Legacy System Upgrades NYC - Taking Over Failed Installations
Legacy System Upgrades in NYC
Connextivity specializes in upgrading legacy security systems and taking over failed installations throughout NYC. We handle analog to IP camera upgrades, outdated access control replacement, legacy intercom modernization, and repairing systems other installers couldn't fix. Diagnostic assessments start at $225/hour with upgrade projects starting at $2,000 depending on scope. We frequently preserve existing infrastructure to reduce costs.
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.
