The surveillance camera is fixed. What is the visual field that can be monitored? What is the angle? Can it be monitored underground?

Fixed cameras have a certain angle of view, so there must be invisible corners in your dormitory, but they are basically unimportant corners. Since the dormitory will not be very big, your daily activities can be monitored.

The power of a video camera is 3-6 watts, plus a DVR for video recording, a * * * will not use several degrees of electricity. So you don't need to turn it on or off, you have to turn it on every day, including when you turn off the lights (if it's an infrared camera, you can see clearly without turning on the lights, just black and white)

How to handle it: If your privacy is violated, you can report it to 1 10. This is illegal.
