Technical specifications identify the ZdyCGTime Video Balun as a passive, transformer-coupled impedance matcher. It is designed to facilitate the conversion of 75-ohm coaxial signals to 100-ohm balanced signals over UTP (Cat5/6) cabling. Performance metrics demonstrate support for analog protocols including AHD, HD-CVI, and HD-TVI up to 8MP (4K) resolutions. As a passive induction device, it requires no external power source, utilizing a ferrite core to suppress common-mode noise during transmission.
Aggregated data indicates a tool-less press-fit terminal design, which provides a more reliable field connection than standard screw terminals. However, signal-to-noise ratio (SNR) calculations confirm that signal degradation is a mathematical certainty over distances exceeding 300 meters for 4K video. Material analysis confirms the plastic injection molding is designed for a compact footprint, allowing it to be housed within standard junction boxes. This hardware is strictly analog and cannot perform digital packet conversion.
- Signal compatibility: AHD, TVI, CVI, CVBS.
- Interface types: BNC (Male), UTP Terminal Block.
This balun functions as a bridge for legacy-to-digital infrastructure, a specialized role within the security camera accessories hardware group.
To protect these terminal points from oxidation and maintain signal fidelity over time, it is recommended to house the baluns inside a Bullet Security Camera Junction Box.
