Hello everyone,
I'm working on a battery-powered night surveillance system using a Raspberry Pi (Model 4B) with a NoIR camera module and 850nm IR LED modules for night vision.
To optimize energy consumption, I plan to:
Capture an image every 1 minute during the night using the Pi camera.
Avoid keeping the IR LEDs on all night, as this would unnecessarily drain the battery.
Power the IR LEDs from an external power source (not the Pi camera module).
Control the IR LEDs using a GPIO pin: turn them ON briefly before capturing the image and OFF immediately after.
![❓]()
My Questions:
is that possible?
if yes do i need some electronic components?
is there another way that deactivate or disconnect to the camera module and then reconnect it to take a picture?
is there some one how tried or thought about this before?
Thanks!
