Ryan from Terre Haute, Indiana wants to upgrade his duplex and install surveillance cameras inside and out. He wants a closed system, but he doesn’t want Wi-Fi to piggy back on. He also wants to use this as a tool to make sure his teen son isn’t sneaking out at night. Overall, he wants a closed system that sends motion detection alerts when his son is trying to leave the house. He asked if I have any recommendations for systems that will send motion alerts (he doesn’t want to review eight hours of footage to find any escape attempts).
