Passive Twisted Pair Converter electro base PTR-102VP-HD+ 5MPix for AHD/TVI/CVI video transmission

Passive Twisted Pair Converter electro base PTR-102VP-HD+ 5MPix for AHD/TVI/CVI video transmission is a passive UTP/STP balun designed to carry analog HD video signals up to 5 megapixels over a single twisted pair cable. The device requires no external power and converts differential signals from AHD, TVI or CVI cameras to a format suitable for transmission over long runs of structured cabling. It is intended for CCTV installations where minimal cabling, simple deployment and compatibility with existing analog HD systems are required.

Advantages

The converter supports 5MPix resolution for AHD, TVI and CVI formats while remaining passive, which eliminates the need for power supplies at the camera or intermediary points. Its use of a single twisted pair reduces cable volume and installation time compared with coaxial runs. The passive design reduces points of failure and maintenance. The unit is compact and compatible with standard UTP/STP installation practices for CCTV, facilitating quick integration into existing systems.

Suitable for

• Transmission of AHD/TVI/CVI analog HD video signals over UTP or STP cabling
• Retrofit or expansion of CCTV systems to extend camera reach without active repeaters
• Installations where power to intermediate devices is undesirable or impractical
• Projects needing reduced cabling bulk and easier cable routing compared with RG-59 coax

Key specifications

• Supported video formats: AHD, TVI, CVI up to 5 megapixel equivalent resolution
• Transmission medium: single twisted pair over UTP or STP cable
• Operating mode: passive (no external power required)
• Connector types: BNC (video input/output) and terminal for twisted pair wiring
• Typical application: point-to-point video transmission over structured cabling

How to use

Connect the converter’s BNC video connector to the camera’s composite HD video output and terminate the other side to the recorder or receiver’s BNC input using a matching passive converter if required. Attach the twisted pair to the converter’s screw terminal or RJ-style terminal according to wiring color code and ensure correct polarity. Install one converter at the camera end and the matching passive unit at the recorder end to complete the transmission path. Test video presence and image quality after installation and adjust cable routing to minimize interference.

Usage recommendations

Use high-quality UTP/STP cable (Cat5e or higher recommended) and maintain proper pair integrity and minimal untwisting at termination points. For runs approaching the upper reliable distance for 5MPix signals, verify signal quality on-site and consider using active extenders if degradation occurs. Avoid running video twisted-pair cables parallel to high-voltage power lines to reduce interference.
