Designed specifically for rental living, this security solution requires no drilling and allows for quick installation and removal. It causes no damage to walls, doors, or windows, and can be completely removed when moving out. All core components are wireless and battery-powered, eliminating the need for complex wiring or construction. The system includes door/window contact sensors, motion-detecting cameras, and audible/visual alarms, focusing on securing entry doors and balcony windows. Devices are installed using adhesive mounts, enabling full deployment in just minutes. If an unauthorized entry or abnormal opening of a door or window is detected, the system sends an instant alert while triggering an on-site audible and visual alarm. It supports flexible arming—easily activated when leaving and deactivated with a single touch upon returning home. The equipment is portable, reusable for future moves, and cost-effective. With no permanent modifications required, it avoids the risk of damaging a rental property while meeting the need for anti-theft security during short-term stays.
