The battery power cam does not detect through glass. Are you trying to use the camera in a vehicle like a dash cam? There are some members that have used the wired version of the V2 cam (Not the Outdoor V2) and V3 cams to record in vehicles but they had to set up the cam on Wi-Fi at home. There is a complicated post about that around someplace. The battery powered V2 cam will record continuous to a SD card in the cam using scheduled event recording, continuous but it will kill the battery in 6 hours or less. The SD has to be a 32GB card or maybe a 64GB card formatted in FAT32 for the outdoor V2 and the ability to view what is on the SD is an awkward affair. Your use situation sounds complicated 
The V3 cam can record through window.
