Camper Security

thanks guys, im actually looking for a parking spot in a quiet neighborhood in someone's drive way where ill be a lot more low key but there may be times where i need to park/sleep on city streets. Im in queens and there is a lot of residential options too. I realize this is a bit ambitious of me, but i only work 16 days per month so my plan is to spend most of my time upstate in the mountains. I need to figure out how to be safe when i commute to the city for work. I have an alarm picked out for the truck itself, as far as the camper itself, i found some sirens/alarm but was really curious to see if there was any standout product that we;re all using. thanks for the info
