Can the flashing red in the hotel be a camera?

The flashing red in the hotel can't be a camera. In hotel rooms, we often see flashing red lights. Don't flash for ten seconds. This is actually a fire alarm light installed. When there is some smoke or oil in this room, this alarm lamp will give an alarm and spray some water directly, so that the fire can be put out directly.

It's not the camera that flashes red dots in the hotel. The red light emitted by the infrared camera is continuous and will not flicker. Most of the flashing red dots are sensors, such as smoke sensors that alarm and spray water after a fire. If there is a camera, when the indoor light is dim, the camera will automatically turn on the infrared lamp and use the mobile phone to wander around the room. If you find a red dot, there is a camera. If there is no red dot, there is no camera.

Overview of camera

Camera, also known as computer camera, computer eye and electronic eye, is a kind of video input equipment, which is widely used in video conferencing, telemedicine, real-time monitoring and other fields. Ordinary people can also have video and audio conversations and communicate with each other on the Internet through the camera. In addition, people can also use it for various popular digital images, audio-visual processing and so on.

A camera generally has the basic functions of video shooting/transmission and still image capture. After the lens captures the image, the image is processed by the photosensitive element circuit and control element in the camera and converted into a digital signal that can be recognized by the computer, and then input into the computer through the parallel port or USB connection, and then the image is restored by software.
