There is a red light flashing on the smoke alarm in the bedroom. Is that a camera? Can you cover it?

The smoke alarm has a red light flashing, not a camera, but a sensor of the smoke alarm. All smoke alarms are available, which proves that they work normally. Real infrared cameras don't have red lights flashing.

The smoke sensor is not a camera, and a regular smoke sensor will not have a camera, but it does not rule out that some lawless elements will tie the smoke sensor and the camera together and do illegal things. You can also search casually on the internet and buy a smoke camera.

The smoke detector will blink, which is normal, indicating that it is running. If there is smoke indoors, it can call the police in time. The camera inside the smoke sense is hidden, and there will be no red light flashing.

The difference between smoke detector and video camera

1, which are essentially different. Smoke sensor is an alarm that can sense smoke, and it will blink when it works normally. If the indoor smoke reaches a certain standard, an alarm will be issued. And it will always be open under normal circumstances. But although the camera has a red light, it refers to the infrared camera. Generally speaking, there will be no flicker problem.

2. Their functions will also be different. Smoke detectors can monitor the concentration of smoke and prevent fires. The installation is relatively simple, and it is widely used in schools, factories and hospitals. Infrared camera is mainly based on infrared ray, which plays a monitoring role.
