Network cameras are still significantly more expensive than their analog counterparts. When it comes to supporting key Quality of Service (QoS) functions, advanced and costly network equipment is often necessary to overcome the inherent limitations of Ethernet. Additionally, IT engineers must configure a full IP network, including LAN switches, routers, and firewalls, which makes the setup more complex and expensive compared to traditional CCTV systems. This complexity creates a major barrier for transitioning from analog to digital solutions.
Moreover, standard Ethernet bandwidths—such as 100 Mbps or 1 Gbps—are insufficient to handle the data demands of high-quality video streams. As a result, IP-based systems rely on compression techniques that can degrade video quality and introduce latency, especially when high refresh rates are required. This delay is unacceptable for real-time video analytics applications that demand high resolution, zero latency, and advanced performance.
Until recently, the only viable option for transmitting uncompressed high-definition video in surveillance was HD-SDI technology. It supports up to 1080p at 30fps over existing coaxial cables like RG59U, or even higher-grade RG6 or RG11 cables. HD-SDI has been the go-to solution for upgrading analog systems to digital while reusing existing infrastructure.
However, a new alternative has emerged: CCTV systems based on Ethernet Cat cables. One of the most promising technologies in this space is HDBaseT.
HDBaseT is a groundbreaking standard that allows the transmission of uncompressed high-definition video, audio, network data, control signals, and power through a single Cat cable using a standard RJ45 connector. This feature, known as "5Play," simplifies installation and reduces costs dramatically.
Developed by Valens, an Israeli semiconductor company, HDBaseT was introduced in 2010 with the formation of the HDBaseT Alliance, which included industry leaders like LG, Samsung, and Sony. The standard quickly gained traction among professional AV installers and is now being adopted by CCTV integrators who seek long-distance transmission, ease of installation, reliability, and excellent video quality—all at a lower cost.
Valens’ Cat cable CCTV solution leverages HDBaseT technology to deliver full HD video, audio, power, and control signals over a single CAT5e or CAT6 cable, up to 150 meters. This makes it ideal for applications requiring real-time, high-resolution video such as video analytics, forensic investigations, and security monitoring.
One of the biggest advantages of this system is its ability to maintain signal integrity without any loss in quality. It delivers 1080p@60Hz video with zero latency (<10 microseconds), ensuring smooth operation for PTZ cameras and alarm systems.
In terms of cost and simplicity, Cat cable CCTV is easy to install and offers plug-and-play functionality. Some industry experts claim it can transmit signals up to 50% farther than similar products. This makes it a powerful alternative to traditional analog setups, especially for those looking to avoid complex IP infrastructures and the need for IT professionals.
The system also reduces the number of cables needed, allowing multiple signals to be transmitted via a single cable. This not only lowers costs but also streamlines installation processes.
Looking ahead, the HDcctv standard—originally designed for digital serial transmission of HDTV over coaxial cables—has introduced a 2.0 version that supports Cat5 cables as well. Valens’ Cat cable CCTV solution was selected as the core technology for the new HDcctv CX specification, enabling HDcctv functions to run over Ethernet cables instead of coaxial ones.
This shift is helping to accelerate the adoption of HDBaseT technology and is pushing high-definition digital devices toward becoming the new market standard. Manufacturers, installers, and integrators are increasingly seeking solutions that deliver high-quality video while reducing costs and complexity.
It’s clear that the global infrastructure for high-quality digital CCTV is shifting toward Cat5 (LAN) cables due to their ease of use, affordability, and reliability. As a result, IP-based CCTV systems are gaining popularity, offering a modern, scalable, and efficient alternative to traditional analog setups.
