Hi all!

My first post here! 
 

I've recently purchased and installed a C720 Floodlight camera to keep an eye on the loading bay at the office. 
 

It has been installed for a few hours now, and at complete random intervals, the camera displays white/grey lines across the image making it completely useless!?

I've found that changing frame rates will kick it back into life, but shortly after it will start to show the lines again.  
 

Power line frequency is set to auto though I have tried on both 50 & 60Hz, I've gone through all other settings and can not find anything in there that could help/cause it? Rebooting the device also cures it for a short time. 
 

I'm curious if this is a software glitch or a fault with the camera? 
 

I have the diagnostics enabled should anyone request the logs. 
 

Thank you!
