Amazon side nothing to say, this is perfect: as well as treatment delivery return. Side hotline Tenvis is great too: the Chinese hotline answers in English very quickly (few hours max) and relevant way. Unfortunately the product is not up to par; probably not developed or poorly designed: very unstable software often requires rebooting the camera very temperamental web access; work very random with no apparent cause impossible to walk shipment of email impossible to make check-in alarm capricious direct recording suddenly panning is limited to 180 ° In short, after losing more than a day to try to operate the camera, despite the effective help of the hot line Tenvis I returned the product to Amazon. Very simple and extremely quick refund procedure (I'm Premium client). I'll probably buy an IP camera with night vision, but I will agree to pay a little more (probably 70 to 100), hoping that this will ensure quality.
