Ethernet channel: DisplayPort does not support Ethernet data and the standard does not have an audio return channel, while by using the latest version of HDMI, 100 Mbps HDMI Ethernet Channel (HEC) can be implemented. HEC is used primarily for audio control. The Ethernet channel can be used to provide an Internet connection between devices, especially when HDMI devices are used for streaming video or other content from the Internet. Advantages of HDMI in video surveillance HDMI cables have several advantages that make it superior over some interfaces like DVI and component video, especially in video surveillance systems. HDMI includes all components of both video and audio data in one cable, so there is no need for extra cables.

Because, everything is contained in one compact cable package. HDMI transmission line could be used instead of at most 13 similar transmission lines, thus the problem of cable clutter will be solved effectively. On the other hand, like many other modern data transmission cables, an HDMI cable is composed of a series of twisted pairs.

It has been proved that this cable manufacturing technology, is superior over other cables even huge coaxial cables for reducing noise and interferences. Also HDMI guarantees HDCP, thus video information is protected from copying during transmission, confirming its benefit in video surveillance. Why we should consider DisplayPort in addition to HDMI in video surveillance? In video streaming, choosing the types of video connection to stream the content to the display is an important issue. Over the years, delivering this content through HDMI, DVI, and VGA cables has been the most popular method.

In recent years, a technology called DisplayPort has been developed. It has slowly been adopted by motherboard and displays. By the est version DisplayPort 1.2, achieving to 4K60p resolution (3840×216060Hz) is possible, while HDMI only provides this resolution at half the frame rate or less. The most important advantage of DisplayPort 1.2 over the other standards is a Multi-Stream Transport (MST) technology, in which DisplayPort can transfer multiple video streams from one video output by using 21.6 Gbps bandwidth. Therefore, achieving up to 4 displays with 1080p resolution from a single DisplayPort output is possible, confirming the benefit of DisplayPort for video surveillance.

Conclusion The main digital connectors used on computers and display devices are DVI and HDMI. DisplayPort is a er connector mainly designed to replace VGA and DVI ports. The first choice to connect a device to display is HDMI which is commonly used in the most NVRs.

The cables are cheap and it also carries audio. On the other hand, HDMI has some limitations and is not a perfect choice for all purposes. In most cases HDMI is fine, but for really high resolutions and frame rates, other options might be taken into consideration. Since DisplayPort can support multiple displays and also due to its ability to connect to nearly any other type of monitor with an inexpensive adapter, getting a video recorder device which offers DisplayPort in addition to HDMI, is an admirable choice in video surveillance industry.
