Red Pointer Pedestrian OKnlooker Artifact Laser Pointer
A network video shows that this laser pointer is installed next to the sidewalk. Consists of several yellow "iron stakes". Pedestrians were sprayed with water as soon as they crossed the line at a red light. Many pedestrians were curious after being sprayed across the line, and they took pictures of the "artifact". "It took more than two months from the research and development to the use of the system." Daye City Public Security Bureau Vanke Chief told the Beijing News reporter. The "artifact" is composed of two parts: "Pedestrians crossing red light automatic recognition and snapping system" and "Pedestrian crossing road laser pointer rainbow barrier system". A total of more than 1.3 million yuan has been invested in advanced R & D and manufacturing including the database.

Vanke said. Local pedestrians who have run through red lights have been difficult to manage. In addition, Daye has to select national civilized cities. The police then worked with a local company to develop the system and device. According to reports, the traffic police department of Daye has also inspected the road brakes in Wuhan and the surveillance cameras in Shenzhen in the early days to prevent red light "artifacts". In the end, it was decided to draw on the "Automatic Recognition and Capture System for Pedestrians Breaking into the Red Light". And added water spray, laser pointers and sound reminders.
You can actually use any laser pointer crow, but the difference is that the 532nm green laser is the brightest color for the human eye, and the green laser is 5-10 times brighter than any other laser color... Therefore, 100mW green is better than 100mW blue Color, red or violet lasers are much brighter. In addition, this type of bird repellent is performed during the day, so you need as bright colors as possible. Otherwise, the herd will not be significantly affected.
