Most cameras won't automatically pop up on the TV if there is motion, it depends on the app interface on the TV. Can you download apps from the Google Play Store or are there just a few apps built in? If you can download from the Play Store you can get most cameras to show up on the TV. Also are you planning to run POE cables to the cameras or are you looking for wireless with just power to be run to the cameras, or completely wireless (battery or solar powered) cameras? There are many options out there but your TVs capabilities will be the deciding factor. Many systems Like Ring, Nest, Arlo, Blue Iris, . can be presented on Android devices Blue Iris would likely need to use the IP Cam Viewer app on the TV, Arlo is free with 7 days of motion recording for up to 5 cameras, where as Ring and Nest recuire paid plans for recording storage, Blue Iris can be used to record and alert on motion for just about any IP camera that is RTSP or HVIF compliant (HikVision, Dahua, and many many more) and costs aroud $60 for the initial purchase of the software but no monthly cost but you need to install it on a Windows machine that needs to stay up all the time on your network and all storage is local so you purchase whatever size drive you want depending on how long you want recording to stay around, it also can support up to 64 cameras and since the storage is local it takes up almost no internet bandwidth compaired to the others, so it leaves more room for other things like streaming services. However each camera takes a little more time and effort to setup in Blue Iris since it isn't a proprietary system like Ring, Nest, or Arlo.
