Cheapest ever according to 3camel.
This is powered by USB and the power adapter is 110-240v compatible. So you could either not use the supplied adapter at all and use any USB adapter, or just buy a plug US to AU plug converter.
Doesn't require the hub/base station unlike the standard Arlo cameras. This also has 2 way audio whereas the wireless arlo has no audio (and is 720p and battery powered only). The Arlo Q is 1080p.
Can save an additional US$5 if you're eligible to reload your gift balance with $100 to get a bonus $5.
The only thing going for this Camera is that it's fully wireless. What's the point buying it wired. Much better options available for that price.
