Worked once for about 30 seconds then it acts like you've installed nothing and requires you to repair all the cameras requiring you to physically Uninstall and bring them to less than 8 feet from the recorder to repair where it will immediately repair them and then immediately not show them paired in the next, attempting to force reboot will result in error force reboot not available. Absolute junk and expensive junk at that, saddest pile of garbage I've had the misfortune to use in many years.
