Outdoor Cam v2 in Travel Mode as security camera

I’m testing to see if I can use the Outdoor Cam v2 in Travel Mode as security camera for a location that has no WiFi. A client wants a total of 8 cameras for this purpose. My question is if I am understanding the scheduled recording settings correctly or not. I assume I would set it as follows, Note, the Outdoor Cam v2 I am testing has a 128GB Micro SD card. And, I assume for maintenance of the camera, the client would have to recharge the battery on the camera as needed and restart the 30 day scheduled recording within every 30 days.
