I just purchased a Hikvision DS-2CD2032-I and need a power supply.  I found that I had an old one that is DC12V/1.50A but noticed the power supply with jack connector for sale on the Hikvision site is DC12V/1.25A.  Does it matter that the output of the one I have is .25A higher than what Hik offers? 
  
I plan to use a POE injector and run the ethernet about 80 feet from the power supply.
