Longgang Tian'an Digital City is located in the central city of Longgang, Shenzhen, adjacent to the main hall of the Universiade. The park covers an area of 120,000 square meters and has a construction area of 500,000 square meters. It was built in 2006 and completed in 2014. The park can accommodate 800 growth enterprises such as innovative technology, design creativity and financial services, and can introduce about 20,000 high-quality talents. The annual output value of high-tech products can reach 20. In addition, it will not only realize the industrial gathering and upgrading of Longgang Central City, but also radiate and promote the development of high-tech industries in the surrounding areas of Longwanhui with Longgang as the intercity center.

The video surveillance system in the campus all uses network cameras. The camera power supply is powered by 12V DC, and a total of 56 network cameras are available outdoors. The relevant leaders of Tianan Digital City considered that Shenzhen belongs to the strong minefield, and the annual thunderstorm day exceeded 80 days, which made higher requirements for video surveillance lightning protection. In order to meet the needs of all-day operation of outdoor cameras in the Tian'an Digital City Park, Kiloamp Technology recommends abandoning the traditional two-in-one lightning protection system. It is recommended to separately protect the camera power supply from the network line, and install the Kiloamp power supply and network signal lightning protection device respectively. After more than 2 years of operation, the system is running stably, no signal is lost, and lightning damage occurs.
