Hmm … I too am considering a surveillance cam for my 2022 ZSEV Essence. A couple of conside come to mind having done a little research about this in general (but not specifically for the ZS EV).
Would prefer dual front and rear cameras, 4K, good night vision etc. Plenty of those packages about, incl. installers that come to your home if necessary.
Would seem that hardwired might be the best solution given front & rear & possibly some other misgivings & limitations about the USB power option [?]
Mostly though, it would seem that a lot of these cameras - usb or fuse box powered - turn off and are not useable while the car is parked. But apparently, there are also some than can run in a ‘sentry’ mode by using a secondary internal battery [?]
Any thoughts or recommendations? Thanks in advance.
