This looks like a good deal on this security camera. Last time it came down to $120. Who knows, some JB Hi-Fi Store Rep might bring it down further for you, if you buy more. Try calling them or online chat? This price has been like this for the past 2 weeks or something, so not sure if it's an Straya Day special or not. It' has 8GB of sufficient internal memory. Some other nice specs too.
The Good Guys have it for the same price, but it's out of stock there I think.
I have used Eufy cameras before. Easy to use, reliable and not much fuss. Not sure compared to other brands. Good thing about this one is that it doesn't need a Homebase. The mobile phone App is easy to use too.
Does it do continuous recording? RTSP?
Edit: Just checked. It does not.
