The background of the high-definition video surveillance industry on highways, with the increasing maturity of video technologies such as high-definition camera technology, video encoding technology, fiber optic transmission technology, and video exchange technology. The demand for high-definition, intelligent, integrated, and large-scale networking of video surveillance systems on highways is becoming increasingly urgent. However, how to effectively integrate the above advanced video technologies to form a comprehensive high-definition video networking monitoring system that integrates high-definition video capture, network transmission, exchange, large screen control, wall display, and storage has become the primary problem to be solved in the industry. Introduction to High Definition Video Surveillance Solutions for Highways, Olink Technology's Digital High Definition Surveillance Solution for Highways.

Toll station monitoring

Select high-definition/standard definition network cameras and upload video, audio, alarm, and various low-speed data signals to the toll station monitoring room through the UTN integrated business optical transmission network in a star, chain, or ring network manner; The monitoring room completes the storage and forwarding of videos, and can perform real-time image browsing and control through video workstations.

Tunnel monitoring

The optical fibers of the left and right tunnels form a ring network, which uploads the video images and related monitoring data of all fixed cameras and entrance ball machines to the tunnel management office through the UTN comprehensive business optical transmission network in a ring network manner. If there are special requirements, HD-SDI digital uncompressed high-definition system can also be used to directly transmit the video images and related monitoring data of the hole ball machine to the monitoring sub center; The tunnel management office mainly completes the storage and forwarding of videos, and can perform real-time image browsing and control through video workstations.

road surveillance

Using high-definition/standard definition network cameras, video images and related monitoring data are transmitted to the monitoring sub center through the UTN integrated service optical transmission network in a ring network manner; HD-SDI digital uncompressed high-definition system can also be used to transmit video images and related monitoring data to the monitoring sub center, thereby meeting users' strict requirements for real-time video and control.

Monitoring sub center

P Video Surveillance Solution: Install OLT for central business reception and switching equipment, Orlink Technology-NVR80 network storage system, and CM2600 video comprehensive management platform in the sub center; Digital HD video surveillance solution: Due to the addition of HD-SDI digital uncompressed HD system, HD-SDI optical transceiver and switching matrix need to be configured on the basis of IP video surveillance solution. All devices can be uniformly managed through the video comprehensive management platform CM2600; By using the standard Gigabit Ethernet interface of the OLT for receiving and switching equipment at the central office, it is easy to achieve networking between the monitoring sub center and the provincial center

The system realizes the access, transmission, exchange, storage, and management of video, audio, alarm, and various low-speed data signals; The transmission adopts a 1.25G fiber self-healing ring network method, combined with TDM time slot control technology, to completely solve network congestion, ensure real-time, reliability, and security of transmission; The entire network only needs to undergo one analog-to-digital/digital to analog conversion, which will not cause a decrease in video quality due to multi-level cascading of the system, meeting the needs of multi-level networked monitoring on highways;

The UTN integrated business optical transmission network can provide up to 40M exclusive bandwidth for each video channel, meeting the bandwidth requirements for 1080p, 1080i, and 720p high-definition digital video transmission; Save fiber optic resources, a single fiber can support up to 24 nodes and 96 high-definition/standard definition video access channels; Monitoring points with high real-time requirements can deploy digital uncompressed high-definition systems, including HD-SDI digital uncompressed high-definition cameras, optical transceivers, and switching matrices

Supports 1080p, 1080i, and 720p high-definition digital video encoding and decoding functions, and can provide multiple high-definition interfaces such as HD-SDI, HDMI, DVI, and YPbPr; Adopting distributed deployment and centralized management storage mode, supporting various storage architectures such as NVR, NAS, IP-SAN, FC-SAN, etc; Through the CM2600 video comprehensive management platform, unified configuration, maintenance, and management of all devices can be achieved. It also has functions such as user group and user level management, video storage, on-demand and publishing, and matrix switching
