The smoke alarm has a red light flashing is not a camera, it is the sensor of the smoke alarm, the general smoke alarm has, to prove that it is working normally, the real infrared camera will not have a red light flashing. Smoke alarm is divided into independent type, series type, network type.
Smoke alarm is one of the most important means to prevent fire, its role is used to detect a large number of smoke caused by fire alarm, smoke alarm sensitivity is based on the geographical location and application of the environment to consider, so as to achieve the user should have the effect.

operating principle
From the internal principle, smoke alarm is to monitor the concentration of smoke to achieve fire prevention, smoke alarm internal use of ionic smoke sensor, it is an advanced technology, stable and reliable sensor, is widely used in a variety of fire alarm systems, the performance is far better than the gas resistor class fire alarm.
It has a radioactive source americium 241 in the internal and external ionization chamber, and the positive and negative ions generated by ionization move to the positive and negative electrodes under the action of the electric field. Under normal circumstances, the current and voltage of the internal and external ionization chamber are stable.
If there's smoke escaping outside, call out the room. Interferes with the normal movement of charged particles, current, voltage will change, destroy the balance between the internal and external ionization chamber, so the wireless transmitter sends a wireless alarm signal, notifies the remote receiving host, the alarm information will be passed out.
Not a monitor, a sensor. Smoke alarm as a kind of fire protection facilities, in a variety of business places are necessary, this is a mandatory rule, only fire qualified, everyone's life and property safety will be guaranteed. The smoke alarm is not equipped with monitoring but sensors, that is, when the fire or the concentration of smoke seriously exceeds the standard, it will play an alarm warning role
The smoke alarm has a blinking light, which belongs to the normal patrol state, and there is no need to worry about whether there is a camera, such as the smoke device has no blinking light, which proves that the line is not working and needs to be maintained
