On May 23, 2019, at the invitation of the Taizhou Power Supply Company of Zhejiang Electric Power Company, we went to the Central Avenue in Jiaojiang District, Taizhou City, Zhejiang Province for a live demonstration. Because the local venue was relatively empty, we conducted a construction site in the distance. The simulation survey and clear and precise display of the locked target show the day and night of the HLN-TW100 night vision fog-photographing instrument and the locking of the ultra-long distance. The effectiveness of the live demonstration was confirmed by local leaders and met the needs of local power companies.
