I have a Chinese DS-2CD2332 Camera running 5.1.0 
  
It will not detect motion/record to a Hikvision 9616-NI-SH NVR 
  
I have connected other cameras to the NVR and they work perfect 
running 5.0.0(china), 5.0.2 (china), and 5.1.0 (US Version Camera) work fine 
  
Should I upgrade this camera to 5.1.6 (or 5.1.2)  
  
Or downgrade to 5.0.0 or 5.0.2 
  
and if so, what would be the best way so I don't either turn this camera into a paper weight or have to learn Chinese in order to set it up. 
  
Thank you
