Infrared and floodlight failuer after 1 month

I installed a Netatmo Smart Outdoor Camera with Siren about one month ago.

The camera works perfectly during the day (video stream and connection are fine), but recently at night the image is completely dark: neither the floodlight nor the infrared LEDs turn on, either automatically or when I try to switch the light on manually from the app.

I have already checked that night vision is enabled in the app and I have power-cycled the device, but the issue remains.

It looks like a failure of the light/IR module. Since the product is almost new, I kindly ask for a replacement under warranty.

in attachment you will find the proof of purchase.  I bought 4 cameras on Amazon and can provide invoice. 

please contact me to my email since there is NO support email address on show on this website. 

kind regards
