Cable tunnels, as the name suggests, are tunnel-like structures used for laying cables. They are usually built of reinforced concrete, brick or steel pipe, etc., with a long and narrow space, and their height and width are designed according to actual needs, generally about 1.8 meters high and 1.5 meters wide. These tunnels not only provide a safe place for a large number of cables, but also greatly facilitate the routine inspection and maintenance of cables.

Cable tunnels play a crucial role in power transmission. They not only protect the cables from the erosion and damage of the external environment, but also ensure the stability and safety of power transmission through reasonable layout and structural design. Especially in the vicinity of power plants, substations and other power hubs, as well as river tunnels, airport runways and other areas difficult to excavate, cable tunnels have become the inevitable choice for power transmission.

The Need for Video Surveillance

However, with the growing demand for electricity in cities and the increasing number of cable tunnels, the problem of their safety management is becoming more and more prominent. Cable tunnel environment is complex, the number of cables, once the fire, theft or accidental entry and other events, the consequences will be unimaginable. Therefore, the cable tunnel video surveillance has become a necessary means to ensure its safe operation. Shenzhen DX-DLS100-SP Cable Tunnel Video Surveillance System is able to realize comprehensive monitoring and management of multiple key aspects of cable tunnels. comprehensive monitoring and management of multiple key aspects, including but not limited to the following:

1, infrared irradiation: very useful for night or tunnel interior with low light.

2, auto-focus: the camera has an auto-focus function, according to the changes in the scene automatically adjust the focus to ensure that the image is always clear.

3, motion detection: the system can detect moving objects in the tunnel, once abnormal movement is detected, the system can automatically trigger an alarm and record the relevant video.

4, long service life: the system design takes into account the durability and reliability, the use of high-quality materials and components to ensure that in harsh environments can also be long-term stable operation.

5、Real-time all-round image monitoring: the system is able to carry out 24/7 real-time monitoring of the tunnel's internal environment, tunnel entrances and exits, cable joints and other key locations to ensure that there are no blind spots.

6, digital video surveillance functions: the system has the standard functions of modern digital video surveillance system, including video capture, storage, alarm and linkage control.

7, digital storage video: all images captured by the camera will be given a number with a date and time label, and then stored in digital format. This allows for easy retrieval and playback.

8, image retention time: the system design requires image retention time of not less than 30 days to meet the needs of safety supervision and accident investigation.

9, abnormal information automatically pop-up: when the system detects anomalies, it will automatically pop-up the relevant screen, so that the operator can immediately notice and take action.

10, manual operation to switch the screen: the operator can also manually switch the screen through the keyboard or other control devices to view any section of the real-time monitoring images.

The introduction of the video surveillance system enables real-time all-round monitoring of the tunnel's internal environment, entrances and exits, cable joints and other key locations. Once abnormal conditions are detected, such as fire and smoke, personnel intrusion, etc., the system will immediately trigger the alarm mechanism and automatically push the relevant images to the monitoring center to provide timely and accurate early warning information support for management personnel.
