Surveillance cameras used by Luke and Selina naturally wouldn't be ordinary.
Firstly, they had all sorts of functions
In A.I. mode, they could detect and lock onto unusual situations. The telephoto lens would automatically focus to get a clearer image, while the wireless communication function was a standard feature.
Secondly, they were very covert.
It was naturally against the law for Luke to install these things in Tokyo; it was too easy to use them to spy on private affairs, so they were very sensitive.
In his previous life, it was basically the police which installed long-focus cameras like these in China.
Thus, the cameras couldn't be set up openly in public, so it was best for two people and one dog to work overtime.
If this was handled by the PDD, it would take a team of several people to complete the entire process.
It was hard to hide too many people and too much activity.
