixed-vendor properties, upgrades that keep good hardware, life-safety + intrusion coordination.
Whole-home automation that unifies lighting, shades, entertainment, climate, and outdoor living with the same integration standard as security—scenes that feel architectural, not experimental. We specify the control system that fits the architecture, and integrate lighting, shade, and AV when they serve the property better.
High-end residential and commercial projects across four Southern California corridors—each with dedicated community pages.
How we choose platforms, why the stack is designed as one system, and what happens after install.
We match the platform to the property—not a brand quota. Enterprise video and access for staffed or high-visibility sites; unified cameras, access, alarms, and network when one operational model is the priority; open intrusion when mixed product stacks must coordinate. Lifestyle control is specified the same way: scenes that feel architectural, not experimental. Manufacturer-independent since 1985.
Each solutions page is a decision path, but we engineer the full stack around it. Door events should sit next to camera views; alarms should coordinate arming and video verification; lighting and shades should share the same integration standard as security—without app sprawl. Architecture-first design for residential estates and commercial properties.
Yes. High-end residential estates and commercial properties across Santa Barbara County, Westside Los Angeles, the Conejo corridor, and Orange County coast. Same architecture-first craft; different staffing and uptime priorities. We are based in Thousand Oaks and work those Southern California priority markets by appointment.
Ongoing service and preventative maintenance after install. Temporary construction-site security leased for the build, then removed. Property-based system design for owners, architects, and general contractors—whether or not we install, with the design fee rolling into the project if we do.
We are based in Thousand Oaks and work by appointment only for confidential residential and commercial projects in our Southern California priority markets. Call (866) 707-0927 or request a consultation. There is no walk-in showroom path.
