I have purchased 3 different systems over 2 years. Genetically I have had good experience with my wireless cameras. About 3 weeks ago, one of my cameras started to freeze up and had to be reset. I called to get a replacement under warranty. That is when the experience turned south.....they had me reposition the image on the monitor....it was intermittent so I had to wait a few more days...it failed again. Called tech support and they wanted to do x.....I felt like they were more interested in kicking the can down the road than replacing my camera. I asked to speak with a supervisor....he finally agreed to replace it. Done deal right? Nope. Several days later I get an email that says it will take 4-6 weeks for a replacement unless I call them and give them a credit card for an advance exchange....why was not this solution offered last week? I am now on hold for over 30 minutes. Reasonable product.....but they really try to avoid warranty replacement at all cost!!! And one of my favorite calls....I had the pleasure of talking each time to our "offshore friends".
