While researching for Home Security Cams and after finding most of them were expensive, I was able to find Sens8 lightcam via their indiegogo campaign.

Unfortunately they do not deliver to Australia but I've used MYUS account for shipping. Yet 5 Cam's and shipping will cost me approx $500 AUD which is way cheaper than Reolink, Arlo, Ring, etc.
Oh btw, one of the feature is the Cam has a 8 GB built-in storage with the ability to connect to your google drive / dropbox account and upload directly via WIFI.
Seems like a decent price… IF they dont run into trouble and they actually endeavour to get it to customers.
