Network cameras are still much higher in price than analog products. When supporting key QoS-related operations, higher-end expensive network equipment is required to cope with Ethernet's inherent limitations; in addition, IT engineers must set a complete IP. Network and configure LAN switches, routers, firewalls, and other related devices. This process is more complex and more expensive than analog systems familiar with the CCTV market, leading to a more difficult transition from analog to digital.
Finally, and importantly, because 100 Mbp and 1 Gbp of Ethernet data bandwidth cannot handle the amount of high-quality video native data required, IP-based solutions must use a compression mechanism that reduces video quality and increases High-speed refresh rate (RefreshRate) video delay. This is unacceptable for real-time video analytics applications that require high resolution, zero latency, and advanced.
Until now, the only option for uncompressed high-definition video in the surveillance area is HD-SDI technology, which delivers up to 1080P @ 30fps over existing RJ59U analog coax or even using more advanced RJ6 or RJ11 coaxial cables. Real-time high definition resolution video. HD-SDI technology is currently the natural choice for upgrading digital high-definition devices from analog solutions and using the same coaxial cable.
Today, there is a new option for delivering uncompressed high-definition video signals over network cables: CCTV systems based on Ethernet Cat cable solutions.
HDBaseT standard
The biggest advantage of HDBaseT is that only one Cat cable, which is commonly used in Ethernet networks, and a standard RJ45 connector can transmit uncompressed high-definition video, audio, network, control signals, and power at the same time. This is called "5Play." transmission.
This standard was first initiated by Valens, a supplier of semiconductor products from Israel. In January 2010, Valens and LG Electronics, Samsung Electronics, and Sony Pictures Entertainment jointly created the HDBaseT Alliance to jointly promote this new technology and make it more advanced. It is a new global standard for multimedia transmission. HDBaseT technology has long been widely used by professional audio and video installation vendors, and CCTV installation vendors and integrators are also eager to obtain the same advantages—long distance, easy installation, reliability, flexibility and low cost, while also having the best video quality. So HDBaseT has also started to offer solutions for the closed-circuit television market.
Cat Cable CCTV Monitoring Solution
Valens has introduced CAT cable CCTV solutions. Based on HDBaseT technology, Cat cable CCTV is a breakthrough in plug-and-play and digital connection technology for CCTV cameras. The Valens solution incorporates uncompressed full HD video, sound, up to 100W of power and various control signals, transmitted via a single 150m/492ft CAT5e/6 cable (as shown).
This convenience does not sacrifice signal quality. Cat Cable CCTV can deliver uncompressed high-definition video at an effective resolution of up to 1080P@60Hz, making it an ideal source for high-quality video storage and real-time monitoring. Used for video analytics, crime investigations, and forensic evidence. The technology also features zero delay (<10us), no image "glitches", etc. PTZ cameras and automatic alarm systems are particularly suitable for using these functions.
In terms of simplicity, quality, and cost, Cat cable CCTV is easy to install and plug-and-play. Some industry believe that the transmission distance is 50 percent longer than similar products. From the signal source to the receiving end, the total transmission distance can be long. Up to 150 meters.
With this CCTVoC technology, the integration of different signals has also become much simpler, allowing installers to reduce the number of required cables to just one cable and transmit multiple signals, realizing a "single cable" solution. Program. In terms of budget, it consists of the lowest-cost analog cameras, CAT5e/6 cables, and similar installation processes with traditional analog systems to form a low-cost system without the need to build a complex IP infrastructure or employ IT professional engineers. In addition, the architecture also reduces the cost of additional power cables and control signal lines, and does not require the installation of power infrastructure and power related professionals.
Expand the future
Recently, the HDcctv standard (for digital serial transmission of uncompressed HDTV signals via coaxial cable) followed by the broadcasting industry has introduced a new 2.0 standard, in addition to providing new features and supporting the transmission of HDccTV signals including optical fiber and Cat5. The Valens Cat Cable CCTV solution was selected as the core technology of its new CX specification.
The goal of the HDcctvCX specification is to allow all functions originally on the HDcctv interface to operate on Cat5e and Cat6 cables as an alternative to coaxial cable. This move is a boost for the promotion of HDBaseT technology. High-definition digital devices have become the market standard. At the same time, equipment manufacturers, installers, and system integrators all need solutions that can meet high-quality image requirements while reducing costs and complexity.
It is easy to notice that the physical infrastructure of high-quality digital CCTV around the world is increasingly relying on Cat5 (LAN) cables because it is very easy to use, cheaper than other solutions, and simpler to install. Robust and reliable. Due to this architecture, IP-based CCTV solutions have become increasingly popular.
