@Stella.Q Hello, I also need to downgrade the firmware because of whitenoise problems. Please send me middle firmware and help me to find the 1.3.4 firmware.

@sferrariba Same here, we are using it for baby monitoring. Everything was fine about 2-3 months ago... Then this whitenoise started to appear on every NC450 we have... At first I thought hardware...

@trentmichaels8 Are you serious? I have 4 NC450 cams and using with the latest firmware... All having whitenoise, no other sound... PLEASE FIX IT ASAP..

@DL2ROY I also have the same problem and I think it's related with TP-Link servers. Hey TP-Link, fix those servers!!!!!!!!!!!!!
