Onboard 3W power 850 infrared lamp.
Onboard photosensitive resistor (detects ambient light intensity).
On-board adjustable resistance (adjusts ambient light intensity threshold for automatically turned on infrared lamp).
The field of view is 140 degrees, and the RPi Camera (H) is used to achieve infrared night vision.
Screw the LED lamp board to the camera PCB bottom plate.
Adjust the adjustable resistance on the lamp board (when the light is dark, the infrared lamp works automatically, when the light is strong, the infrared lamp automatically turns off).
3W high-power 850 infrared lamp (with adjustable resistance and photosensitive resistance to automatically turn on the 1W high-power LED lamp according to the ambient light), adjustable resistance, use a small screwdriver to gently twist to adjust the ambient brightness to turn on the 1W LED lamp.
The LED lamp board and camera PCB plate with screw lock together with (RPI don’t need to do a software control, lamp plate works when the light is dark, LED lights automatically open work, strong light, LED lamp automatically shut down, the premise is to adjust the adjustable resistance of good light board, we the default delivery is not adjustable, because each customer USES location and location is different, so is the default to automatically open, if not on the whole, the LED light has been bright, it will be easier fever, if use advice posted a heat sink for a long time.
1. Due to the limited power of RPI power supply, objects within 1 meter to 2 meters will have a better effect. If they are too far away, the effect will not be ideal.
2, because the infrared lamp is 3W power, RPI in 5 v 2 a power supply, peripheral devices are the mouse and keyboard, camera and 2 1 w lamp, RPI and camera can work normally, but time is too long, when using the power of the RPI chip and 2 1 w infrared lamp, can appear different degree fever phenomenon, so pay attention to when using the cooling problem (external heat sink), at the same time to consider the RPI board for an additional power consumption equipment.
3. The price is the price of one lamp. It is recommended to use two lamps at the same time.
