G. Leff Security Systems
Smart Infrastructure

Enterprise-Grade
Network Infrastructure

Security is only as strong as the network behind it. We design and install enterprise-grade structured cabling, WiFi 6E, and IoT-ready infrastructure that keeps every camera, sensor, and access point connected and running.

Core Features

Every component engineered for reliability, speed, and future-proof scalability.

CAT6/Fiber

Structured cabling with CAT6A and fiber optic runs for maximum bandwidth and minimal latency across your entire facility.

WiFi 6E

Next-generation wireless coverage with WiFi 6E access points delivering multi-gigabit speeds and seamless roaming.

IoT Ready

Purpose-built network segmentation and protocols supporting thousands of IoT devices, sensors, and smart building endpoints.

Central Control

Unified management dashboard to monitor, configure, and troubleshoot every network device from a single pane of glass.

Why Professional Infrastructure Matters

A properly designed network is the backbone of every security system, smart building, and connected workplace.

Zero Downtime Reliability

Redundant pathways, failover switches, and UPS-backed infrastructure ensure your security systems never go offline, even during power events.

Future-Proof Design

Every installation is designed for tomorrow's demands. Our structured cabling supports 10Gbps+ today and is ready for whatever comes next.

Security-First Architecture

VLANs, network segmentation, and enterprise-grade firewalls isolate your security traffic from general use, preventing unauthorized access.

Performance Optimized

Professional site surveys and heat mapping ensure optimal access point placement, eliminating dead zones and guaranteeing consistent throughput.

Scalable from Day One

Whether you're starting with 10 devices or 10,000, our modular infrastructure scales seamlessly without ripping and replacing existing runs.

Single-Vendor Simplicity

One team designs, installs, and maintains your entire low-voltage infrastructure. One point of contact. One warranty. Zero finger-pointing.

Frequently Asked Questions

What is low voltage cabling and why do buildings need it?
Low voltage cabling is the wiring infrastructure that carries data, voice, video, and security signals throughout a building. It includes structured network cabling (Cat6/Cat6A), coaxial cable for CCTV, and fiber optics. Every modern building needs it for internet, phone systems, security cameras, and access control. G. Leff Security has been installing low voltage infrastructure since 1985.
What is WiFi 6E and should my building upgrade?
WiFi 6E is the latest wireless standard that operates on the 6 GHz band, offering faster speeds, lower latency, and less interference than older WiFi versions. Buildings with many connected devices — smart locks, security cameras, IoT sensors — benefit significantly from WiFi 6E. G. Leff Security designs and installs enterprise-grade WiFi 6E networks for commercial and multi-housing properties.
Can G. Leff Security handle structured cabling for new construction?
Yes, G. Leff Security provides complete structured cabling for new construction and retrofit projects. This includes network cabling, fiber optics, CCTV infrastructure, access control wiring, and smart building integration. We work with developers and general contractors across the East Coast, from Boston to Virginia.
