High performance, long lifespan, and Italian quality for reliable security systems.
In a video surveillance system, the coaxial cable is often considered a secondary component compared to the devices themselves. In reality, it plays a crucial role in ensuring image quality, transmission stability, and the long-term reliability of the entire installation.
For this reason, choosing the right coaxial cable is essential to guarantee consistent performance and minimize maintenance needs.
Transmission standards and the role of the cable
HDCVI, AHD, and HDTVI standards were developed to upgrade analog systems without completely replacing the existing cabling. However, high-definition cameras require a much higher bandwidth than traditional analog ones — from about 5 MHz up to over 150 MHz for 4K systems. This is why a high-quality coaxial cable becomes indispensable for stable transmission even over long distances.
The Cavel range for professional video surveillance
Cavel – Italiana Conduttori has developed the VSHD series, a complete range of coaxial cables specifically designed for analog, digital, and hybrid video surveillance systems. These cables ensure high performance and signal stability across all camera protocols and resolutions (HDCVI, AHD, HDTVI), and are also available in combined versions with integrated power conductors — simplifying installation and reducing setup time.
VSHD Cables with LSZH Sheath
- VSHD40 (micro-coaxial 3.6 mm): runs up to 250 m
- VSHD70: runs up to 400 m
- VSHD80: runs up to 500 m
- VSHD113: runs up to 700 m
The distances indicated refer to systems using HDCVI 4K cameras and may vary depending on installation conditions.
How to choose the correct cable diameter
The choice of the outer diameter depends on the available space in conduits and the specific installation environment. In general, it is recommended to select cables of at least 5 mm, preferably 6.6 mm, to ensure strength and resistance during installation.
Cables with smaller diameters (3.6 / 4 mm) are suitable only for extremely tight spaces and require careful handling, ideally by two installers. For instance, the VSHD40 model withstands a maximum tensile strength of 5.1 kg (50 N), while VSHD70 reaches 8.2 kg (80 N).
BNC connectors: quality and compatibility
Beyond the cable itself, the quality of the BNC connector has a major impact on the system’s overall performance. Cavel offers a range of compression-type BNC connectors specifically designed for video surveillance and broadcast applications. These connectors make termination easier and ensure a stable, long-lasting connection. Using 5.0 mm or 6.6 mm cables simplifies assembly and reduces installation time.
The advantages of Cavel quality
Cavel coaxial cables, produced by Italiana Conduttori, are 100% Made in Italy and come with a 15-year warranty. Every stage of production — from copper drawing to the final sheath — is carried out internally at the Gropello Cairoli (Pavia) plant, ensuring strict quality control and long-term reliability.
Video tutorials and technical training
To support installers and designers, Cavel provides a series of video tutorials on YouTube covering the correct termination of F, IEC, and BNC connectors. Each video explains the proper steps and offers practical advice to help avoid mistakes during installation.
Coaxial cables for TV systems: an update on diameters
For TV signal distribution systems as well, it is recommended to use 6 / 6.6 mm cables for both satellite and terrestrial signals. This ensures consistent performance over time and protection against 4G/5G interference, resulting in future-proof installations and satisfied customers.
