Cinepolis India — query on night vision cameras in cinepolis

While watching movie and when lights are dim, i have noticed that green leds blink constantly.

As an audience, there is no information to us about surveillance.

So, i have two questions as below:

Are there any night vision cameras in cinepolis across pan india?

What is the green led blinking equipment on both sides of walls of cinepolis cinema hall?

Need two separate answers for above two questions.
