Polling is where a path (say ethernet or 4g) is polled every x seconds/minutes to check the path is actually available to deliver alarm events. The comms device sends a signal that is acknowledged and responding to. After x no of failures and event is reporting to the monitoring station of a total polling loss. This is then reported to the monitoring station as a total comms lost and is reported to the police if armed(on URN systems)

Old man used to rally them with his dad, he was from Cumbria. Bought my sister one even tho I said it was a bad idea due to what I'd walked away from in newish cars. Had a smack nothing like my sort of scale, has plates in her arm was lucky too looking at it after, but did it handle for a little thing
I use a fob, but I don't have my address on my keys. It's a bit like contact less payment it's just easier but I do use a code in the morning or tge app on the phone
Also chances are your car is worth more than the stealable contents of your home
