Second downside, monitoring with mail sending during a detected motion does not work well in fixed IP (with freebox). If you put it in DHCP (Dynamic IP), sending emails work. To configure it, use a dynamic IP preallocated to the MAC address. Attention there are two MAC addresses: one for Ethernet and one for wifi. The wifi is not displayed, it must be read with arp. The ports are redirected correctly with UPnP.
It does not allow for areas outside against motion detection (to avoid false detections due to trees, cars on the street, etc.).
Conclusion: Suitable for all completely basic facilities (at home to monitor his remote home). PS: I tested several, I feel that it's still the best in this price range.
