Check the status of the camera: If the camera has a red light bead array on, it means that infrared lamp is working and the camera is on. If you need to turn on the camera during the day, you can climb under the camera and cover the camera with your hand, so that the camera mistakenly thinks that it will automatically turn on the infrared light.

Listen to the sound: If the monitoring equipment makes a faint hum or fan sound during operation, you can judge whether the equipment is turned on or not by listening to the sound.
