The Wanscam support sent a new firmware for my hw0022 cameras, and now after fw upgrade my cameras support  onvif protocol. I use it now with nvr mini plus. Pleas write to wanscam support. 
  
  
Hi gabeszakem, 
  
Could you please sent me the firmware too ? I've contacted Wanscam but they don't want to give the firmware for some reason.... 
  
I would be great to use ONVIF on my HW0022. 
  
Thanks!
