i-PRO MC-75-B100M-3 75W Surveillance Power Supply

The i-PRO MC-75-B100M-3 is a centralized 75W power supply designed for mid-to-large surveillance installations requiring distributed power to network cameras, illuminators, intercoms, and access-control readers from a single source. The FPO75-B100M8NL4E4M platform delivers steady-state 75W output, eliminating the operational complexity and cost overhead of deploying multiple individual PoE injectors or smaller supplies across a facility. This architecture reduces cable runs, simplifies circuit isolation, and centralizes power monitoring and failover logic in a single equipment rack or cabinet.

Key Features

• 75W Rated Output: Steady-state capacity sufficient for 8-12 standard 1080p IP cameras or equivalent mixed load of cameras and auxiliary devices (heaters, illuminators, door readers). Eliminates per-device power bottlenecks on larger deployments.
• Centralized Distribution Architecture: Single source feeds a terminal block or distribution panel, reducing per-camera power-injection overhead and simplifying circuit isolation for maintenance and troubleshooting.
• i-PRO Ecosystem Integration: Native compatibility with i-PRO camera systems and video management platforms; output voltage and current spec'd for direct integration without additional regulators or converters.
• Climate-Controlled Enclosure Mounting: Designed for rack or cabinet installation in controlled environments. Ventilation clearance prevents thermal throttling during sustained 24/7 operation.
• Isolated Input Circuit Protection: Accepts dedicated breaker or surge-protection feed from building panel, isolating the supply from upstream electrical transients and reducing MTTR on power failures.
• Multi-Output Terminal Block Distribution: Enables functional circuit separation (primary camera lines, auxiliary loads, redundancy feeds) within a single supply footprint, lowering total cost of ownership versus distributed supplies.
• Modular Deployment Model: Pair multiple units for larger installations (150W, 225W+) without redesigning power architecture, supporting facility growth and phased expansion strategies.

Deployment Scenarios & ROI

Centralized power supplies like the MC-75-B100M-3 are cost-optimal for facilities with 10+ IP cameras concentrated in a single building or zone. Rather than injecting PoE at each camera location or deploying a PoE+ switch (which adds capex and management overhead), a single 75W source mounted in a central rack eliminates cable runs, reduces per-port licensing in some VMS platforms, and provides a single point of power-cycle control for system-wide resets. Integrators deploying access-control readers, door intercoms, or IR illuminators alongside cameras gain the ability to size and manage their power footprint predictably—avoiding the surprise of a standard PoE switch undersizing when mixed loads exceed per-port budgets.

In multi-tenant or campus environments, a centralized supply simplifies billing and power allocation by function. Building maintenance teams can isolate surveillance power from general building power, reducing diagnostic time when electrical issues occur and enabling targeted UPS battery backup for critical camera zones without protecting non-essential loads.

Integration & System Architecture

The MC-75-B100M-3 integrates directly into i-PRO surveillance networks via standard terminal-block output. Verify output voltage (typically 12V DC or 24V DC depending on SKU variant) against your camera and device specifications before deployment. All i-PRO IP cameras and compatible auxiliary devices (illuminators, heaters, access readers) operate on standard voltage outputs; no additional regulators or converters are required. For multi-site or redundant power configurations, loop multiple supplies through a distribution panel with individual circuit isolation per supply, enabling N+1 failover logic at the cabinet level.

The supply operates independently of network connectivity—power delivery is purely DC hardware, with no dependency on VMS communication or software configuration. This architectural simplicity ensures that even during network outages or VMS maintenance windows, camera power remains stable and uninterrupted. Pair with surge-protection panels and dedicated building-panel breakers to isolate the supply from upstream electrical transients and load sharing conflicts with HVAC or lighting circuits.

Sizing & Total Cost of Ownership

A single 75W supply powers approximately 8-12 standard 1080p IP cameras at typical PoE load per RFC 802.3af/at specifications (7-15W per camera depending on heater activation and IR intensity). For larger installations, deploy two or more supplies on separate circuits with isolated output terminals; this strategy is more cost-effective and operationally safer than attempting to daisy-chain supplies or over-subscribe a single unit. The modular approach reduces the risk of single-point power failures cascading to an entire facility and simplifies circuit isolation for maintenance. When budgeting a surveillance system, the MC-75-B100M-3 eliminates per-port PoE switch licensing and reduces Ethernet switch capex by concentrating power off-network, lowering total five-year cost of ownership versus distributed PoE architecture on larger deployments.

Perspective based on aggregated IPSD and affiliated engineering team experience.

In our experience, the i-PRO MC-75-B100M-3 is a no-nonsense power supply that works best in tightly scoped i-PRO camera deployments where you're powering 8-15 devices from a single rack location. We've seen it deployed successfully in retail chains, light-industrial facilities, and multi-unit apartment buildings where consolidating power into a central panel simplifies maintenance and billing. The key operational win is eliminating the need for per-camera PoE injectors or oversizing a network switch just to add power capacity. On a 12-camera retail roll-out, this supply typically saves integrators $800-1,200 in PoE switch licensing and simplifies future camera additions without network infrastructure redesign. That said, it's not a universal solution—if your cameras are geographically dispersed (multi-building campus, outdoor perimeter spread across 200+ meters), a distributed PoE approach using managed switches is simpler and more resilient. The MC-75-B100M-3 shines in density scenarios: server rooms, equipment closets, or single-floor retail.

Technical Highlights:

• 75W Steady-State Delivery: Rated for continuous 75W output without thermal derating, meaning you can run a full mixed load of 8-12 cameras plus heaters and illuminators 24/7 without power cycling or voltage sag. No surprise power resets during cold starts or peak load conditions.
• Terminal Block Output Distribution: Enables functional circuit isolation—separate terminals for primary camera feeds, auxiliary devices, and optional redundancy lines. Critical for troubleshooting and reducing MTTR when individual circuits fail.
• Centralized Single-Source Architecture: Eliminates per-device PoE injection; one supply, one circuit breaker, one surge protector. Simpler power budgeting, easier backup UPS sizing, and lower per-port licensing overhead in VMS platforms that charge per PoE port.
• i-PRO Native Voltage Compatibility: Output voltage and current spec'd directly for i-PRO cameras and accessories—no third-party regulators or converters needed. Reduces integration risk and warranty gaps.
• Modular Scaling Path: Deploy multiple supplies on isolated circuits for 150W, 225W+ capacity without redesigning power architecture. Each supply operates independently; failure of one unit does not cascade to others if outputs are properly isolated in the distribution panel.

Deployment Considerations:

• Verify output voltage (12V DC vs. 24V DC) against your specific i-PRO camera models and auxiliary devices before purchase. Voltage mismatch will immediately damage equipment—confirm via product datasheet or i-PRO technical support before deployment.
• Mount in a climate-controlled enclosure with at least 2 inches of clearance on all sides. 75W sustained draw generates measurable heat; inadequate ventilation will cause thermal shutdown or accelerate capacitor aging, shortening supply lifespan.
• Use appropriately gauged wire for output runs to distributed cameras. Runs longer than 50 feet from the supply to cameras require heavier gauge (typically 12 AWG or better) to avoid voltage drop; losses exceeding 2-3% will cause IR illuminator dimming and potential camera reboot loops under thermal stress.
• Isolate input power via a dedicated building-panel breaker rated for the supply's input current (typically 15-20A depending on utility voltage). Do not share the breaker with HVAC or lighting loads—electrical transients from large motor starts will corrupt the supply output and potentially reset cameras.
• For redundant power, deploy a second MC-75-B100M-3 on a separate utility circuit with isolated output terminals in the distribution panel. This avoids single-point power failure and enables you to cycle one supply for maintenance without shutting down cameras.

The MC-75-B100M-3 is an excellent fit for integrators building consolidated i-PRO camera systems in single-location or single-floor deployments. It eliminates the capex and ongoing complexity of distributed PoE infrastructure while maintaining operational simplicity and diagnostic clarity.
