The Reolink 5MP cams serve me well at home and I don't need a NVR or anything like that,just:
1.The cams with a 64gb SD card in each for motion recording.
2.POE switch connected to the internet and each cam.
3.The app on my phone/ipad/whatever device you want to access it from(could even be your android TV box I suppose).
I've setup motion zones at low sensitivity to minimize false alerts without sacrificing reliability,but that said things like lighting strikes and heavy thunderstorms do give me lots of false motion alerts for that period of time on the standalone reolink solution.
They're $50 at Amazon but I bought them cheaper last black Friday so might wanna wait for that.

The night vision isn't the greatest but my yard is lit up so they work great in my situation I force them to stay on colour mode and they're very clear,also the cams with proper night vision like hikvision darkfighter 2/Dahua super starlight are minimum $130 per piece before shipping etc and they would need a dedicated NVR or a Blue Iris PC to work.I wanted something simple that I didn't have to mess with IP addresses etc at home,plug and play,affordable yet clear.
At work on an older system I do have proper Tiandy Super Starlight cameras(bought from
http://www.viscon.co.za) connected to an NVR and for certain areas where I need reliable motion alerts I run those cams also of a blue iris PC.
Now for the part which may help the OP somewhat with false alerts is the sentry ai portion add on for blue iris,I'm still trialing it but so far it does seem to not alert me for silly things like birds or thunderstorms.
