Network cameras are still significantly more expensive than their analog counterparts. When it comes to supporting key Quality of Service (QoS) operations, high-end and costly network equipment is often necessary to overcome Ethernet's inherent limitations. In addition, IT engineers must configure a complete IP network, including LAN switches, routers, and firewalls—making the setup more complex and expensive compared to traditional analog systems that are well-established in the CCTV market. This complexity makes the transition from analog to digital more challenging and less appealing for many users.
Furthermore, the data bandwidth of 100 Mbps and 1 Gbps Ethernet is insufficient to handle the high-quality video data required by modern surveillance systems. As a result, IP-based solutions rely on compression techniques that reduce video quality and introduce delays in high-refresh-rate video streams. This is unacceptable for real-time video analytics applications that demand high resolution, zero latency, and advanced processing capabilities.
Until recently, the only option for transmitting uncompressed high-definition video in the surveillance industry was HD-SDI technology. It can deliver up to 1080p at 30fps over existing analog coaxial cables, such as RJ59U, or even more advanced options like RJ6 or RJ11. HD-SDI has become the natural choice for upgrading from analog to digital systems while using the same coaxial infrastructure.
Today, a new alternative has emerged: delivering uncompressed high-definition video over standard network cables through Cat cable-based CCTV solutions.
**HDBaseT Standard**
The biggest advantage of HDBaseT is its ability to transmit uncompressed high-definition video, audio, network traffic, control signals, and power all through a single Cat cable with a standard RJ45 connector. This is known as "5Play" transmission.
Initially developed by Valens, an Israeli semiconductor supplier, the HDBaseT Alliance was formed in January 2010 by Valens, LG Electronics, Samsung Electronics, and Sony Pictures Entertainment. Together, they promoted this innovative technology and aimed to establish it as a global standard for multimedia transmission.
HDBaseT has been widely adopted by professional AV installers and is now gaining traction among CCTV professionals who seek long-distance transmission, easy installation, reliability, flexibility, and cost-effectiveness—all while maintaining the highest video quality. This has led to the development of HDBaseT-based CCTV solutions tailored for the security market.
**Cat Cable CCTV Monitoring Solution**
Valens introduced a Cat cable CCTV solution based on HDBaseT technology. This breakthrough allows plug-and-play digital connections for CCTV cameras, transmitting full HD video, audio, up to 100W of power, and various control signals via a single 150-meter CAT5e/6 cable.
This solution does not compromise on signal quality. Cat Cable CCTV delivers uncompressed high-definition video at an effective resolution of up to 1080p@60Hz, making it ideal for high-quality storage, real-time monitoring, video analytics, crime investigations, and forensic evidence. The technology also offers zero delay (<10μs) and no image glitches, making it particularly suitable for PTZ cameras and automatic alarm systems.
In terms of simplicity, quality, and cost, Cat cable CCTV is easy to install and supports plug-and-play functionality. Some industry experts claim that its transmission distance is 50% longer than similar products, allowing for a total reach of up to 150 meters from the source to the receiver.
With this Cat cable CCTV technology, integrating multiple signals becomes much simpler. Installers can reduce the number of cables needed to just one, transmitting multiple signals simultaneously and achieving a "single cable" solution. In terms of budget, this system uses low-cost analog cameras, CAT5e/6 cables, and a straightforward installation process similar to traditional analog setups. It eliminates the need for a complex IP infrastructure or specialized IT engineers, while also reducing the costs of additional power and control lines. No power infrastructure or electricians are required.
**Looking Ahead**
Recently, the HDcctv standard, designed for the digital serial transmission of uncompressed HDTV signals over coaxial cables, introduced a new 2.0 version. This update includes support for optical fiber and Cat5 cables. The Valens Cat Cable CCTV solution was selected as the core technology for the new HDcctvCX specification.
The goal of the HDcctvCX specification is to allow all functions originally available on the HDcctv interface to operate over Cat5e and Cat6 cables, offering an alternative to traditional coaxial cabling. This development is a major boost for the adoption of HDBaseT technology, helping high-definition digital devices become the new market standard.
At the same time, manufacturers, installers, and system integrators require solutions that meet high-quality image demands while reducing costs and complexity. As a result, the use of Cat5 (LAN) cables for high-quality digital CCTV is becoming increasingly widespread worldwide due to their ease of use, affordability, and reliability. Because of this architecture, IP-based CCTV solutions are growing in popularity.
