This is a nicer camera than the TV-IP743SIC that sometimes is on sale cheaper because it has a micro SD card slot and wider angle lens. You can put it in the corner and see the whole room. Lots of other features like multiple video profiles with their own URL, recording to a network SAMBA server, and more that I haven't used yet and was surprised to see in a camera this price.
Comes with the usual cloud services, but I don't like using them and it works fine as a stand alone camera if you have the network skills to set it up that way. WPS button makes it easy to connect without their app.
I bought one then after setting it up and testing I liked it so much I ordered a second one at this price for a spare.
