Speco H4FB2M 4MP HD-TVI Intensifier Bullet

Speco Technologies H4FB2M 4MP HD-TVI Bullet Camera with IR

Overview

The Speco Technologies H4FB2M is a 4MP HD-TVI flexible intensifier bullet camera designed for security integrators requiring a motorized zoom solution with integrated infrared capability. The H4FB2M features a 2.7-12mm motorized varifocal lens and grey housing, delivering 4MP resolution with day/night operation. This camera combines HD-TVI transmission with flexible intensifier technology for low-light performance, making it suitable for diverse deployment environments where zoom flexibility and IR illumination are required.

When this is the correct choice

The H4FB2M is the optimal selection for integrators specifying motorized zoom surveillance in compact bullet form. Choose this model when you need varifocal lens control (2.7-12mm range) to adjust field of view post-installation, integrated IR for night operation, and HD-TVI compatibility with existing or planned HD-TVI infrastructure. This camera works well in mixed outdoor/indoor environments where flexible framing and infrared supplementation provide operational flexibility without requiring separate lighting systems.

When to choose a different model

If your project requires fixed focal length to reduce system complexity, consider a fixed-lens HD-TVI model. For 4K resolution or higher frame rates, evaluate 4K HD-TVI options. If you need analog HD without motorized zoom, select a simpler fixed bullet. For IP-native environments where HD-TVI transmission is not preferred, compare IP-based 4MP motorized bullets instead. If vandal resistance (IK10) is mandatory, verify the H4FB2M's IK rating against project specifications before committing.

Optics and field of view

The H4FB2M is equipped with a 2.7-12mm motorized varifocal lens, delivering variable field of view and zoom control. The motorized design enables remote lens adjustment, allowing integrators to optimize framing without site visits. The varifocal range (2.7mm to 12mm focal length) provides both wide-angle and telephoto coverage, making the camera adaptable to changing scene requirements or future layout modifications.

Imaging performance and low light

This 4MP camera delivers 2560×1920 resolution in daylight and uses flexible intensifier technology for low-light operation. The integrated IR illumination supports night vision without external lighting. IR range and minimum illumination thresholds are optimized for the intensifier design, enabling usable video capture in near-dark environments where ambient light is minimal. The combination of flexible intensifier processing and IR LED arrays provides practical night operation across typical surveillance ranges.

Analytics and edge capabilities

The H4FB2M operates on the HD-TVI platform, which transmits video over coaxial cable (BNC). Onboard analytics are dependent on backend DVR/hybrid recorder capabilities rather than edge processing. Frame rate and video quality are managed through the recording device, allowing flexibility in feature selection based on the complete system configuration.

Video encoding and streaming

As an HD-TVI camera, the H4FB2M outputs uncompressed or minimally compressed video over coaxial transmission, avoiding the encoding bottlenecks of networked systems. This architecture reduces latency and simplifies integration with existing HD-TVI infrastructure. Video quality and frame rate depend on the recorder and transmission line quality.

Network and security

The H4FB2M uses HD-TVI coaxial transmission, which does not employ network-based authentication or encryption. Security is managed through physical cable integrity and recorder access controls. This analog/HD-TVI approach eliminates network cybersecurity vectors but requires secure physical installation and recorder authentication.

Environmental and durability ratings

The H4FB2M is housed in grey casing suitable for indoor and outdoor installations. Physical robustness and weather resistance are inherent to the bullet design. Exact IP and IK ratings should be confirmed against the datasheet. The motorized lens mechanism is sealed to resist dust and moisture ingress common in outdoor deployments.

Power and installation notes

The H4FB2M requires 12V DC power for operation. A junction box is included with the camera, simplifying wiring and power distribution at the installation site. The motorized lens draws additional current during zoom and focus adjustment; power specifications should be confirmed with the recorder or power supply used. Coaxial cable runs should follow standard HD-TVI installation practices, with attention to cable length and quality to maintain signal integrity over distance.

James Everett

The Speco H4FB2M represents a practical choice for integrators committed to HD-TVI infrastructure who require motorized zoom and IR capability. During deployment planning, the motorized 2.7-12mm lens provides the operational flexibility that fixed optics cannot match, reducing post-installation field service. The included junction box streamlines terminal wiring, saving labor on coaxial runs.

Technical Highlights:

• Motorized varifocal lens: 2.7-12mm zoom range allows remote framing adjustment without site visits, critical for projects with evolving surveillance zones.
• Flexible intensifier IR: Night operation via integrated IR eliminates external lighting dependency and reduces overall system footprint.
• 4MP resolution: 2560×1920 captures detail suitable for mid-range facial and license plate recognition over typical surveillance distances.

Deployment Considerations:

• Confirm motorized lens power draw matches your 12V power supply capacity, especially on extended coaxial runs where voltage drop may reduce available current to the lens motor.
• Plan junction box placement near the camera to minimize loose wire management and simplify future zoom/focus control integration with recorder firmware updates.

The H4FB2M is a solid fit for mixed outdoor/indoor HD-TVI systems where zoom flexibility and IR operation justify the motorized mechanism. Validate the complete system power budget and recorder compatibility before order confirmation.
