Infrared surveillance camera at night (no light) no picture and flash is how the matter
Is the daytime image normal? If the normal day, it is likely that the infrared light-related components are broken, there may be problems with the photoresistor.
Check the time, pick the evening when people come close to the camera from the place to see if the infrared light is not activated, if the start, the infrared light will have a very weak red visible light is always bright. If there is no red visible light or not always bright, it can be basically the problem of infrared light. Of course, you also need to check whether the power is normal, if the voltage is low or the current is too small, it may cause the infrared light does not work.
Infrared light will flash, or no picture of the screen. First change the power, not the case, this camera should be broken. Under normal circumstances, in the dark, the infrared light is always bright, not flashing.
