I'm currently using the Eufy ecosystem.  Got a 5 in 1 security package with the homebase 2 and 2 x 2c Pro 2K cameras mounted internally.  The homebase 2 has 16GB local recording but can't upload once a clip has saved unless you pay for the online package which currently reduces the quality to 1080p. The system can do RTSP to a NAS or other software for constant streaming in addition to the alerts being uploaded.

So far has worked well, cameras are good and the actual security stuff including the keypad works well.  Will link with the wifi touch lock and doorbell cameras but not all the cameras will work with the homebase 2, I bought two internal pan and tilt expecting htem to link but they're seperate and need arming seperately to the main system but recordings are stored as part of the online package or via local SD Card.

Its quite immature software wise and needs work but it appears to be a relatively new setup.  Amazon.com.au is much cheaper than local purhcase for these... Arlo is apparently releasing a security alarm package sometime soon so that may be worth watching, especially if it is more robust as Arlo has been around longer than Eufy.

So far I'm happy, but time will tell whether Eufy continue to add products and make things compatible as they said they would but haven't.
