For goodness sakes, DO NOT BUY THESE. I bought 4 and sent them back repeatedly. they NEVER EVER fixed them correctly. I shipped them back to the company and received a nasty phone call asking me what they wanted me to do with them. He was so rude, I told him. The biggest waste of money. Ever. Do not buy.
If you sent that many back I am guessing you may have had PIPCAM5 or PIPCAM8 cameras from one of our early shipments. We have since corrected the problematic firmware with all the new cameras on the market.
I sincerely apologize for our negative experience with my company and would be happy to help make up for it the best I can.
