They claim that there is a 90 day warranty. But I spent 2 days programing and setting it up. And a day later the fan for the power supply unit went out.The only warranty there is according to Amazon is to return for price paid.And the first guy I talked to said they could discount what I paid. But then when they refered me to a manager changed their mind to just a refund on return.Oh and also it didn't come with a power cable. Had to take one of my back up PC
