OUR CLIENTS

Taking Over Failed Installations & Upgrading Legacy Systems

Your security system isn't working. The original installer went out of business, stopped returning calls, or can't fix ongoing issues. Your analog cameras provide footage too grainy for identification. Your proximity card access control can be cloned with a $30 device.

We specialize in taking over failed installations and upgrading legacy systems, diagnosing problems other installers missed, preserving existing infrastructure where appropriate, and delivering systems that actually work.

Why Connextivity

Diagnostic Expertise

We specialize in diagnosing complex problems other installers can't fix. Our combination of security expertise, IT networking knowledge, and manufacturer certifications identifies root causes, not just symptoms.

Cost-Effective Upgrades

We preserve existing infrastructure where appropriate—camera mounts, conduit, cabling, and door hardware—reducing upgrade costs significantly while delivering modern capabilities.

We Fix What others Couldn’t

Many clients come to us after other installers failed to resolve ongoing issues. We've rescued installations from national companies, local installers who disappeared, and systems that never worked correctly.

Phased Upgrade Options

We understand budget constraints. Phased approaches allow critical components to be replaced first with additional upgrades implemented as budgets allow, spreading costs over 3-12 months.

Multi-System Integration

Legacy systems often operate cameras, access control, and intercoms independently. We integrate these systems even when upgrading components from different manufacturers and eras.

LEGACY SYSTEMS WE UPGRADE

Analog to IP Cameras

Grainy footage replaced with HD or 4K IP cameras providing clear identification footage. Modern video management software with remote viewing, extended retention, and camera integration. Existing cabling often reused with adapters to reduce costs.

Outdated Access Control

Vulnerable proximity card systems replaced with encrypted MIFARE DESFire EV3 credentials. Modern platforms with cloud management, mobile credentials, and camera integration. Existing door hardware and wiring often preserved.

Legacy Intercom Systems

Audio-only intercoms replaced with HD video IP intercoms from 2N and Axis. Mobile app unlock, resident directories, visitor management, and access control integration. Existing wiring reused where possible.

Failed Alarm Systems

Wireless-only systems with jamming vulnerabilities replaced with hardwired sensors and commercial-grade encrypted wireless from DSC, Honeywell, or Bosch. Professional monitoring and camera integration available.
