Raspberry Pi night vision camera adjustable-focus module

ER 00161 1.jpg

Description

This is a Raspberry Pi camera that supports night vision and focus adjustment.
It is connected to the Raspberry Pi through the CSI interface.
It is usually used as a night surveillance camera or anti-theft surveillance camera.
Many fans use it to DIY their own project.
The night photography project, the principle is that the night vision surveillance camera generally uses an infrared night vision camera.
The working principle is that in the dark environment without visible light or low light,
the infrared light emitting device actively projects the infrared light onto the object,
and the infrared light is reflected by the object. Enter the lens for imaging.
It supports Raspberry Pi 2B/3A+/3B/3B+/4B/Zero/Zero W

Notes

The LED fill lights on both sides will warm up(generally in 40 to 50℃) when they working, 
but it is normal, please don't worry, they can keep working 24 hours aday, it will not damage the camera normally. 
You can adjust the micro adjustable resistor(beside the lights) to turned down the lights to Lower temperatures.

How to Use the camera

  • 1. Connect the Camera
 The flex cable inserts into the connector situated between the Ethernet and HDMI ports, with the
silver connectors facing the HDMI port. The flex cable connector should be opened by pulling the tabs
on the top of the connector upwards then towards the Ethernet port. The flex cable should be
inserted firmly into the connector, with care taken not to bend the flex at too acute an angle. The top
part of the connector should then be pushed towards the HDMI connector and down, while the flex
cable is held in place.

  • 2. Enable it on Raspbian

Open the raspi-config tool from the Terminal

 sudo raspi-config 

Navigate the Cursor to Interfacing Options and then select camera and enable it. Reboot your Pi after setting.

  • 3. Taking Photo:
 sudo raspistill -o image.jpg 
  • 4. Shooting Video:
 sudo raspivid -t 20000 -o video.h264 

-t means it will last for 20s, -o means "OUTPUT file"
More info please using:

 raspistill -h 
 raspivid -h
