In the Death Note universe, surveillance technology plays a significant role in the investigation of Kira, the alias of the main character Light Yagami who possesses the Death Note. Surveillance cameras, wiretapping, and other forms of monitoring are used by law enforcement agencies such as the Task Force to track Kira's movements and activities in their efforts to apprehend him. This technology helps in gathering evidence, identifying suspects, and preventing further crimes orchestrated by Kira.
