RE:SURE I/O acts as a smart alternative to a physical keypad. It is an IoT app for remote control of CCTV systems, gates, lights – virtually anything. RE:SURE I/O works with www.resure.co services to give end-users seamless control of their monitored CCTV systems. Not only does it allow to check the status of your alarm or CCTV system, but it gives complete visibility and transparency of who has done what, and complete control who can access your property. Unlike a keypad, where no one knows who has the code, in this case new users can be added, and existing users deleted, with a single swipe. Features: + Manage up to 4 zones/devices per site + Control multiple site + Give zones/devices custom names. + 24/7 Activity Log + Arm/Disarm reminders + Multiple users with two user levels (manager and standard) + Works with any NVR/DVR type + Latch and pulse options available on each switch type – you decide which depending on what you are controlling
