For 7 years I use cameras, it is very light, offer sound, wifi or ethernet cable. You can assign an access password You have to download the MAC OS X setup program on the site [...] it needs Java 6. On the mac SecuritySpy monitoring program recognizes it without problems, if not via the mydlink website also works with java. By connecting the 1st time the camera, she gets an IP address automatically through the box or router. I advise you to give it a static ip address. Wifi by pressing the WPS button on the camera and then the on the router or the box, it automatically configures itself. To access via outside, open a port on the Freebox or livebox. It has no night vision but did nicely for a restaurant or other public place.
