1、3W high-power infrared LED. 2、Light-sensing Infrared LED Board, Wider Field of View. 3、Onboard photoresistor, the ambient light detector. 4、Onboard adjustable resistor, for controlling the ambient light threshold of toggling the infrared LED. 5、Suitable for Raspberry Pi Night 500W Vision Camera . This product is especially designed for Raspberry Pi Camera. With this IR Led light, you can clearly take photos within 2m at night, which brings more convenience to your life. Features: 3W high-power infrared LED. Light-sensing Infrared LED Board, Wider Field of View. Onboard photoresistor, the ambient light detector. Onboard adjustable resistor, for controlling the ambient light threshold of toggling the infrared LED. Suitable for Raspberry Pi Night 500W Vision Camera . Specifications: Product Color: Black Led: IR Led Power: 3W Application: Suitable for Raspberry Pi Night 500W Vision Camera Package Weight: 20g How to Use: 1.Connect the Infrared LED Board to the camera PCB by screws 2. The screw holes are used for both attachment and power supply 3. Adjust the adjustable resistor to set a proper ambient light threshold, which toggles the infrared LED automatically 4. When ambient light is lower than threshold value, the infrared LED is on, vice versa Note : 1. Limited by the Raspberry Pi power supply, the ideal imaging distance is within 2m. When the distance is far than 2m, the image effect is not good. 2. The number of night vision camera applied to for Raspberry Pi is two. It is suggested to purchase 2 or even numbers. Package includes: 2 x Infrared LED Light (Others are not included)
