Playback enables you link recorded video footage from you DVR/NVR to your Olarm APP’s zone activity history. When a zone is activated, this event is stored in the app’s activity log which will then have a 10 second clip attached to the log entry.

You will need to enable the NTP (Network Time Protocol). The NTP function allows a device that is connected to the Internet to sync time with a NTP server. This ensures the time on your camera's and NVR is accurate which then allows the Olarm MAX to match zone activity events to recorded footage for playback in the Olarm APP.

• Click on the “Setting” icon

• Select “System”

• Choose “Date&Time”

• Toggle the “Tick box” to enable NTP
