The hotel has turned off the lights. Can you still take pictures?

The camera in the hotel room can also take a clear picture when the lights are turned off.

Because most cameras have night vision function, they can shoot at night. At present, most cameras on the market are equipped with far-infrared devices, which can take pictures even without lights, but the picture is not as clear as during the day, and it is black and white.

Cameras can be installed anywhere in the hotel, so be sure to pay attention when staying in the hotel. If you feel unsafe, you'd better dim the lights in the room and turn off all the lights when you sleep, so that the picture taken by the camera will not be so clear.

When staying in the hotel, you should carefully check the room, do a good job of prevention, and check whether there are abnormal or redundant ornaments in the clothes hooks, sockets and hangers in front of the TV.

Compared with infrared cameras, white-light surveillance cameras have the following disadvantages:

1, white light fill lamp belongs to visible light, which is low in concealment and not suitable for covert monitoring.

2. Because the light of the white camera is visible, the director has a great influence, so the bulb decays for a period of time, which is easier to reduce the night vision effect than the infrared lamp.

3. In terms of price, the market price of white cameras is generally about 10% higher than that of infrared cameras.
