Description: _x005f_x000D_ 1. 5W high-power 850 infrared lamp (with adjustable resistance and photoresistor to automatically turn on 5W high-power LED lamp according to ambient light). _x005f_x000D_ 2. Adjustable resistance, small screwdriver can be used to gently twist to adjust the ambient brightness whether to turn on 5W LED lamp. _x005f_x000D_ _x005f_x000D_ Working Principle: _x005f_x000D_ 1. The LED lamp board and the PCB backplane of the camera can be used by screw lock together (for raspberry pi does not need software control. The lamp board works when the light is dim, the LED lamp opens automatically, and the LED lamp closes automatically when the light is strong. The premise is that the adjustable resistance of the lamp board needs to be adjusted properly. Our default shipment is not adjusted, because each customer uses a different location and location.) _x005f_x000D_ 2. It is automatically turned on by default. If it is not adjusted, the LED light will always be on, so it will be easy to heat up. Families who use it for a long time suggest sticking a radiator. _x005f_x000D_ _x005f_x000D_ Specification: _x005f_x000D_ Packaging size: 100mm*55mm*10mm/3.93*2.16*0.39'' _x005f_x000D_ Packing weight: 6g _x005f_x000D_ _x005f_x000D_ Warm Tips: _x005f_x000D_ 1. Because the power for raspberry pi is limited, when photography objects within 1-2 meters, the effect is better, too far, the effect is not ideal. _x005f_x000D_ 2. Because this infrared lamp is 5W high power, when the raspberry pie is connected with 5V 2A power supply, the peripheral equipments have mouse and keyboard, and the cameras and two 5W infrared lamps can work normally. But when used for too long, the power chips and two 5W infrared lamp for raspberry pi will generate different degrees of heat, so we should pay attention to the problem of heat dissipation (external radiator can be attached). At the same time, the additional power consumption of the whole board for raspberry pi should be considered. _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Please allow 1-3mm differs due to manual measurement. _x005f_x000D_ Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding. _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1 X Infrared Automatic Night Vision Sensor Camera Module
