It is a reliable and powerful product. Are operating has free hosting on the cloud TrendNet. There are applications for viewing images on smartphone and tablet. To have it tested in several European countries, we can access the camera in wireless and in 3 or 4G. Under WiFi free, this is not the case with the telephone network. The only thing that does not work or is poorly explained what is the activation of alerts by email. It lacks specific examples or configuration assistance. In any case I have not managed to enable sending Email, there is always a configuration error! Despite this I would recommend the product because it is in a very good price / quality ratio.
