I bought 4 of their camera,. They look good and are discreet and the picture is nice. But they stop working with no reason. Sometimes they stop charging all together (I have them all usb connected to the main). One other incredible defect is that you can't record non-stop. It only detects a mouvement, records 10 or 30 seconds, and stops for several seconds or minutes, and then records again. So it is useless.
As for customer service, the guys are incredibly unprofessional and efficient. I tried for one year and 1./2 to sort out the problems with them but they just don't know. We have had more than 30 email exchanges always about the same problems.
I asked them to speak on the phone and guide me. They answered that I was living outside the catchment area for verbal support. I live in London, UK. As a summary, they have a very good product but with too many issues, it bogs and they don't have the personnel to fix problems.
I have thrown money by the window buying these cameras and will throw them to the bin looking for a reliable company.
