Core Responsibilities

Primary Functions

Conduct detailed site surveys and pre-installation assessments for audio and video intercom projects, documenting existing wiring, mounting locations, signal path, power availability, and any network or structural constraints that could impact installation and system performance.
Install surface- and flush-mount intercom stations, hands-free and handset units, door strike control hardware, master stations, and remote monitors, ensuring mechanical stability, correct orientation, and vandal-resistant mounting where required.
Perform structured cabling installations (CAT5e/CAT6/CAT6a) and terminate RJ45 connectors, punch down on 110 blocks, and install conduit or raceways per job specification while adhering to industry standards for bend radius and cable management.
Configure IP intercom and video intercom systems (SIP and proprietary protocols), program SIP accounts, allocate static IPs or DHCP reservations, and integrate units with network switches, VLANs, PoE, and firewalls in coordination with IT teams.
Commission and troubleshoot VoIP-enabled intercoms, verify audio/video quality, latency, echo, codec compatibility, and hand-off to SIP servers or hosted PBX; run SIP registration tests and adjust QoS settings when necessary.
Wire and connect power supplies, PoE injectors, and UPS/battery backup systems for intercoms and door strikes; calculate load requirements and ensure proper grounding and surge protection for low-voltage equipment.
Integrate intercom systems with access control panels, electric strikes, magnetic locks, and elevator control interfaces; program relay outputs, monitor inputs, and verify secure door release functionality during commissioning.
Mount and align outdoor camera modules and vandal-resistant housings, route coax or network cabling for video intercoms, and perform camera lens, field of view, and lighting checks to ensure clear identification at typical approach distances.
Perform comprehensive system testing and acceptance procedures, including loopback tests, call transfer, paging, intercom-to-phone bridges, event logging, and end-to-end verification between tenant units and building management consoles.
Create accurate as-built documentation, run diagrams, network topology maps, punch lists, labeling, and final commissioning reports that include firmware versions, serial numbers, IP addresses, and warranty registration information.
Provide user training for building staff, property managers, and residents on basic operation, user enrollment, temporary access codes, and system maintenance tasks; supply user guides, quick-start materials, and escalation contacts.
Execute preventative maintenance and field service repairs, replacing faulty boards, microphones, speakers, or cameras; diagnose intermittent faults with multimeters, cable testers, and protocol analyzers; and complete service tickets with detailed root-cause analysis.
Collaborate with project managers, electrical contractors, and general contractors to sequence installation activities, coordinate onsite deliveries, ensure compliance with construction schedules, and provide timely status updates for project tracking.
Adhere to building codes, local electrical regulations, NFPA low-voltage requirements, and OSHA safety standards while performing installations on ladders, lifts, rooftops, and in confined mechanical spaces.
Maintain inventory of intercom parts, cabling, connectors, power supplies, and tools; submit material take-offs, RMA requests, and recommendations for spare parts to reduce downtime and speed service response.
Troubleshoot network-related intercom failures, analyze switch logs, check PoE budgets, identify IP conflicts, work with VLAN/QoS settings, and liaise with the client’s IT or managed service provider to resolve connectivity issues.
Update and maintain firmware on intercom devices and associated controllers, follow manufacturer patching recommendations, and validate compatibility with integrated systems prior to deployment in production environments.
Read and interpret technical drawings, wiring schematics, riser diagrams, and manufacturer installation guides; escalate design discrepancies and request engineering clarifications when required for safe and compliant installations.
Perform quality control audits on installed systems, verify termination standards, ensure weatherproofing and sealant application for outdoor units, and sign off on completed installations only after passing defined acceptance criteria.
Respond to after-hours service calls and provide emergency support for critical entry or egress failures; prioritize safety and temporary secure solutions while scheduling permanent repairs.
Participate in continuous improvement by providing installation feedback to engineering and product teams, suggesting practical improvements to mounting hardware, firmware features, or cabling approaches to reduce field service time.
Ensure all customer-facing interactions are professional, record all service activity in work-order systems, capture photographic evidence of completed work, and obtain customer sign-off to close service tickets.

Secondary Functions

Assist in preparing project estimates by providing field-based labor-hour and material quantity assessments.
Support the development of standard operating procedures (SOPs) and installation checklists to increase consistency across the field team.
Participate in pre-construction meetings and provide input on access, staging, and cabling pathways.
Mentor junior technicians and apprentices on best practices for low-voltage installation and customer engagement.
Participate in periodic safety meetings, tool-box talks, and contribute to the site-specific safety plan.
Coordinate with third-party vendors (fiber crews, electricians, elevators) to schedule cutovers and minimize tenant disruption.
Test interoperability with third-party systems such as building management systems (BMS), concierge station integrations, and mobile app provisioning.
Assist sales teams with technical clarifications and field surveys when scoping new proposals.
Maintain certification and complete manufacturer training or refresher courses as assigned.
Provide detailed handover packets for turnover to operations and maintenance teams.
