I ordered the wired version, but I immediately changed for the WIFI version that is more convenient. The supplier has changed the current order and refunded the difference. So big congratulations for the very serious and reliable supplier. The scope of the WiFi signal covers 25m and quietly filing is perfect. Very easy to install in my Orange Livebox network. As against the Foscam software, supplied with the product, at home, not working at all. the camera is not displayed. I use a free version of "Sighthound" works perfectly.
