Are there any technical parameters for the LED fill light of the camera in video surveillance? Is there a difference between good and bad?

The fill light in the surveillance camera is a kind of fill light method, which is used to improve the situation that the light in front of the subject is insufficient when the subject is backlit!

This kind of fill light lamp is generally made of high brightness light emitting diode (LED), which has the characteristics of stable operation, low calorific value, low energy consumption and long service life! As for the parameters, such products are generally not clearly marked! However, you can refer to the performance parameters of the highlighted led to identify it!

At present, the commonly used high-brightness LEDs are all 5mm!

Main parameters: model: 5mm
