Hi Dmon,
We would like to encourage people to use better options, thus why the strong encouragement of using a wired setup vs wifi.
That particular model you are referring to I believe is the IPC-HFW1320S-W
http://www1.dahuasecurity.com/products/ipc-hfw1320s-w-5631.html
It has local on board microSD storage, so that's good when you lose WiFi - it can still be recording.
Remember the camera is typically sold from Aliexpress vendors without a AC power adapter - so remember to add that.
Costco recently had the Q-see branded version of that w/an adapter being sold for $80
It's a decent enough product AND far better than the zmodo cameras, however there are newer models which are very well liked here due to better night time performance.
( in particular the Dahua starlight series of cameras )
I understand if you're on a tight budget and looking for something which works and want something which does not require the wiring work.
You'll have to trust a number of us who have also gone down that road and found that we probably should have just started with wiring up our system.
Do feel free to pick up one of those cameras and start playing with it to get a better idea of what you may want or need in your next camera.
