Haydon HAY-HDPVB02 Single‑Channel HD Power & Video Pigtail Balun (BNC→RJ45, 4K/8MP capable)

Introduction to the Haydon HAY-HDPVB02 and its key features

Haydon HAY-HDPVB02 — single-channel passive power & video pigtail balunis a compact accessory designed to simplify CCTV cabling by carrying analogue and HD video plus DC power over UTP (CAT5e/CAT6) instead of coax. Aimed at installers, integrators and anyone retrofitting camera systems where Ethernet cable already exists, this pigtail-style balun offers a low-cost, low-complexity way to extend camera runs, reduce cable clutter and make use of existing infrastructure. The unit supports a broad range of formats (CVBS, AHD, HD-CVI, HD-TVI) up to 4K/8MP in many practical setups, and includes built-in transient/surge (TVS) protection and ESD filtering for added device protection.

Detailed description of specifications and benefits

The HAY-HDPVB02 is a passive single-channel pigtail balun that pairs a short in-camera BNC + DC barrel pigtail with an RJ45 UTP interface (or push-pin terminal style variants) at the far end. This form factor is ideal for mounting directly inside camera housings or junction boxes so that installers can terminate existing UTP runs to an RJ45 or push-pin block at the DVR/NVR end.

• Model / Type:HAY-HDPVB02 — passive single-channel power + video pigtail balun.
• Video formats supported:CVBS, AHD, HD-TVI, HD-CVI (NTSC/PAL/SECAM).
• Resolution capability:Up to 4K/8MP depending on camera format and cable quality.
• Video distances (typical, format dependent):720p AHD ~350 m; HDCVI ~400 m; HDTVI ~250 m. 1080p ranges typically AHD ~200 m; HDCVI/HDTVI ~250 m. 4MP/4K/8MP ranges typically ~150–200 m. Vendor tables apply.
• Power transmission:Power over UTP up to ~100 m depending on supply voltage, cable gauge and camera current draw. Compatible with 12 VDC in most cases; some listings indicate compatibility with 24 VAC options.
• Connectors:BNC male (approx. 150 mm coax lead) and 2.1 x 5.5 mm DC barrel on the pigtail; RJ45 port for UTP connection and/or toolless push-pin terminal block variant for quick termination.
• Protection:Built-in TVS transient/surge protection and ESD/anti-static filtering; LED status indicator for basic diagnostics.
• Physical:ABS engineering plastic housing, pigtail mounting intended for in-camera installation; intended for indoor use unless an IP-rated variant is specified.

• Cable cost savings:Use existing CAT5e/CAT6 runs rather than running new coax and separate power, reducing labour and material costs.
• Flexibility:Works with multiple analogue and HD CCTV formats, so a single part covers many camera types during upgrades or mixed-format installations.
• Compact, installer-friendly form:Pigtail design fits inside camera housings, keeping connections tidy and local to the device.
• Protection:Integrated TVS and ESD filtering increase resilience against transient events and static, helping protect sensitive camera electronics.
• Diagnostic aid:LED status indicator simplifies fault-finding and confirms basic connectivity at a glance.

Use cases and scenarios where the HAY-HDPVB02 excels

This balun is particularly useful in several common scenarios encountered by installers and facility managers:

• Many commercial and residential buildings already have CAT5e/CAT6 runs for network upgrades. When CCTV needs to be added or cameras replaced, the HAY-HDPVB02 lets you leverage that cable for video and power without expensive new coax runs.

• When cabling space or pathways are limited (trunking, conduits, or underfloor ducts), using UTP for multiple services reduces the number of separate cables required and simplifies management.

• For single-camera runs up to the vendor-stated distances, this balun supports HD and 4K-capable cameras in many real-world installations. It’s a straightforward choice for retail, office, school and small industrial sites.

• The pigtail form factor makes it a fast swap-out item when a camera’s pigtail is damaged or when converting a camera input to UTP at short notice — useful for service vans and stock kits.

Comparisons with similar products in the market

Baluns and power/video transmitters fall into two broad categories: passive pigtail baluns like the HAY-HDPVB02, and active or powered baluns/extenders that include amplifiers or PoE conversion circuitry. Understanding the differences helps pick the right tool for the job.

• Advantages: Low cost (suggested retail around $11.99), compact, no power required in the balun, simple installation, suitable for relatively short to medium runs where cable quality and camera output are adequate.
• Limitations: Range is dictated by signal attenuation and power voltage drop; fewer features than active extenders and typically intended for indoor use unless an IP-rated housing is provided.

• Advantages: Can amplify signals for longer runs, convert to/from PoE for easier power sourcing, and sometimes include surge suppression and isolation features. Better suited to long-distance links or noisy environments.
• Limitations: Higher cost, require power or PoE, bulkier, and add complexity to the installation.

Compared with generic passive baluns, the HAY-HDPVB02 stands out for its combination of pigtail form factor, built-in transient (TVS) protection and LED diagnostics at a budget-friendly price point. For projects where runs fall well within vendor distance tables and the priority is minimal cost and simple installation, it’s often the preferred option. For longer runs or where PoE integration is desired, active extenders or PoE baluns should be considered.

Customer testimonials and user impressions

While specific user reviews vary by reseller, common themes from installer feedback and product pages include praise for the unit’s compact form, reliability and value. Representative, anonymized comments often reflect practical installation experiences:

• "Saved us time on a retrofit job — used the existing CAT5 runs instead of pulling coax through the ceiling. Worked with our AHD cameras up to 1080p without issues." — Installer, regional security firm.
• "Small, neat and easy to hide inside the camera housing. The LED helped us confirm power presence quickly during testing." — Facilities technician.
• "Good budget option for short-medium runs. We avoid them for runs close to the vendor distance limits, but for most store cameras they’re ideal." — Integrator.

These impressions align with the HAY-HDPVB02’s design goals: an economical, installer-friendly accessory that performs well for many common CCTV deployments. If you need formal lab-test performance or site-specific advice, consult the manufacturer’s datasheet and distance tables for exact conditions.

Conclusion: Why the Haydon HAY-HDPVB02 is a great choice

The Haydon HAY-HDPVB02 single-channel HD power & video pigtail balun is a practical, cost-effective component for CCTV installations where existing UTP cabling can be leveraged. It supports a wide range of analogue and HD formats up to 4K in typical conditions, offers useful protections such as TVS surge suppression and ESD filtering, and arrives in a compact pigtail form that simplifies in-camera mounting.

When your project priorities are low material cost, quick installation and compatibility with common HD CCTV formats, the HAY-HDPVB02 provides an excellent balance of performance and value. For longer runs or installations that require PoE integration or outdoor-rated protection, consider active extenders or IP-rated variants — but for everyday indoor retrofit and replacement tasks, this balun is a sensible, reliable choice.
